[Gluster-users] Need help for production setup

[Punit Dambiwal]

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. 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 ???

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

Thanks,
Punit
