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.)

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.

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.
