The upgrade from 3.5 to 3.6 was successful, as every subsequent minor
release upgrades. I rechecked the upgrade logs I haven't seen any
relevant error.
One addition information: I'm currently running on CentOS 7 and also the
original setup was on this release version.

Some moments before I saw the following lines into the vdsm.log of the
host that execute the hosted engine and that is the SPM, but I see the
same lines also on the other nodes:

After that I tried to execute a simple query on storage domains using
vdsClient and I got the following information:

# vdsClient -s 0 getStorageDomainsList
3b5db584-5d21-41dc-8f8d-712ce9423a27

# vdsClient -s 0 getStorageDomainInfo 3b5db584-5d21-41dc-8f8d-712ce9423a27
    uuid = 3b5db584-5d21-41dc-8f8d-712ce9423a27
    version = 3
    role = Regular
    remotePath = localhost:/hosted-engine

    type = NFS
    class = Data
    pool = []
    name = default
# vdsClient -s 0 getImagesList 3b5db584-5d21-41dc-8f8d-712ce9423a27
list index out of range

All other storage domains have the pool attribute defined, could be this
the issue? How can I assign to a pool the Hosted Engine Storage Domain?
