Hello, Ceph users,
TL;DR: radosgw fails on me with the following message:
2019-01-17 09:34:45.247721 7f52722b3dc0 0 rgw_init_ioctx ERROR: librados::Rados::pool_create returned (34) Numerical result out of range (this can be due to a pool or placement group misconfiguration, e.g. pg_num < pgp_num or mon_max_pg_per_osd exceeded)
Detailed description:
I have a Ceph cluster installed long time ago as firefly on CentOS 7,
and now running luminous. So far I have used it for RBD pools, but now
I want to try using radosgw as well.
I tried to deploy radosgw using
# ceph-deploy rgw create myhost
Which went well until it tried to start it up:
[myhost][INFO ] Running command: service ceph-radosgw start
[myhost][WARNIN] Redirecting to /bin/systemctl start ceph-radosgw.service
[myhost][WARNIN] Failed to start ceph-radosgw.service: Unit not found.
[myhost][ERROR ] RuntimeError: command returned non-zero exit status: 5
[ceph_deploy.rgw][ERROR ] Failed to execute command: service ceph-radosgw start
[ceph_deploy][ERROR ] GenericError: Failed to create 1 RGWs
Comparing it to my testing deployment of mimic, where radosgw works,
the problem was with the unit name, the correct way to start it up
apparently was
# systemctl start ceph-radosgw@rgw.myhost.service
Now it is apparently running:
/usr/bin/radosgw -f --cluster ceph --name client.rgw.myhost --setuser ceph --setgroup ceph
However, when I want to add the first user, radosgw-admin fails and
radosgw itself exits with the similar message:
# radosgw-admin user create --uid=kas --display-name="Jan Kasprzak"
2019-01-17 09:52:29.805828 7fea6cfd2dc0 0 rgw_init_ioctx ERROR: librados::Rados::pool_create returned (34) Numerical result out of range (this can be due to a pool or placement group misconfiguration, e.g. pg_num < pgp_num or mon_max_pg_per_osd exceeded)
2019-01-17 09:52:29.805957 7fea6cfd2dc0 -1 ERROR: failed to initialize watch: (34) Numerical result out of range
couldn't init storage provider
So I guess it is trying to create a pool for data, but it fails somehow.
Can I determine which pool it is and what parameters it tries to use?
I have looked at my testing mimic cluster, and radosgw there created the
following pools:
.rgw.root
default.rgw.control
default.rgw.meta
default.rgw.log
default.rgw.buckets.index
default.rgw.buckets.data
So I created these pools manually on my luminous cluster as well:
# ceph osd pool create .rgw.root 128
(repeat for all the above pool names)
Which helped, and I am able to create the user with radosgw-admin.
Now where should I look for the exact parameters radosgw is trying
to use when creating its pools?
Thanks,
-Yenya

This is the world we live in: the way to deal with computers is to google
the symptoms, and hope that you don't have to watch a video. --P. Zaitcev
