I don't use hibernate anyway but been trolling the Linux Mint forums somewhat lately and many were complaining of hibernation not working. sudo systemctl hibernate after reboot it should show all the same windows again. I will happily provide any additional info you need, just let me know. FAQ Hibernation does not work. @helloworld1 @diabonas I've updated the patch a bit to focus more on giving Btrfs swapfile users a way to disable the swap discovery logic. So 'shutdown' is a good solution for desktops which don't have lids you can lift to trigger a resume. Probably I don't understand swap space calculation correctly. gnome-shell-extension-hibernate-status. The problem is that hibernation through systemd does not work, in fact if I do: systemctl hibernate, I obtain: Failed to hibernate system via logind: Not enough swap space for hibernation. sudo apt install hibernate It will install hibernate and other dependencies which are needed to hibernate. By clicking “Sign up for GitHub”, you agree to our terms of service and Hibernation might not work. We use essential cookies to perform essential website functions, e.g. Learn more. Description of problem: systemctl hibernate no longer works as of 233-6 Version-Release number of selected component (if applicable): 233-6 How reproducible: systemctl hibernate Steps to Reproduce: 1. systemctl hibernate 2. Since Btrfs is using virtual physical offset of the file. to your account. We should have an interface (system call? That said, given that btrfs hibernation is a pretty new feature I think we'd also be fine to wait until the kernel learns a new hibernation API that allows us to just pass an fd in, and only support it when that's done. This operation is much faster than restoring the state from hibernation since the system state was not saved on the hard disk. You should also be able to see a debug message in the log that reads something like: Unable to determine available swap space for resume=8:17, resume_offset=487840; set SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK=1 to override this check. However in this case we cannot do any better at the moment anyway since calculating the file offset for Btrfs to find the correct file is not implemented. After some googling i still found no answer. virtual physical offsets are provided to have a consistent view of file addressing. If /sys/power/resume_offset has a previously set value, it assumes that value provided is for the swapfile detected in find_hibernation_location which reads from /proc/swaps. Created attachment 141241 Supposedly relevant logs from journalctl Problem: systemctl hibernate # Works fine systemctl suspend # Works fine systemctl hybrid-sleep # Black screen when trying to recover. The RAM, will not be powered off unlike most of the devices in the computer. We do that by parsing /proc/swaps and attempting to match a swap entry with resume= and resume_offset= values to make checking for space on the right file. I think this is the best course of action for a few reasons: if you are intending to use a swapfile on Btrfs you must have your system configured correctly (/sys/power/{resume, resume_offset} must be set with correct device id and offset which must be calculated) and if the system is not configured correctly, systemd will not be able to help discover the swap file for you by parsing /proc/swaps. I think this is by design for Btrfs since it can handle multiple storage devices. Unfortunately the latest patch does not work. privacy statement. sudo systemctl hibernate powers off the laptop, but after logging in no programs are running.

This means if the device given by the resume kernel command line argument has a Btrfs file system, find_hibernate_location will use the first swap file on the device listed in /proc/swaps. Systemd should just see if there is a swapfile on btrfs and disable the check. We use essential cookies to perform essential website functions, e.g. Thanks for your work. I realized while revisiting this code that the check to verify enough space cannot work consistently in cases where the user has multiple swap files configured on Btrfs. ... OP, one more: sudo systemctl hibernate -- there's no reason to sudo that one, either. Is the problem specific to BTRFS or all swap files? Based on the wiki instructions, I came up with the following: So I guess the problem is related to some control check in logind. In order to suspend the system, type in the command below as root: systemctl suspend The suspension command, will enable the current system state (complete context) to be saved on the RAM. Learn more, systemctl hibernate does not hibernate on swapfile on Btrfs after kernel 5.0. