You need to setup a virtual IP to use as the mount point, most people =
use keepalived to provide a virtual ip via vrrp for this. Setup =
something like 10.10.10.10 and use that for your mounts.
Right now, if 10.10.10.2 goes away, all your gluster mounts go away and =
your VMs get paused because the hypervisors can=92t access the storage. =
Your gluster storage is still fine, but ovirt can=92t talk to it because =
10.10.10.2 isn=92t there.
If the SPM goes down, it the other hypervisor hosts will elect a new one =
(under control of the ovirt engine).
Same scenarios if storage & compute are on the same server, you still =
need a vip address for the storage portion to serve as the mount point =
so it=92s not dependent on any one server.

Hi,

I have some HA related concern about glusterfs with Ovirt...let say i =
have 4
storage node with gluster bricks as below :-=20
=20
1. 10.10.10.1 to 10.10.10.4 with 2 bricks each and i have distributed =
replicated
architecture...
2. Now attached this gluster storge to ovrit-engine with the
following =
mount point 10.10.10.2/vol1
3. In my cluster i have 3 hypervisior hosts (10.10.10.5 to
10.10.10.7) =
SPM is on 10.10.10.5...
4. What happen if 10.10.10.2 will goes down.....can hypervisior host
=
can still access the storage ??
5. What happen if SPM goes down ???
=20
Note :- What happen for point 4 &5 ,If storage and Compute both =
working on
the same server.
=20
Thanks,
Punit=20
