Hi, =20 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 _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
