I would say I don't trust osgeo4.

I believe it has a failed drive in it's raid, that we did not replace in
anticipation of moving to new hardware. Also because it already burned
through a couple of replacements, and the raid rebuild times were
agonizing.

osgeo6, is already in, and is the replacement machine for osgeo4, we
just haven't finished moving everything off. osgeo6 does not run ganeti
or kvm at this time. We have debated if it should.

I'm not sure we are using drbd for an instances anymore. Would it be
simpler to remove ganeti? Or is it possible to use other ganeti machines
you have as the 2nd disks for the shuffle and upgrade?

The new machine we are discussing is osgeo7 a replacement for osgeo3.

Lance, what's the rack and PDU situation? If there is room we can order
it sooner. Last I knew we needed to get osgeo4 off and out before we
could add anything else. If there is room we can order sooner.

Alternate option, what would be the cost if we just want to buy in to
existing Ganeti VM services OSUOSL is running? We aren't 100% sure the
direction we are going with containers, virtualization, and cloud
services. So an OSUOSL offer of "cloud" virtualization might be an option.

Thanks,
Alex
