[ovirt-users] Re: Ovirt hypervisor as an DRBD node

Hi community,
I would like to use 3 nodes for hypervisor (hosted engine or install a
separate VM with engine for its subsequent management) to use them as
storage nodes - drbd 9 dual primary + quorum node (aka backup), ocfs 2 - so
that the VMs used the hardware of both nodes (so to speak, hyperconverged
with drbd). Can you tell me if there are any limits on the part of ovirt
for this configuration and the best way to mount ocfs2 - iscsi via scst,
posixFS or cinder?
I would not expect an issue as long as you expose the storage with
supported storage types (iSCSI, NFS, etc). I guess though that you need to
separately manage the HA part of the storage (pacemaker comes to my mind)
which complicates the setup, whereas if going with glusterFS this is done
automatically from oVirt by using the backup-volfile-servers gluster mount
option.
Thanks in advance
Best regards
