Looks like you invented your own hyperconverge solution. The NFS server on the node will always be accessible on the node, but if it is not accessible from other hosts, the entire DC may go down. Also you probably don't have any redundancy, so failure of single node cause downtime and data loss. Did you consider hyperconverge Gluster based setup? https://ovirt.org/documentation/gluster-hyperconverged/Gluster_Hyperconverged_Guide/ > We currently have a huge problem on our cluster, and export VM as OVA > takes lot's of time. > The huge problem is slow export to OVA or there is another problem? > I checked on the NFS storage, and it looks like there's files who might > be OVA in the images directory, I don't know the ova export code, but I'm sure it does not save in the images directory. It probably creates temporary volume for preparing and storing the exported ova file.

If you mean importing all vms and disks on storage to a new engine, yest, it should work.

Can you give more details on this problem? Please also specify oVirt version you use. Nir
