Andrew, RGW dynamic resharding is enabling via `rgw_dynamic_resharding` and ruled by `rgw_max_objs_per_shard`.Hello, I am have been managing a ceph cluster running 12.2.11. This was running 12.2.5 until the recent upgrade three months ago. We build another cluster running 13.2.5 and synced the data between clusters and now would like to run primarily off the 13.2.5 cluster. The data is all S3 buckets. There are 15 buckets with more than 1 million objects in them. I attempted to start sharding on the bucket indexes by using the following process from the documentation. Pulling the zonegroup #radosgw-admin zonegroup get > zonegroup.json Changing bucket_index_max_shards to a number other than 0 and then #radosgw-admin zonegroup set < zonegroup.json Update the period This had no effect on existing buckets. What is the methodology to enable sharding on existing buckets. Also I am not able to see the reshard list I get the follwoing error. 2019-04-10 10:33:05.074 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000000 2019-04-10 10:33:05.078 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000001 2019-04-10 10:33:05.082 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000002 2019-04-10 10:33:05.082 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000003 2019-04-10 10:33:05.114 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000004 2019-04-10 10:33:05.118 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000005 2019-04-10 10:33:05.118 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000006 2019-04-10 10:33:05.122 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000007 2019-04-10 10:33:05.122 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000008 2019-04-10 10:33:05.122 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000009 2019-04-10 10:33:05.122 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000010 2019-04-10 10:33:05.126 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000011 2019-04-10 10:33:05.126 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000012 2019-04-10 10:33:05.126 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000013 2019-04-10 10:33:05.126 7fbd534cb300 -1 ERROR: failed to list reshard log entries, oid=reshard.0000000014 Any suggestions Or you may reshard bucket by hand via `radosgw-admin reshard add ...`.
