Hello, >> I'm doing some tests on the radosgw on luminous (12.2.1), I have a few questions. >> >> In the documentation[1], there is a reference to "radosgw-admin region get" but it seems not to be available anymore. >> It should be "radosgw-admin zonegroup get" I guess. >> >> 1. http://docs.ceph.com/docs/luminous/install/install-ceph-gateway/ >> >> I have installed my luminous cluster with ceph-ansible playbook. >> >> but when I try to manipulate zonegroup or zone, I have this >> >>> # radosgw-admin zonegroup get >>> failed to init zonegroup: (2) No such file or directory > > try with --rgw-zonegroup=default > >>> # radosgw-admin zone get >>> unable to initialize zone: (2) No such file or directory > > try with --rgw-zone=default > >> I guessed it's because I don't have a realm set and not default zone and zonegroup ? > > The default zone and zonegroup are part of the realm so without a > realm you cannot set them as defaults. > This means you have to specifiy --rgw-zonegroup=default and --rgw-zone=default > I am guessing our documentation needs updating :( > I think we can improve our behavior and make those command works > without a realm , i.e return the default zonegroup and zone.

I did that : # radosgw-admin realm create --rgw-realm=default --default { "id": "b5cc8a8e-bd96-4b19-8cdd-e87a58ed518a", "name": "default", "current_period": "e7bfcb5a-829b-418f-ae26-d6573a5cc8b9", "epoch": 2 } # radosgw-admin zonegroup modify --realm-id=b5cc8a8e-bd96-4b19-8cdd-e87a58ed518a --rgw-zonegroup=default --default # radosgw-admin zone modify --realm-id=b5cc8a8e-bd96-4b19-8cdd-e87a58ed518a --rgw-zone=default --default # radosgw-admin period update --commit and it works now, I can edit zone and zonegroup :) >> On the "default" zonegroup (which is not set as default), the "bucket_index_max_shards" is set to "0", can I modify it without reaml ? >> > I just updated this section in this pr: https://github.com/ceph/ceph/pull/18063 as discuss on irc, I did that but found on a bug : # radosgw-admin bucket reshard process --bucket image-net --num-shards=150 => http://tracker.ceph.com/issues/21619 Thanks, Best regards, -- Yoann Moulin EPFL IC-IT _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
