Are you running a multi-site setup? In this case it's best to set the default shard size to large enough number *before* enabling multi-site. If you didn't do this: well... I think the only way is still to completely re-sync the second site... Paul -- Paul Emmerich Looking for help with your Ceph cluster?

I found information that suggests that, for older versions of Ceph, buckets couldn't be sharded after creation[1]. Other information suggests the Nautilus (which we are running), can re-shard dynamically, but not when multi-site replication is configured[2]. > > This suggests that a "manual" resharding of a Nautilus cluster should be possible, but I can't find the commands to do it. Has anyone done this? Does anyone have the commands to do it? I can schedule down time for the cluster, and take the RADOSGW instance(s), and dependent user services offline. > > [1]: https://ceph.io/geen-categorie/radosgw-big-index/ > [2]: https://docs.ceph.com/docs/master/radosgw/dynamicresharding/ > > Thank you, > > Dominic L.
