[ovirt-users] how to prepare for an engine re-install

I'm running ovirt (engine 3.4.0-1.el6) on a dedicated engine machine with a
degraded raid array. This has caused the root filesystem to go read-only,
and the engine crashed. I can restart the engine, but after doing so, the
web page just loads a blank page. All nodes and VMs seem to be fine, I just
can't manage them via oVirt.
Because I'm offsite, my recovery option is likely limited to a reinstall of
the OS and ovirt. I'm hoping for some pointers on what I can do in advance
to minimize the pain of this transition.
- Am I going to be able to recover without having to shut down VMs,
exporting and importing?
- what directories should I back up?
- when I reinstall, should I upgrade and install 3.5.1, or first install
3.4, get it working, and then think about upgrading?
- Is it possible/recommended/crazy to migrate to a hosted engine instead
of a dedicated machine?
So I want to prepare for the worst before I try a reboot. If I'm lucky, the
reboot will at least come up with a writable filesystem, and I won't need to
re-install. If it doesn't come up, I want to be as ready as possible for
the reinstall.
Any hints and/or tips appreciated..
(I'll also be hanging out in the irc channel if anyone wants to respond in
that venue..)
