Seems like this sharding we need to be plan carefully since the beginning. I'm thinking to set the shard number by default to the maximum which is 64k and leave it as is so we will never reach the limit only if we reach the maximum number of objects. Would be interesting to know what is the side effect if I set the shards to 64k by default.

Hey Timothy,
Did you ever resolve this issue, and if so, how?
Unfortunately, I was never able to resolve it; the bucket(s) in question had to be recreated and then removed.
Thank you..I looked through both logs and noticed this in the cancel one:
osd_op(unknown.0.0:4164 41.2 41:55b0279d:reshard::reshard.0000000009:head [call rgw.reshard_remove] snapc 0=[] ondisk+write+known_if_redirected e24984) v8 -- 0x7fe9b3625710 con 0 osd_op_reply(4164 reshard.0000000009 [call] v24984'105796943 uv105796922 ondisk = -2 ((2) No such file or directory)) v8 ==== 162+0+0 (203651653 0 0) 0x7fe9880044a0 con 0x7fe9b3625b70 ERROR: failed to remove entry from reshard log, oid=reshard.0000000009 tenant= bucket=foo
Is there anything else that I should look for? It looks like the cancel process thinks that reshard.0000000009 is present (and probably blocking my attempts at resharding) but it's not actually there and thus can't be removed.