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. It does not check for /sys/power/resume or inspect resume= kernel cmdline. New Systemd 247 Is Out For Linux Operating System As Major Release. I've confirmed that this works in the VM I setup and confirmed that the calculation continues to take place in absence of a resume_offset being set. It needs to be in both. The only situation where I can see this failing is when there are multiple swap files on a single Btrfs device and the one specified by resume_offset is not the first one listed in /proc/swaps. It seems like systemctl hibernate give me the same error. Yes, as @helloworld1 said, Btrfs gives you a virtual device number for stat and a virtual offset for fiemap by design. activate automatic hibernation after delay. Nicoadamo 16:09, 10 November 2019 (UTC) Does systemctl suspend-then-hibernate not work for you? So we can't match the entries in /proc/swaps with resume and resume_offset and can't find the space in use. a) Wait for btrfs to change till this magically starts working? Already on GitHub? I think there are a few more kinks to work out in this patch. I pushed up a new change that removes the comparison for sys_resume and location->resume but tries to make a guess only in situations where there is a resume_offset= value >0 in an attempt to more accurately guess that the user is in fact trying to use a swap file. Used distribution. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. I submitted #12760 which solves the general issue of ignoring the resume_offset by implementing d) in @Snoop05's list above. Apparantly on Btrfs even the device ID from fstat does not match the actual device ID, so the quick fix above should read. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. Again, I haven't had a chance to setup my test environment for this but will a bit later today or tomorrow. this howto should help you to set up working hibernation with a swap partition on a fresh install of LM19. With this options, I can reliably hibernate and reanimate the SP3Pro from the command line with systemctl hibernate. Curious booted Hydrogen iso on usb and tried it there, nope, same thing. Sorry I wasn't clearer about that before. 241.7, Expected behaviour you didn't see @diabonas ahhh, yes. that just takes an fd and sets that swap device or file as the resume device. privacy statement. By clicking “Sign up for GitHub”, you agree to our terms of service and Successfully merging a pull request may close this issue. Or we currently parse sleep.conf multiple times, which sucks too. Or do you have any better ideas? systemctl hibernate was working in 243 but failed in 244 with error: Dec 04 17:21:09 liberty-pc systemd-logind[551]: /sys/power/resume and /sys/power/resume_offset has no matching entry in /proc/swaps; Hibernation will fail: resume=259:7, resume_offset=52582877 Differences are : In that case, the patch you applied allows hibernation to proceed successfully. I've tested the patch and it seems to work ok but if you're open to testing again I'd appreciate it. The steps described in OP are identical in my case. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. Unexpected behaviour you saw We’ll occasionally send you account related emails. Actual results: System tries to hibernate and does not show an error message if … Tech support For some reason, when I use systemctl hibernate or suspend, the computer turns de screen off, but doesn't shuts down. Since Btrfs is using virtual physical offset of the file. If not (for example, because another user is logged into a tty), systemd will automatically ask you for the root password. Verified swap file works and has enough space. Thanks for reminding me of that and providing the helpful link with more info. Already on GitHub? After linux 5.0, swapfile is supported on BTRFS. I'm affected as well by this since the upgrade to systemd 244. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. Thanks @helloworld1! Don't be so generous with your sudo. To start using this function you need to create a file. sudo systemctl suspend-then-hibernate Using low level interfaces directly is significantly faster than using any high level interface, since running all the pre- and post-suspend hooks takes time, but hooks can properly set hardware clock, restore wireless etc. system didn't hibernate $ systemctl hibernate Failed to hibernate system via logind: Resume not configured, can't hibernate journal shows: I am have applied the patch to 244 and testing it today. Current status: neither resume, nor resume_offset gets detected properly, yet systemd will override both. In order to match the swap file entry in /proc/swaps we need to calculate the offset...which we don't have support for right now when using Btrfs. Sign in Seems like hibernation on swapfile requires real physical offset to work. On the other hand, the most common case of at most one Btrfs swap file is covered. 