Hi all,
I created 3 clusters in unique datacenter. I installed my hosts to the
first one after activating the gluster service in the cluster tab. A
expected otopi installed then the vdsm-gluster rpm and everything were
ok for this first cluster.
The other ones weren't initially gluster ready and I wanted to activate
the service after installing the host (so they were without vdsm-gluster
package). But checking that item didn't do anything for these hosts, so
that I had to manually install vdsm-gluster package. Then, when creating
a volume, the UI told me that hosts couldn't communicate. So I had to
manually probe them. This leads me to that question : is it an expected
behaviour? The whole gluster job (installing appropriated package and
probing peers in the cluster) should be done thanks to the UI cluster
tab "gluster service".
A last question : why isn't it possible to probe host on different
clusters in the same datacenter, could be very useful.

- selecting the 'enable gluster service' in later stage(after the hosts
are added) doesn't do anything. As you said, this could be a nice
feature though.
- 'gluster peer probe' is used to form a logical cluster. I don't think
having the hosts from different clusters to form a gluster-cluster is
the right way.
Thanks,
Kanagaraj

After checking the checkbox
for gluster services you'll need to migrated
all vms from a host and put it into maintenance then use the re-install
link and the needed packages will be downloaded and installed and a peer
probe will be done. After that reactivate the host and proceed to the
next one. One caveat found: chkconfig glusterd on isn't executed. You'll
need to do that by hand and also start the service or restart the server
while in maintenance mode.
