Hi
I was configuring two realms in one cluster. After set up the second realm, I found a problem, the master zonegroup are set to a zonegroup "default" which is not what I want, here is current period of the second realm rb:
# radosgw-admin period get --rgw-realm=rb

As you can see, the master zone group is set to a zone group called "default", I want to remove this default zone group and let tsz be the master.
I tried a lot of ways, like modify "default" zone group to --master=false, remove "default" zone group from realm rb. But all these operations lead to one same result:
# radosgw-admin zonegroup remove --zonegroup-id=333fdf5f-5a34-457e-a988-608eba67659a --zone-id=2292245d-ab27-4a8c-b38d-b084e29fb5d5 --rgw-realm=rb
failed to init zonegroup: (2) No such file or directory

The zone group named "default" seems did not exists! It must has been deleted by me, I recheck this via zonegroup get command:
# radosgw-admin zonegroup get --rgw-realm=rb --zonegroup-id=333fdf5f-5a34-457e-a988-608eba67659a
failed to init zonegroup: (2) No such file or directory2016-12-06 13:19:59.344485 7fc77369e9c0 0 failed reading obj info from .rgw.root:zonegroup_info.333fdf5f-5a34-457e-a988-608eba67659a: (2) No such file or directory
How can I get rid of this ghost "default" zonegroup? Thanks.
PS: It's a little confusing and frustrated experience using radosgw-admin command, it's very hard to know what options are supported for sone sub-command, do you know is there any comprehensive reference of radosgw-admin?
