Could you try to extract some error or warning > messages from system journal? (resend as I replied only to Vyacheslav) If by journals you mean logs then no. I'm only able to find some like this: Jul 3 10:32:45 wloczykij nilfs_cleanerd[1434]: resume (clean check) Jul 3 10:41:37 wloczykij nilfs_cleanerd[1434]: pause (clean check) That's all about nilfs in the last week and current log has only manual runs related to those operation described before.
