Error in system logs

sluggo · 29. Mai 2017

I'm getting the following messages (by the thousands) in my system log:

Code

May 28 15:06:19 openmediavault kernel: [462550.598892] end_request: I/O error, dev sdf, sector 2070
May 28 15:06:19 openmediavault kernel: [462550.598896] sd 5:0:0:0: [sdf] Unhandled error code

Attached is my boot log. OMV had problems booting. I've tried looking at my SMART log but I'm not clear on what it's telling me... Normally when a drive goes bad it becomes obvious but I can't figure out what's going with my system. The boot log says drive 4 died (I think that's sdf), which is a parity drive for SnapRaid. SMART log doesn't really say anything about the drive being dead, but then again I don't know where/how SMART logs would even say that.

thanks

Can you post the smart data for the drive.

smartctl -a /dev/sdf
By the way looking at your log seems you're using a very old openmediavault version.

I'm running 2.2.13, which is only one release behind the most current 2.2.14 I think?

I saw this line

/etc/apache2/openmediavault-webgui.d/default.conf

i guess this install comes from 0.5 or earlier.

If the command above is not responding then yes i guess the disk is dead.

Try

smartctl -a -T permissive /dev/sdf

If the disk is dead, I wish that smartctl would just say something like "your disk is dead". The boot log is maybe the most informative, telling me that Disk4 has errors and fsck fails.

subzero79 · 30. Mai 2017

Well if smartctl cannot send commands to the disk not much can do there. If smart and notifications are enabled you should get relevant messages on certain smart attributes relevant to the disk health (like bad sectors and reallocated ones ).

How old is the disk btw?

subzero79 · 30. Mai 2017

also smart doesn't say your disk is dead it just retrieves smart data. Omv has a health indicator that is based on certain critical attributes. However this feature I cannot remember if it was backported to 2.0.

I think the disk is max 3 years old. Likely closer to two.
