I'll get a fix up for this soon. grep swap /etc/fstab (find UUID) sudoedit /etc/default/grub At the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" add UUID of swap. In the Cinnamon menu, select "Quit", then "Hibernate". Millions of developers and companies build, ship, and maintain their software on GitHub — the largest and most advanced development platform in the world. 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. 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. Then when you hit power the kernel looks for a hibernate image and tries to use it. Hi @zachsmith. Any help will be much appreciated. 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 The current logic in sleep.c does not get the correct physical offset of the file. Have a question about this project? use the swap file on any Btrfs file system that is listed first in /proc/swaps). Thanks for reporting this and sorry for the headache. 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. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. In my opinion, the issue is that the hibernate interface is stupid. You'll need to set SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK=1 in the [Service] section of the systemd-logind.service. Once you have the kinks, I will test again :). ... OP, one more: sudo systemctl hibernate -- there's no reason to sudo that one, either. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID of swap" You can choose . Problem: First execution of hibernation in X works as expected. it seems that suspend-then-hibernate is not a valid value neither for /sys/power/disk nor /sys/power/state. I was able to successfully test this workaround on a system with a single swap file on a (LUKS-encrypted) Btrfs file system. I'm affected as well by this since the upgrade to systemd 244. Probably I don't understand swap space calculation correctly. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. You'll also need to add the same value to the systemd-hibernate service. Try launching from your terminal. Yes, please add that. 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. 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. I also found another way to execute code on hibernate/resume, and it also did only work when removing the module before hibernation. (unresponsive) It seems like it correctly enters hybrid-sleep state. After linux 5.0, swapfile is supported on BTRFS. ioctl?) Btrfs supports swapfile after kernel 5.0. echo disk > /sys/power/state works fine to hibernate but systemctl hibernate failed. Learn more, Systemd 244 Hibernation failed due to sys/power/resume and /sys/power/resume_offset has no matching entry in /proc/swaps. sudo /usr/bin/systemctl enable xxx.service > /dev/null 2>&1 sudo /usr/bin/systemctl start xxx.service sleep 10 sudo echo "Finished." instead (i.e. privacy statement. You signed in with another tab or window. I was able to reproduce this bug on a virtual machine running Arch using the steps @helloworld1 provided in the initial report. A program that runs elevated basically owns your system. For example the s2h code uses RTC ioctls, where it probably should just use CLOCK_BOOTTIME_ALARM. Thanks for your work. 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. 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. 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. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. The system goes off, probably trying to hibernate even though it does not work. they're used to log you in. Unexpected behaviour you saw sudo systemctl hibernate after reboot it should show all the same windows again. So I guess the problem is related to some control check in logind. Supports GNOME 3.36. sudo systemctl hibernate powers off the laptop, but after logging in no programs are running. Seems to be working but would love to know if it's working on real systems. email4shopping December 14, 2018 at 5:01 pm. I've pushed up a few more changes to handle some edge cases. You signed in with another tab or window. If it applies to all sway files, should we make space check bypass default for all swap files? Isn#t this a btrfs interface issue? You can always update your selection by clicking Cookie Preferences at the bottom of the page. The related discussion to get the physical offset of Btrfs swapfile is in https://bugzilla.kernel.org/show_bug.cgi?id=202803. 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. Even in the single device case, we make use of the virtual offsets to simplify block allocation. Thanks for the explanation. Don't be so generous with your sudo. @diabonas ahhh, yes. As descibred in Arch's Wiki Power management#Sleep hooks, you can create a systemd service that is triggered by the sleep service. Based on the wiki instructions, I came up with the following: Nicoadamo 16:09, 10 November 2019 (UTC) Does systemctl suspend-then-hibernate not work for you? Curious booted Hydrogen iso on usb and tried it there, nope, same thing. 241.7, Expected behaviour you didn't see 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. systemd version the issue has been seen with. I thought it is just swap file size should be larger than image size. Yes, as @helloworld1 said, Btrfs gives you a virtual device number for stat and a virtual offset for fiemap by design. Sorry I wasn't clearer about that before. We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. 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. It does not check for /sys/power/resume or inspect resume= kernel cmdline. Verified swap file works and has enough space. I'm not sure if Linux uses swap partition to hibernate. a) Wait for btrfs to change till this magically starts working? 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). For more information, see our Privacy Statement. 2. 3. 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. Current status: neither resume, nor resume_offset gets detected properly, yet systemd will override both. It needs to be in both. @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. 