Yes, its possible.

I failed to interpret  'mount point' here. If you are talking about 'gluster' volume server , the VM behaviour depends on the gluster configuration which indirectly depend on the quorum configuration and volume configuration. If there is an error from underlying storage ( here gluster volume) VM can pause , however latest versions of ovirt support auto resume.

If you are using local data center the VM migration can't happen. You have to configure a storage domain which can be accessed from your Ovirt Cluster  Hosts .

Please have a look at http://www.ovirt.org/Gluster_Storage_Domain_Reference which talks about the recommended way of configuring it.

Hi Punit,


If you are using gluster volume for virt store, it is always recommend to enable /considering virt store use case mentioned here : http://gluster.org/documentation/use_cases/Virt-store-usecase/

Regarding how to add bricks to the volume , you can refer # https://access.redhat.com/documentation/en-US/Red_Hat_Storage/2.1/html/Administration_Guide/sect-User_Guide-Managing_Volumes-Expanding.html

The virt store use case enables quorum which ideally resolves the possibilities of split brain. 

Please feel free to revert if you come across any issues.

Hi,

I have 4 node GlusterFS Distributed Replicate volume...the same 4 host node i am using for compute purpose....now i want to make it HA....so if any host goes down .....VM will not pause and it will migrate to another available node...

1. Can any one have any document or reference to do this with keepalived...
2. I have one more node as spare...so if any host goes down and can not come up again because of any HW failure...i can add it...but i didn't find any way to add these bricks to volume...??

Thanks,
Punit