3. sudo /usr/bin/systemctl enable xxx.service > /dev/null 2>&1 sudo /usr/bin/systemctl start xxx.service sleep 10 sudo echo "Finished." 2. The resume_offset kernel parameter is also ignored and overriden by systemd so it is unable to get the correct offset. Just tested your patch and the hibernate works great on system with unencrypted BTRFS and a single physical drive. However when I try to recover it immediately shows a black screen and stops there. Execution of multiple hibernations via < systemctl hibernate > is working as expected in virtual consoles. Hi @zachsmith. In my opinion, the issue is that the hibernate interface is stupid. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. d) Honor resume and resume_offset parameters set in cmdline instead of wizardry? Learn more, We use analytics cookies to understand how you use our websites so we can make them better, e.g. (unresponsive) It seems like it correctly enters hybrid-sleep state. Seems to be working but would love to know if it's working on real systems. You signed in with another tab or window. Unfortunately, this did NOT work for me :- they're used to log you in. Once you have the kinks, I will test again :). they're used to log you in. I was able to successfully test this workaround on a system with a single swap file on a (LUKS-encrypted) Btrfs file system. Successfully merging a pull request may close this issue. 3. Steps to Reproduce: 1. You signed in with another tab or window. You can always update your selection by clicking Cookie Preferences at the bottom of the page. In the Cinnamon menu, select "Quit", then "Hibernate". If you are in a local systemd-logind user session and no other session is active, the following commands will work without root privileges. The related discussion to get the physical offset of Btrfs swapfile is in https://bugzilla.kernel.org/show_bug.cgi?id=202803. Why not use the explicit offset that is set in the kernel parameters? fi exit 0 I'm sure that the service file already exists in directory /usr/lib/systemd/system, and I can start it manually using the command "sudo systemctl … If anybody using btrfs with a swapfile is game, please give the PR a spin. However, most of the time when hibernating from Gnome or by closing the lid, the resume fails (blank screen), the log giving my the hint that something with the i915 driver has gone wrong (sorry, currently no log available). Even in the single device case, we make use of the virtual offsets to simplify block allocation. Hope this should not be the case in the final patch since it clearly breaks existing setup. Maybe systemd should also read kernel parameter for the manually set resume_offset instead of calculating. I've pushed up a few more changes to handle some edge cases. I also notice that it hasn't created a swap partition with default installation settings, can this be related? May i ask how would people (with rights to merge pull requests) like to have this one solved? Once the machine is turned on, the state saved on the RAM will be restored automatically. Btrfs supports swapfile after kernel 5.0. echo disk > /sys/power/state works fine to hibernate but systemctl hibernate failed. systemctl hibernate should hibernate on swap file on Btrfs after kernel 5.0. Thanks for reporting this and sorry for the headache. The sleep code could generally use some love though. https://github.com/systemd/systemd/blob/master/src/shared/sleep-config.c#L436. Learn more, Systemd 244 Hibernation failed due to sys/power/resume and /sys/power/resume_offset has no matching entry in /proc/swaps. For example the s2h code uses RTC ioctls, where it probably should just use CLOCK_BOOTTIME_ALARM. system should hibernate. Would love to simply remove the previous code then and just use the new API. Learn more, We use analytics cookies to understand how you use our websites so we can make them better, e.g. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. When using swap files on Btrfs, the previous code would try to check for space and would pass in most cases but was not necessarily checking the correct swap file. Problem: First execution of hibernation in X works as expected. As a result, I made a small change that will intentionally cause hibernation to fail in some cases so you will need to set SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK=1 in your systemd-logind.service [Service] section. instead (i.e. Learn more. