Hello everyone,
My organization has an iSCSI LUN on a XenServer 6.0.2 host that is having
issues.
Last night we attempted a snapshot on a VM that is critical to our
infrastructure. During the snapshot, the task locked up and was unable to
progress or stop the snapshot. I attempted to force the VM to stop as well
as destroy it''s domain. As a last resort I had powercycled the host.
Upon bringing the host online again the LUNs failed to mount properly on
both of the hosts in the same cluster, entering a "Broken" state where
they
were listed as "unplugged" (two LUNs). This of course prevented the
VMs
from starting and we received a "VDI Not Found" error.
We ended up removing one of the hosts from the pool (the original master)
and forced the second server to become master. Once we did this we
attempted to remount the LUN and one of the two LUNs mounted properly. The
second LUN, which contained the most important pair of VMs of course, did
not mount properly. It is showing "Broken" / "Unplugged"
still.
At this point we are at a loss on how to get this LUN attached to the
system again and functioning. We know the data is there because of the
900GB available on the LUN, ~300GB is used (the size of the remaining VMs).
The data is intact, as far as we are aware, but we need to get it back and
functional.
Does anyone have any idea or can help? We tried calling Citrix support but
it won''t let us get past their "enter ping number" option to
speak to a
human, and we tried purchasing premium support on their website for our
license but it would not process any of the four credit cards we tried.
Is there another alternative for support available? Is there anyone that
has had the same issue successfully resolved?
