[ovirt-users] Storage domain issue

Greetings.

Running oVirt 3.5 with a mix of NFS and FC Storage.

Engine running on a seperate KVM VM and Node installed with a pre 3.5 
ovirt-node "ovirt-node-iso-3.5.0.ovirt35.20140912.el6 (Edited)"

I had some problems with my FC-Storage where the LUNS for a while became 
unavailable to my Ovirt-host. Everything is now up and running and those 
luns again are accessible by the host. The NFS domains goes back online 
but the FC does not.

Running the command above manually does indeed give the same output:

# /sbin/lvm vgs --config ' devices { preferred_names = ["^/dev/mapper/"] 
ignore_suspended_devices=1 write_cache_state=0 
disable_after_error_count=3 obtain_device_list_from_udev=0 filter = [

retain_days = 0 } ' --noheadings --units b --nosuffix --separator '|'

   Skipping volume group 29f9b165-3674-4384-a1d4-7aa87d923d56

What puzzles me is that those volume does exist.

Could someone (pretty please with sugar on top) point me in the right 
direction ?
