If this works in this way then it's a huge downside in the architecture.
Perhaps someone can clarify in more details.

Hello Konstantin.
That doesn`t make much sense make a whole cluster depend on a
single host. From what I know any host talk directly to NFS
Storage Array or whatever other Shared Storage you have.
Have you tested that host going down if that affects the other
with the NFS mounted directlly in a NFS Storage array ?

In ovirt you have to attach storage through specific host.
If host goes down storage is not available.

In my view NFS is much easier to manage than any other
type of storage, specially FC and iSCSI and performance is
pretty much the same, so you won`t get better results
other than management going to other type.

Hi guys,
I have one nfs storage,
it's connected through host1.
host2 also has access to it, I can easily migrate
vms between them.
The question is - if host1 is down - all
infrastructure is down, since all traffic goes through
host1,
is there any way in oVirt to use redundant storage?
Only glusterfs?
Thanks
