TUMBLEWEED Hibernate and file systems issue

Hibernate and file systems issue

Hello,

If I initiate hibernate either from the menu or by running

Code:

systemctl hibernate

after the Tumbleweed wakes ups it does not have all the file systems mounted. I found it because I started having issues with apache2 which started reporting that /srv/www/htdocs cannot be found.

After a fresh start:

Code:

Filesystem Size Used Avail Use% Mounted on devtmpfs 3.9G 0 3.9G 0% /dev tmpfs 3.9G 0 3.9G 0% /dev/shm tmpfs 3.9G 9.9M 3.9G 1% /run tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/sda2 236G 8.9G 227G 4% / tmpfs 3.9G 8.0K 3.9G 1% /tmp /dev/sda2 236G 8.9G 227G 4% /boot/grub2/i386-pc /dev/sda2 236G 8.9G 227G 4% /boot/grub2/x86_64-efi /dev/sda2 236G 8.9G 227G 4% /opt /dev/sda2 236G 8.9G 227G 4% /home /dev/sda2 236G 8.9G 227G 4% /srv /dev/sda2 236G 8.9G 227G 4% /root /dev/sda2 236G 8.9G 227G 4% /var /dev/sda2 236G 8.9G 227G 4% /.snapshots /dev/sda2 236G 8.9G 227G 4% /usr/local /dev/sda1 511M 74M 438M 15% /boot/efi tmpfs 785M 16K 785M 1% /run/user/1000

After hibernate:

Code:

Filesystem Size Used Avail Use% Mounted on devtmpfs 3.9G 0 3.9G 0% /dev tmpfs 3.9G 0 3.9G 0% /dev/shm tmpfs 3.9G 18M 3.9G 1% /run tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/sda2 236G 8.9G 227G 4% / tmpfs 3.9G 8.0K 3.9G 1% /tmp /dev/sda2 236G 8.9G 227G 4% /var /dev/sda2 236G 8.9G 227G 4% /home tmpfs 785M 16K 785M 1% /run/user/1000

Certainly, running

Code:

sudo mount -a

fixes the problem however I would like the OS to take care of it. I do not think the issue is related to the hardware configuration.

This behavior is on my physical machine. In a VirtualBox the Tumbleweed either crashes when entering my password after waking up or it starts like a fresh boot.

The OS's on both machines are with latest updates applied.

While the Tumbleweed in the VM may not be so important to me I would like to have a guaranteed and correct state after hibernate on my hardware machine.

Any ideas how to fix it?

Thank you and have a good day.

Re: Hibernate and file systems issue

When the system wakes up from hibernation, everything should be mounted. That's because hibernation makes a memory record of the system state, and wake up should recover that state.

There was a bug, a while back, where systemd mount units would unmount some file systems or "btrfs" subvolumes. I'm guessing that might be happening to you.

Personally, I don't use "btrfs". So I don't have any experience that might help.

Re: Hibernate and file systems issue

This was a recurring problem around February-March, I described it here: https://forums.opensuse.org/showthre...35#post2928735

Except, I don't recall seeing the issue after resuming from hibernation, but from cold start, every once in a while.

Things to do:

Check out `journalctl -b -p 0..4`;
Attempt to disable btrfsmaintenance (if is the original problem re-emerging): https://en.opensuse.org/SDB:Fix_btrf...enance-refresh

Mind you this workaround might help but might be a different issue. I guess the journal can give you clues.

Re: Hibernate and file systems issue

Thank you very much for your replies and help.

It looks like the problem is related to btrfs. I've never used it before and decided to give it a try. I will switch to ext4 which I am more familiar with.

It is very clear it has something to do with Btrfs. All the Btrfs subvolumes are missing and all others are there.
