Andrija,
Thanks for your answer, but I would think that if there is an issue with the
secondary storage it would also effect the template creation. I do not have any
issues with directly creating the templates. The issues seems to be when the
snapshots are involved.
Also, i've noticed that when you do root_volume > template > vm - the template
format in the database is shown as QCOW2. When I am doing root_volume >
snapshot > template > vm the template format is shown as RAW.
It seems that there is a problem using RAW format. Has anyone else encountered
this issue?

Make sure that hypervisor node, can mount and write to the storage, you can
check this with primary storage, there is KVMHA folders inside, and each of
them has files that should be modified each minute, so if any of those
lags, you might have issues with connecting to storage - I had that case,
so forced umount of the problematic NFS storage, and restarted CS agent on
problematic node.
Hope it helps
