​Right, I had forgotten that its in a failed drive state.​

​You can't mixed Ganeti clusters ​unfortunately so we'd have to add a
completely new node.

​We have plenty of room now​ so feel free to get that started.

Alternate option, what would be the cost if we just want to buy in to

​​Our primary VM infrastructure is still based on Ganeti, however we've
been exploring using OpenStack as an alternative for more elastic needs.
We've been running an OpenStack cluster for the past several years on the
ppc64le platform, but we haven't created a cluster for x86 yet. I was
hoping we'd get something like that deployed sometime next year, but it
depends on various factors.

What exactly are your needs in the medium and long term? We could put you
on our primary Ganeti cluster but we have to be careful with any I/O
intensive VMs so they don't impact other users.
