But, file system of "this volume" once in a while goes "read only" mode.

there will be log entries about this. Do a *forced* fsck.

Kai, thank you very much for the hint.

I am not sure which other log file has entries about this problem but here is the relevant section of dmesg:

What is the best way to run fsck on a production system?

Thank you
Mufit
