Hi

I have recently had a problem with my server: all writes to RAID drives were frozen and I had to force-reboot it. I looked at kernel logs and I think dm-integrity might be source of the problem. Could anyone help me understand meaning of following messages (this message was repeated 8 times, full kernel log is here: https://pastebin.com/DMgMtNJq <https://pastebin.com/DMgMtNJq> ):

Mar  1 23:48:21 unassigned-hostname kernel: [369732.498048] INFO: task kworker/0:112:26760 blocked for more than 120 seconds.

Is this a bug in kernel or do I have some problems with hardware?

Regards
Victor
