--- Comment #2 from Ulrich.Windl (Ulrich.Windl@...uni-regensburg.de) ---
Having a second look, it seems the first error was concurrently with fstrim, so
possibly fstrim can play a role in the scenario:
kernel: print_req_error: I/O error, dev xvdb, sector 29730024
fstrim[8864]: fstrim: /var: FITRIM ioctl failed: Input/output error
fstrim[8864]: fstrim: /tmp: FITRIM ioctl failed: Input/output error
...
(the final message was like 13 minutes after those above)
