Work on home server greenblatt: time for less disks with more storage.
So I bought two sata disks, one huge one to store the camera archive and
scratch files, and one for the system and home directories. The choice for
two disks is so the one with the camera archive and the scratch files can
fall asleep when not in use, to save a bit of power. Installing both new
disks at once wasn't going to happen due to space and cabling considerations
so I started with the big one. When that one is done I can remove three
pata disks from the system. I also updated the system bios to the latest
version which made the system clock a lot more stable, ntpd now runs
without having to use tickadj. Bios updates are easy these days: this bios
can update itself from a USB stick. I chose logical volume management (lvm2)
again for managing the big disks so it will be easy to expand storage when
needed without getting a big tree of filesystem mounts.
