Hi,
oh, so you have only 2 physical servers? I've understood they were 3! Well, i=
n this case ceph would not work very well, too few resources and redundancy.=
You could try a replica 2, but it's not safe. Having a replica 3 could be f=
orced, but you would end up with a server with 2 replicas, which is dangerou=
s/useless.
Okay, so you use nfs as storage domain, but in your setup the HA is not guar=
anteed: if a physical machine goes down and it's the one where the storage d=
omain resides you are lost. Why not using gluster instead of nfs for the ovi=
rt disks? You can still reserve a small gluster space for the non-ceph machi=
nes (for example a cinder VM) and ceph for the rest. Where do you have your c=
inder running?
Cheers,
Alessandro

Hi Alessandro,
=20
Right now I have 2 physical server where I have host ovirt these are HP pr=
oliant
dl 380 each server 1*500GB SAS & 1TB *4 SAS Disk and 1*500GB SSD. So=
right now I have use only one disk which 500GB of SAS for my ovirt to run o=
n both server. rest are not in use. At present I am using NFS which coming f=
rom mapper to ovirt as storage, go forward we like to use all these disk as =
hyper-converged for ovirt. RH I could see there is KB for using gluster. Bu=
t we are looking for Ceph bcoz best pref romance and scale.
