Linux..

So one of the people here who used to do Systems Administration here was very old school. Install into 5 partitions (/ (1G), /usr (4G), /var (4G), /home, swap..) and make them all as small as humanly possible, and put the rest of the space into /local (65G), and put everything into there.

Which is all well and good, except things like, say, Redhat up2date, want plenty of space free. Today's fun:

- Break HW RAID mirror for backout plan
- Register system with Satellite server..
- Fail because it doesn't have the SSL certs for our Sat. server..
- Add certificates
- Register with RedHat Satellite
- Try running update
- Fail because of lack of HDD space
- Resize down /local
- Resize down LVM LV..
- Resize down LVM PV..
- Edit partition table to decrease PV partition size
- Create new partition (since existing partition with space in was in wrong VG..)
- Create PV in new partition
- Add PV to other VG
- Extend LV
- Expand filesystem, and find it fails due to old resize2fs
- Find ext2online, use that instead
- Right, now we have enough space, let's see what happens when we run up2date for the first time in ~3 years
- Amazingly, it works!

Yay Linux :P
