All;
We're backing to having large OMAP object warnings regarding our RGW index pool.
This cluster is now in production, so I can simply dump the buckets / pools and hope
everything works out.
I did some additional research on this issue, and it looks like I need to (re)shard the
bucket (index?). 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.
