Hi there!
Does anyone else have an idea what I could do to get rid of this error?
BTW: it is the third time that the pg 20.0 is gone inconsistent.
This is a pg from the metadata pool (cephfs).
May this be related anyhow?
# ceph health detail
HEALTH_ERR 1 MDSs report damaged metadata; 1 scrub errors; Possible data damage: 1 pg inconsistent
MDS_DAMAGE 1 MDSs report damaged metadata
mdsmds3(mds.0): Metadata damage detected
OSD_SCRUB_ERRORS 1 scrub errors
PG_DAMAGED Possible data damage: 1 pg inconsistent
pg 20.0 is active+clean+inconsistent, acting [9,27,15]
Best regards,
Lars
