Confused / Hosted-Engine won't start

2 Jul 2015

      I'm sure I have worked through this before, but I've been banging my head
against this one for a while now, and I think I'm too close to the issue.

Basically, my hosted-engine won't start anymore.  I do recall attempting to
migrate it to a new gluster-based NFS share recently, but I could have
sworn that was successful and working.  I _think_ I have some sort of id
issue with storage/volume/whatever id's, but I need some help digging
through it if someone would be so kind.

I have the following error in /var/log/libvirt/qemu/HostedEngine.log:

I also am including a few command outputs that I'm sure might help:

Can you anyone point me in the right direction here?  Eventually, I'd like
to get this hosted-engine running in HA mode (I had started this process
with ctdb/gluster/etc. via the well-known guide out there), but I'm
thinking that at this point, I should get this up and running again, export
everything, and perhaps just build a new hosted-engine and import things
into (if that is possible).  Right now, though, I just need to get this
hosted-engine run.

Many many thanks!
