Are you trying to reshard a bucket in a multisite setup? That isn't
expected to work (and, IIRC, the changes to support doing so aren't
going to make it into quincy).

Hi,

No, Only one cluster, some replication, but with rclone.

But, I have created one zonegroup and a zone.
Even though, it was working until we face the LARGE OMAP.
resharding has worked because, we have 29 shard already.

Perhaps some news in this related Bug : https://tracker.ceph.com/issues/53856
Hope it will be backported to Octopus.


Description
When "bucket index list" traverses the different regions in the bucket index assembling the output, it miscalculates how many entries to ask for at one point.
This fixes previous "rgw: bucket index list can produce I/O errors".

Credit for finding this bug goes to Soumya Koduri <skoduri@xxxxxxxxxx>.
