Hi,
I'm currently exploring Pacific and the "_admin" label doesn't seem to
work as expected.
pacific1:~ # ceph -v
ceph version 16.2.3-26-g422932e923
(422932e923eb429b9e16c352a663968f4b6f0a52) pacific (stable)
According to the docs [1] the "_admin" label should instruct cephadm
to distribute a ceph.conf and the admin keyring to the labeled host:
_admin: Distribute client.admin and ceph.conf to this
host.
By default, an _admin label is applied to the first host in the
cluster (where bootstrap was originally run), and the client.admin
key is set to be distributed to that host via the ceph orch
client-keyring ... function. Adding this label to additional hosts
will normally cause cephadm to deploy config and keyring files in
/etc/ceph.
I can not confirm this, neither has the bootstrap node (pacific1) the
"_admin" label (but he has the ceph.conf and admin keyring) nor does
pacific2 have the admin keyring. Here's my host ls:
pacific1:~ # ceph orch host ls
HOST ADDR LABELS STATUS
pacific1 192.168.124.183 mon
pacific2 192.168.124.49 _admin mon
pacific5 192.168.124.63 mon
pacific1:~ # ssh pacific2 find /etc/ceph
/etc/ceph
/etc/ceph/rbdmap
pacific1:~ # find /etc/ceph/
/etc/ceph/
/etc/ceph/ceph.pub
/etc/ceph/ceph.conf
/etc/ceph/rbdmap
/etc/ceph/ceph.client.admin.keyring
I searched a bit on tracker.ceph.com but couldn't find an existing
issue. Is this worth a bug report?
Regards,
Eugen
