compute-1-1’s power supply died…

Friday, November 16th, 2012

They’re dying like flies… hahaha. Yeah. Ahem. I guess these ancient (2001) p/s’s can’t really be expected to last this long or handle what I’m throwing at them. They’ve done a bang-up job really, and hardly owe us anything…

Upgrade notes

Setting /etc/hostname to fly.local to fix the rpc.idmapd domain problem where users homedirs all mapped to being owned by nobody may not have been the right fix. Remember to set up backups again once things are up and running.

Problem list while upgrading cluster

Tuesday, November 13th, 2012

1. compute-1-2 has a bad power supply (that’s why it was down!
2. compute-1-5 has a bad exhaust fan
3. compute-4-5 (new monster node) will not post
4. compute-1-6 will not post

I guess I’ll try to figure out 4-5 first, since it’s most important…

Upgrading to ROCKS 6.0

Monday, November 12th, 2012

I will be rebuilding the cluster today, tomorrow, and Wednesday. I expect to take it down shortly and I don’t expect it to be fully functional again for a couple of days.
