Hi, 

Which types of storage do you have in the data center?

In case it's a block based storage (iSCSI/FC), check that the devices (LUNs) where you domains reside are accessible though multipath and LVM:

# multipath -ll
# pvs
# vgs

In case it's a file based storage (NFS/GlusterFS), check that the storage domain file system is mounted under /rhev/data-center/mnt

# mount | grep  '/rhev/data-center'

Dear All,

Is there a reason that a perfectly well working Ovirt 4.1 Engine after a power failure, would not allow the hosts to activate because of  "VDSM  ConnectStorageServerVDS failed".  All firewalls are down, I have reinstalled the host, upgraded everything (host and engine), deleted and reinstalled hosts, I can ssh to all from all.  Any clues??

Thanks ahead of time..
