You __can__ go through the hoops to do this. See the HOWTOs
(multi-disk, large disk, etc). However, I look on changing the / drive
as an opportunity to reinstall...
Buy two drives instead of one. Get Etch daily-build (unless its stable
by the time you get this:))
Install fresh setting up new drives with at least two raid1 partitions.
I have two 80 GB SATA drives, each with 3 partitions:
1 64 MB raid1 --> md0 --> mount on /boot
(since grub can't deal with LVM)
2 16 GB raid1 --> md1 --> LVM: VG-system
3 64 GB LVM: VG-local (therefore two devices in this VG)
lv-system-root 320 MB --> mount on /
lv-system-usr 4 GB --> mount on /usr
lv-system-var 4 GB --> mount on /var
lv-local-home 12 GB --> mount on /home
On-line backups of my stuff goes in /var/local/backup (untill copied to
other media) and is therefore protected by raid1.
This does two things:
Raid1 protects the installed system so that one drive failure doesn't
kill the system.
lv-local-home is just a straight LV. When I get into video editing, I
can create a stripped lv-local-video for better performance if needed.
Adding space later for /home is as simple as making it a PV and adding
it to the local VG.
If I __needed__ raid1 of /home, I would have forgon the vg-local and
just had two partitions on the drives.
Note that I have 1 GB swap so went with /tmp on tmpfs and put swap in
lv-system as an encrypted swap.
All this was set up in Etch's installer.
Runs great.
YMMV.
Doug.