239.300-1. Unexpected behaviour you saw. 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. Otherwise, I will pick this back up over the weekend. 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). I think this is by design for Btrfs since it can handle multiple storage devices. Learn more. Elevated privileges should be given sparingly. they're used to log you in. I will happily provide any additional info you need, just let me know. sudo apt install hibernate It will install hibernate and other dependencies which are needed to hibernate. to your account, systemd version the issue has been seen with So we can't match the entries in /proc/swaps with resume and resume_offset and can't find the space in use. To start using this function you need to create a file. Pressing ALT and then clicking on the pause button just suspends, not hibernate, the system. 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. 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. Learn more, systemctl hibernate does not hibernate on swapfile on Btrfs after kernel 5.0. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Suspend and Hibernate do not Work - Should I report bug? I submitted #12760 which solves the general issue of ignoring the resume_offset by implementing d) in @Snoop05's list above. 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. Sign in Though these interfaces can be used directly, it is advisable to use some of high level interfacesto suspend/hibernate. Gnome Shell extension that adds a hibernate/hybrid suspend button in Status menu. Just tested your patch and the hibernate works great on system with unencrypted BTRFS and a single physical drive. 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. This operation is much faster than restoring the state from hibernation since the system state was not saved on the hard disk. However when I try to recover it immediately shows a black screen and stops there. How reproducible: Not sure. Or do you have any better ideas? Or we currently parse sleep.conf multiple times, which sucks too. @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. After some googling i still found no answer. Used distribution. Unfortunately, this did NOT work for me :- to your account. b) Implement btrfs swapfile support on systemd side? Successfully merging a pull request may close this issue. Successfully merging a pull request may close this issue. Expected behaviour you didn't see. I think there are a few more kinks to work out in this patch. 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 . 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. We’ll occasionally send you account related emails. ExecStart=/bin/systemctl … 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. If it finds a value > 0 will assume that was set previously and return without any offset calculation or resume device override. The line looks like this. Hope this should not be the case in the final patch since it clearly breaks existing setup. 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. 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. Actual results: System tries to hibernate and does not show an error message if … Already on GitHub? The route I took is fairly simple but I think it serves the purpose. You should be able to do that with systemctl edit systemd-logind.service. I am have applied the patch to 244 and testing it today. If you are in a local systemd-logind user session and no other session is active, the following commands will work without root privileges. Sign in 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. By clicking “Sign up for GitHub”, you agree to our terms of service and We use essential cookies to perform essential website functions, e.g. system should hibernate. gnome-shell-extension-hibernate-status. Use Cinnamon (for example). 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. FAQ Hibernation does not work. Apparantly on Btrfs even the device ID from fstat does not match the actual device ID, so the quick fix above should read. Hmm, so why does btrfs not follow the same APIs as other file systems on this? We use essential cookies to perform essential website functions, e.g. Unfortunately the latest patch does not work. 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. Hibernation might not work. Again, I haven't had a chance to setup my test environment for this but will a bit later today or tomorrow. I have been affected by this bug as well, like @helloworld1, I use a swapfile. 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 … c) Rewrite this component from scratch? The sleep code could generally use some love though. Steps to Reproduce: 1. Since Btrfs is using virtual physical offset of the file. Victor Paul December 10, 2018 at 8:47 am. Actual results: not hibernating Expected results: hibernate … The current logic in sleep.c does not get the correct physical offset of the file. It's not specific to Btrfs. Then I ran sudo systemctl start protonvpn-restart.service && sudo systemctl enable protonvpn-restart.service. 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. Have a question about this project? For more information, see our Privacy Statement. https://github.com/systemd/systemd/blob/master/src/shared/sleep-config.c#L436. Why does it works in version 243? I believe you'll need to reboot after making that change. And yes, SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK will apply in all cases - regardless of file system. But sudo systemctl hibernate was not working. I was finally able to test these changes on a VM. There has been the ability to bypass this check for some time so you'll need to use that here. It basically means when the hibernate image is written to disk, shutdown. Just report back the latest patch works great on my system. Would love to simply remove the previous code then and just use the new API.
