I have acquired a rather large UPS. Used of course, but wasn’t of much use to its previous owner. I also have come across a quad-Xeon workstation, with 16GB of RAM, which I think would make a splendid server for the blog. I’ve had the Xeon for a while, actually, but what’s kept me using the older box is that it’s pretty miserly with electricity, giving it a nice run time on UPS power. Well, now I have a big honkin’ UPS, so that’s less of a concern.
But the quad-Xeon is much faster, and has twice the RAM. The only issue is, I’m using dmraid (FakeRaid) in the current box to do mirroring, because I was short sighted, and didn’t think through the consequences. Ordinarily, I’d just move the mirrored pair over, and things should be fine. But I have to break the dmraid pair, and convert to to Linux software RAID. This is doable, but a bit of a PITA. So I need to do this after hours. I think I can make the transition without incurring any serious downtime.
My plan so far is to remove one drive from the current mirror, and let it run degraded. Set up a degraded software mirror on the new system with the drive I took out, and then copy data from the current box over, while live. Once the new box is running as a copy, albeit an outdated one, briefly shut down the current box and update the files that have changed. After that I should be able to come up on the new server, add the other drive, rebuild the mirrored pair, and we’re good to go.
