Hi,
this is not necessarily but most likely a hint to a (slowly) failing
disk. Check all OSDs for this PG for disk errors in dmesg and smartctl.

There's no guarantee that new disks can't be faulty. We had this last
year when we expanded our cluster with brand new servers and disks,
one of the new OSDs failed almost immediately.
You can wait and see how often this appears and if it's always the
same disk. Just keep it in mind.

Note that in this case the inconsistencies are not coming from object
reads, but from comparing the omap digests of an rgw index shard.
This seems to be a result of a replication issue sometime in the past
on this cluster.

Interesting, your comment implies that it is a replication issue, which
does not stem from a faulty disk. But, couldn't the disk have a bit
flip? Or would you argue that would've shown as a disk read error
somewhere (because of ECC on the disk.)

In my experience inconsistencies caused by IO errors always have a
SCSI Medium Error showing up in the kernel logs. (dmesg, journalctl
-k, /v/l/messages, ...)
(Except in the case of one very bad non-enterprise SMR drive I run at
home, not at work).
