While you are working on that, this is a good time to discuss triage. In all honesty, this is an old, unmaintained cluster. What is the hardware of the compute nodes?

The storage is poor. Even if we fix things, the system is very old in both software and hardware. So it's only a bandaid. Which is very doable, but it is what it is.

Doing a migration, like right now, might be the logical path forward. Let's get your specs for the current cluster, concerns for a new one and discuss if that's a real possibility. Also, what is the moment to moment impact of the outage?

I actually have a quote for a cluster from Scale that I had planned to try to push forward with the owner of the company when he returns from Europe next week. In the interest of properly giving you the information that you need, I want to be sure you're aware of that.

So the quote is already spec'd and ready to go? Maybe call him in Europe and see if things can be expedited? Would suck to have a major recovery operation happen just to hold off a discussion by one week.

tail -n 100 xen

tail -n 100 xen-dmesg

tail -n 100 xensource.log

[Dashrender]

Scott could make this a bit easier on you and give you specific paths in the commands

example

 tail -n 100 /var/log/xen
 tail -n 100 /var/log/xen-dmesg
 tail -n 100 /var/log/xensource.log

You can run these from path and they should give you the desired output

I'd need to talk to someone from Scale to understand the process and guarantees of it working, or the headaches involved before making that call. Can you tell me with whom you spoke, or have them contact my reps, Blake Dickmeyer and Frank Seal?

We know Frank well, he's on here as well. And he attended MangoCon this year (and he was at the Scale Legion event in Dallas a few weeks ago.)
