In my openSUSE 13.1 system, I have / and /home on separate partitions
of a two disk btrfs raid1 array.
# btrfs fi sh
Label: system uuid: 0b07b829-9a0e-44ab-89ee-14b36a45199e
Total devices 2 FS bytes used 11.99GiB
devid 1 size 40.00GiB used 16.04GiB path /dev/sda2
devid 2 size 40.01GiB used 16.03GiB path /dev/sdb2
Label: home uuid: 56884b1d-93ab-4db9-bc93-eff3833e91e1
Total devices 2 FS bytes used 1.23TiB
devid 1 size 2.69TiB used 1.24TiB path /dev/sda3
devid 2 size 2.69TiB used 1.24TiB path /dev/sdb3
Once a week, I run a scrub on each of them, during the night. One
morning I found the computer locked, but on vt2 btrfs was churning out
error messages. Unfortunately, I can't remember what they said, and
didn't write them down (or photograph them).
SMART doesn't report any problems with the hardware.
When I run scrub on the root (system) partition now, I get
ERROR: scrub is already running.
To cancel use 'btrfs scrub cancel /'.
To see the status use 'btrfs scrub status [-d] /'.
# btrfs scrub cancel /
ERROR: scrub cancel failed on /: not running
and scrub status reports:
scrub status for 0b07b829-9a0e-44ab-89ee-14b36a45199e
scrub started at Tue Sep 30 01:00:01 2014, running for 300 seconds
total bytes scrubbed: 6.10GiB with 1284927 errors
error details: read=1284925 super=2
corrected errors: 192, uncorrectable errors: 1284729, unverified
This situation (scrub running persistently) survives reboots.
On the /home partition, everything is OK:
scrub status for 56884b1d-93ab-4db9-bc93-eff3833e91e1
scrub started at Tue Oct 14 02:00:01 2014 and finished after 9972 seconds
total bytes scrubbed: 2.47TiB with 0 errors
Should I worry about this (apart from the fact that I cannot scrub /)?
What can I do about it?
BTW. I know I'm running a rather old version of btrfs, but at the
moment I want to stick with the default kernel (3.11.10-21-desktop)
for openSUSE 13.1.
System: Linux 3.11.10-21-desktop
