Hi all,
I'm testing ovirt+glusterfs with only two node for all (engine,
glusterfs, hypervisors), on centos 6.5 hosts following guide at:
http://community.redhat.com/blog/2013/09/up-and-running-with-ovirt-3-3/
http://www.gluster.org/2013/09/ovirt-3-3-glusterized/
but with some change like setting on glusterfs, parameter
cluster.server-quorum-ratio to 50% (due to prevent glusterfs to go down
if one node goes done) and option on /etc/glusterfs/glusterd.vol "option
base-port 50152" (due to libvirt port conflict).
So, with the above parameter I was able to stop/reboot node not used to
directly mount glusterfs (eg lovhm002), but when I stop/reboot node,
that is used to mount glusterfs (eg node lovhm001), all data center goes
done, especially when I stop service glusterfsd (not glusterd
service!!!), but the glusterfs still alive and is reachable on node
lovhm002 that survives but ovirt/libvirt marks DC/storage in error.
Do you have any ideas to configure DC/Cluster on ovirt that remains
aware if node used to mount glusterfs goes down?
This is a sample vdsmd.log on node that remains on-line (lovhm002) when
I stopped services glusterd and glusterfsd node lovhm001:
