I disconnected the lun from both nodes and it worked, the LV went to
linear. Thanks for the help!
One more question, what do you think about this testing scenario: Two-
nodes cluster, each node has a local disk which is exported via GNBD
to itself and to the other one. I build a cluster-mirrored LV on the
GNBD devices, then I kill one of the nodes. In this case, the cmirror
should work well? The LV will go to linear mode?

That's the problem. (C)LVM does not currently have a way to handle
the disappearance of a device from just one machine... it expects a
similar view of devices from all machines in a cluster. "Locking"
on the second node fails because it doesn't know what to do with the
disk that it sees (that has been removed from the node suffering the
failure).
There is someone working handling orphaned/removed devices that
reappear (which would be similar to this case), but I'm not sure if
they've taken this scenario into account. I'll let him know about
this.

Yes, I disconnected the lun via the Vtrak GUI from one of the nodes
(el4).

How are you performing the failures? It looks like just one
machine is loosing its connection to the device, while the other
machines links remain in place.
