Ceph Radosgw Upgrade

Well well well…

What’s going on here? #

So, I was updating Ceph to Reef1, on our ProxMox cluster, and stubbed my toe again.

This Looks… Familiar… #

I was pretty sure I’d fixed this before, an so it was a simple matter of remembering wth I did…

Fortunately I wrote it up! So it was a pretty quick fix..

Essentially the ExecStart line in /lib/systemd/system/ceph-radosgw@.service needed a little massaging.

ExecStart=/usr/bin/radosgw -f --cluster ${CLUSTER} --name client.%i --setuser ceph --setgroup ceph

It needed to change to:

ExecStart=/usr/bin/radosgw -f --setuser ceph --setgroup ceph --cluster ${CLUSTER} --name client.radosgw.%i --keyring=/etc/ceph/ceph.client.radosgw.keyring

Validating #

root@pxm4:~# systemctl daemon-reload
root@pxm4:~# systemctl restart ceph-radosgw@`hostname`.service; journalctl -fu ceph-radosgw@`hostname`.service
...Aaaaand We're back!
