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=rbfailed to
init zonegroup: (2) No such file or directory2016-12-06

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

.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?
