Hello Eugen,

I remember one of our customers reporting inconsistent objects on a
regular basis although no hardware issues were detectable. They
replicate between two sites, too. A couple of months ago both sites
were updated to the same exact ceph minor version (also Octopus), they
haven't faced inconsistencies since then. I don't have details about
the ceph version(s) though, only that both sites were initially
installed with Octopus. Maybe it's worth checking your versions?
Yes, everything has the same version:

"overall": {
"ceph version 15.2.15
(2dfb18841cfecc2f7eb7eb2afd65986ca4d95985) octopus (stable)": 34
}
}
I just observed another 3 scrub errors. Strangely they never see to have
occurred on the same pgs again.
I shall be running another deep scrub on those OSD again to narrow this
down.
But I am somewhat suspecting this to be a potential issue with the OMAP
validation part of the scrubbing.
For RADOSGW there are large OMAP structures with lots of movement. And
the issues only are with the metadata pools.
Regards
Christian
