Hi Vijay,

Thanks for the updates..that means if we use replica=3...then there is no
need to user HW raid ??

As i want to use it with Ovirt with HA....would you mind to let me know how
i can achieve this ??

I have some HA related concern about glusterfs with Ovirt...let say i have
4 storage node with gluster bricks as below :-

1. to with 2 bricks each and i have distributed
replicated architecture...
2. Now attached this gluster storge to ovrit-engine with the following
mount point
3. In my cluster i have 3 hypervisior hosts ( to SPM
is on
4. What happen if will goes down.....can hypervisior host can
still access the storage ??
5. What happen if SPM goes down ???

Note :- What happen for point 4 &5 ,If storage and Compute both working on
the same server.
