Hello, running Ceph Nautilus 14.2.4, we encountered this documented dynamic resharding issue: http://lists.ceph.com/pipermail/ceph-users-ceph.com/2019-November/037531.ht… We disabled dynamic resharding in the configuration, and attempted to reshard to 1 shard: # radosgw-admin reshard add --bucket files --num-shards 1 --yes-i-really-mean-it However, it achieved nothing, and the bucket is now stuck in resharding status. It is impossible to clear the resharding flag (I have tried the bucket check --fix operation with no avail) # radosgw-admin reshard cancel --bucket=files 2020-04-28 11:47:18.721 7fd213b969c0 -1 ERROR: failed to remove entry from reshard log, oid=reshard.0000000000 tenant= bucket=files # radosgw-admin bucket reshard --bucket files --num-shards 1 ERROR: the bucket is currently undergoing resharding and cannot be added to the reshard list at this time
