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
2017-12-13 08:49:27.169203 mon.ceph-storage-03 [ERR] mon.0

2017-12-13 08:49:27.169216 mon.ceph-storage-03 [ERR] mon.1

2017-12-13 08:49:27.169229 mon.ceph-storage-03 [ERR] scrub mismatch
2017-12-13 08:49:27.169243 mon.ceph-storage-03 [ERR] mon.0

2017-12-13 08:49:27.176454 mon.ceph-storage-03 [ERR] mon.0
ScrubResult(keys {mgrstat=10,monmap=26,osd_metadata=64} crc
{mgrstat=3940483607,monmap=3662510285,osd_metadata=45209833})
2017-12-13 08:49:27.176472 mon.ceph-storage-03 [ERR] mon.1
ScrubResult(keys {mgrstat=10,monmap=26,osd_metadata=64} crc
{mgrstat=3940483607,monmap=3662510285,osd_metadata=289852700})
These errors might have been caused by problems setting up multi mds
after luminous upgrade.
OSD scrub errors are a well known problem with many available
solutions....but how do I fix mon scrub errors?
Best regards,
Burkhard
