Weird messages in syslog

hidalgo · Apr 2, 2018

After repairing and expanding my ceph cluster, I found some weird messages I couldn’t find any information about. What do they mean?

Code:

Check in the ceph logs ('/var/log/ceph/'), there should be more information on it. But it looks like, as the scrubbing found some inconsistencies.
