Hi Burkhard,
Zitat von Burkhard Linke <Burkhard.Linke@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>:
HI,
since the upgrade to luminous 12.2.2 the mons are complaining about
scrub errors:
2017-12-13 08:49:27.169184 mon.ceph-storage-03 [ERR] scrub mismatch
today two such messages turned up here, too, in a cluster upgraded to
12.2.2 over the weekend.

Ceph state remained the same even with this in the mon logs. It was
only in the logs of a single mon. I also checked the MDS log files,
nothing to be found there (and especially not at that time).
These errors might have been caused by problems setting up multi mds
after luminous upgrade.
we have only a single active MDS, plus one standby - so maybe it's
something different.
Regards,
J