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. Sign in Rather than inspecting the kernel cmdline for resume= and resume_offset= (which was how I originally started), it simply checks for any value already present in /sys/power/resume_offset. I was finally able to test these changes on a VM. A suspended system is prone t… Any help will be much appreciated. There has been the ability to bypass this check for some time so you'll need to use that here. Because we can't detect the correct offset on Btrfs for the swapfile we can't correctly find the swap entry and we can't check the space. Use Cinnamon (for example). This was one of the edge cases I discovered today. We’ll occasionally send you account related emails. Also does that mean SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK for all cases that btrfs swap file is used? The route I took is fairly simple but I think it serves the purpose. The current patch will require that you add: to systemd-logind (logind checks for memory) and systemd-hibernate (attempts discovery to match swap files with configured devices) services. If it applies to all sway files, should we make space check bypass default for all swap files? Supports GNOME 3.36. Actual results: not hibernating Expected results: hibernate … it seems that suspend-then-hibernate is not a valid value neither for /sys/power/disk nor /sys/power/state. Gnome Shell extension that adds a hibernate/hybrid suspend button in Status menu. b) Implement btrfs swapfile support on systemd side? The system goes off, probably trying to hibernate even though it does not work. systemd services are enabled. I was able to reproduce this bug on a virtual machine running Arch using the steps @helloworld1 provided in the initial report. Actually, hold off. Any other multiple executions of hibernate of the same user session, not X session will … However I found the hibernation does not work correctly on 5.0 kernel. If you or @helloworld1 are willing to test it on your setups (especially with LUKS), that would be very helpful. systemd version the issue has been seen with. sudo nano /etc/systemd/sleep.conf add [Sleep] HibernateDelaySec=3600 try. https://wiki.archlinux.org/index.php/Power_management/Suspend_and_hibernate#Hibernation_into_swap_file_on_Btrfs, "highest priority swap with most remaining space", systemd-sleep: always attempt hibernation if configured, systemd-sleep: fix hibernation regression on Btrfs. Originally developed by @arelange; now maintained by @p91paul. ExecStart=/bin/systemctl … systemctl hibernate was working in 243 but failed in 244 with error: The resume_offset in kernel parameter is correctly set and hibernation works in version 243. The ioctl mucking is really terrible for this purpose. echo disk > /sys/power/state works fine to hibernate but systemctl hibernate failed. But in the end, when I suspend and come back, the VPN doesn't restart and I my Internet won't work until I run manually sudo protonvpn r . @diabonas and @helloworld1, I have not had a chance to setup an environment to test this fix with so if you have the time and are willing to confirm the fix I would be grateful. I'm waiting on additional feedback so there may be more changes to come so if you'd prefer to hold off that's fine too. Try launching from your terminal. How reproducible: Not sure. Though these interfaces can be used directly, it is advisable to use some of high level interfacesto suspend/hibernate. You should be able to do that with systemctl edit systemd-logind.service. https://bugzilla.kernel.org/show_bug.cgi?id=202803, systemd-sleep: refactor sleep conf parsing, systemd-sleep: use resume_offset value if set, Create swapfile on btrfs according to man 5 btrfs, Calculate the physical offset of swapfile and add kernel parameter, echo disk > /sys/power/state works fine to hibernate. Hence, yes, I'd be happy to merge a patch that makes sure we always use the kernel parameters if they are specified. [Unit] WantedBy=sleep.target After=systemd-suspend.service systemd-hybrid-sleep.service systemd-hibernate.service [Service] Type=simple ExecStart=/bin/bash -c 'echo awake from sleep' >> /tmp/awake.notes' Often this will be used to restart a systemd service. Hibernation failed, and journalctl does not give error log anymore also. So either my swapfile being on the /home partition creates a problem, or the problem is more related to swapfiles than to the file system. Thanks a lot @zachsmith for the hard work to fix the problem. Otherwise, I will pick this back up over the weekend. Yes, I added the same config to /etc/systemd/system/systemd-hibernate.service.d/override.conf and hibernation works fine now. Feel free to comment on the https://bugzilla.kernel.org/show_bug.cgi?id=202803 with Btrfs developer so we can have a consensus on how to address the issue. I also found another way to execute code on hibernate/resume, and it also did only work when removing the module before hibernation. Have a question about this project? Why does it works in version 243? Then I ran sudo systemctl start protonvpn-restart.service && sudo systemctl