Hi all,
Hi Qu,
I am also getting this very same error on my system.
Actually, I am experiencing this since the following old bug was introduced AND
also even after it has been fixed:
https://lore.kernel.org/linux-btrfs/20190521190023.GA68070@glet/T/
That (dm-related) bug was claimed to have been fixed and users confirmed that
their btrfs partitions were working correctly again, but I am still
experiencing some issues from time to time - and obviously only on SSD devices.
Just to clarify: I am using btrfs volumes on encrypted LUKS partitions, where
every partition is encrypted individually.
I am *NOT* using LVM at all: just btrfs directly on top of LUKS (which is
different from the users' setup in the above-mentioned bug reports).
And I am trimming the partitions only via fstrim, have configured the mount
points with the "nodiscard" option and the LUKS volumes in /etc/crypttab with
"discard", so to have the pass-through when I use fstrim.
Opposite to Justin, my partitions are all aligned.
When this happens on my root partition, I cannot launch any command anymore
because the file system is not responding (e.g.: I get "ls: command not
found"). I cannot actually do anything in reality, because the system console
is flooded with messages like:
"sd <....> [sdX] tag#29 access beyond end of device"
and that "clogs" the system. Since the root fs is unusable, the system log
cannot store those messages, so I can't find them at the next reboot.
I can only soft-reset (CTRL-ALT-DEL), it's the "cleanest" (and only) way I can
get back to a working system.
When the system restarts, it takes 2 seconds longer than usual to mount the
file systems, and then I can use the PC again.
Immediately after login, if I run btrfs scrub, I get no errors (I scrub ALL of
my partitions: they're all fine). So, it seems that at least the auto-recovery
capability of btrfs works fine, thanks to you devs :-)
Then, if I boot from an external device and run btrfs check on the unmounted
file systems, it also reports NO errors - opposite to what was happening when
the dm bug was still open: to me, this really means that btrfs today is able to
heal itself from this issue (it was not always the case in 2019, when the dm
bug was opened).
I have not tried to boot from external device directly after this issue occurs
- I mean, performing btrfs check without going first through the btrfs scrub
step. I will do that next time and see what output I get.
All my partitions are snapshotted, and surely this could help with
auto-recovery.
What I have noticed is that when this bug happens, it ALWAYS happens after I
have purged the old snapshots: that is, when the root partition only has one
"fresh" (read-only) snapshot. This is never happening when I have more than one
snapshot - maybe it means nothing, but it seems to me to be systematic.
I have attached a file with my setup.
Could you maybe spot anything weird there? It looks fine to me. The USER and
SCRATCH volumes are in RAID-0.
I am unable to provide any dmesg output or system log because, as said, when it
happens it does not write anything to the SYS partition (where /var/log is). I
will move at least /var/log/journal to another device, so hopefully next time I
will be able to provide some useful info.
Another info: of course, I have tried (twice!) to reconstruct the system SSD
from scratch, because I wanted to be sure that it was not depending on some
exotic issue. And each time I used a brand new device.
So, this issue has been happening with a SanDisk Ultra II and with two
different Samsung EVO 860.
Is it possible that what we are experiencing is still an effect of that dm bug,
that it was not completely fixed?
Thanks for your help, and for reading till here :)
