Hi Fernando, I see each host has direct connection nfs mount, but yes, if main host to which I connected nfs storage going down the storage becomes unavailable and all vms are down

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.

Well, make it not go through host1 and dedicate a storage server for running NFS and make both hosts connect to it. 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
