[tech] Mooneye upgrades

[David Adam]

With the power outages yesterday, [MSH] reminded us that one of Mooneye's 
disks has been throwing errors for a while. [TRS] and I decided to try and 
replace the drives with a pair of 36GB SATA Raptors scrounged from DAA 
(the company).

We only got about halfway through tonight, but Mooneye now has the drives 
and a Promise SX4 controller installed, and boots happily off the new 
disks. The controller does RAID, but we're using it in JBOD mode and 
relying on Linux's software RAID instead. Mooneye has been dragged kicking 
and screaming into the 21st century, using GRUB instead of LILO and 
leveraging LVM to give us more flexibility for future upgrades.

The filesystems haven't been synced over yet, but that shouldn't take too 
long tomorrow night. However, if we get time we'll probably also try and 
upgrade to a newer version of Debian, so there might be a few things that 
don't work straight away.

Sorry for the slightly-surprising loss in mail and DNS service. As always,