enable protonvpn-restart.service. Expected behaviour you didn't see. The current logic in sleep.c does not get the correct physical offset of the file. But sudo systemctl hibernate was not working. Hmm, so why does btrfs not follow the same APIs as other file systems on this? I'm not sure if Linux uses swap partition to hibernate. A program that runs elevated basically owns your system. to your account, systemd version the issue has been seen with @helloworld1 to try and answer your question, in order to correctly detect the remaining swap space, we need to know how much space is already in use. Thanks for confirming @helloworld1! Then when you hit power the kernel looks for a hibernate image and tries to use it. Looking at the relevant code in sleep-config.c, it appears as if the following happens: in location_is_resume_device so that the comparison can succeed on Btrfs filesystems. I have been affected by this bug as well, like @helloworld1, I use a swapfile. Got me curious tried "systemctl hibernate" on my laptops Debian Stretch install and nope, didn't work. Isn#t this a btrfs interface issue? As descibred in Arch's Wiki Power management#Sleep hooks, you can create a systemd service that is triggered by the sleep service. use the swap file on any Btrfs file system that is listed first in /proc/swaps). Just report back the latest patch works great on my system. Have a question about this project? Yes, please add that. Unexpected behaviour you saw. In the past we were just returning the first swap in the list and the space calculation would run and if you only had one swap entry that was your swap file configured for resume and resume_offset`, it would pass...but that was just coincidence. Millions of developers and companies build, ship, and maintain their software on GitHub — the largest and most advanced development platform in the world. I believe you'll need to reboot after making that change. The line looks like this. Victor Paul December 10, 2018 at 8:47 am. You'll need to set SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK=1 in the [Service] section of the systemd-logind.service. It basically means when the hibernate image is written to disk, shutdown. Elevated privileges should be given sparingly. I'm setting them up to test now but would very much welcome your testing help as well. I'll get a fix up for this soon. You'll also need to add the same value to the systemd-hibernate service. I thought it is just swap file size should be larger than image size. If it finds a value > 0 will assume that was set previously and return without any offset calculation or resume device override. And yes, SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK will apply in all cases - regardless of file system. For more information, see our Privacy Statement. I did have to use the utility @osandov provided in the issue reported in bugzilla to calculate the offset for btrfs correctly (in case anybody else tries it). 239.300-1. Suspend and Hibernate do not Work - Should I report bug? The message that you're seeing now is coming from logind and hibernation isn't being attempted because systemd can't determine if there is enough space. ioctl?) Thanks for the explanation. c) Rewrite this component from scratch? The current logic in sleep.c does not get the correct physical offset of the file. For more information, see our Privacy Statement. @poettering, would systemd make use of that if we were to implement it in the kernel? anything specified on the kernel cmdline should take precedence over any automatic discovery. Because we can't correctly identify the swap file, we can't correctly see how much space is in use so even if we know the size of the image and the size of the file, we won't know if it'll fit. grep swap /etc/fstab (find UUID) sudoedit /etc/default/grub At the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" add UUID of swap. It's not specific to Btrfs. The swap file offset is needed to match the resume= and resume_offset= values with a /proc/swaps entry and that is needed to check for enough space. . GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID of swap" You can choose One thing that did not work according to the instructions was the kernel suspend mode; on my case, it shows s2idle [sleep], not sure if that’s fine. Arch Linux. Arch Linux. I notice there is no hibernate option. Hibernation works with SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK in /etc/systemd/system/systemd-logind.service.d/override.conf The resume_offset kernel parameter is also ignored and overriden by systemd so it is unable to get the correct offset. Millions of developers and companies build, ship, and maintain their software on GitHub — the largest and most advanced development platform in the world.
