Description Avi Avraham 2019-12-08 14:18:06 UTC 
Description of problem:
There is a bucket that contains 2 Million objects, dynamic resharding is enabled, obj threshold for resharding is not defined (so it is 100K).
The error when running radosgw-admin reshard add --bucket=check_dynamic --num-shards=2:
ERROR: failed to list reshard log entries, oid=reshard.0000000000
ERROR: failed to list reshard log entries, oid=reshard.0000000001
ERROR: failed to list reshard log entries, oid=reshard.0000000002
...
ERROR: failed to list reshard log entries, oid=reshard.0000000015 

Version-Release number of selected component (if applicable):
3.3z1

How reproducible:


Steps to Reproduce:
radosgw-admin reshard list --bucket=check_dynamic --num-shards=4 --debug-rgw=20 --rgw-zone=default

Actual results:
Command failed with the following error:
Add Resharding is disabled

Expected results:
dynamic resharding will successfully run.

Additional info:
The problem, as indicated by Or Fridman from the consulting team, seems to have been that we did not have a default realm set (`radosgw-admin realm list` showed an empty list under `realms`).
After modifying the zonegroup to the right realm id and then update period, after those dynamic resharding start to work.
