[Cpqarray-discuss] Adding Disks to a logical Drive

[Bernhard G. <Ber...@un...>]

Maybe this has been discussed on this mailing list, but I can't access
the archive of this list (seems like the link is broken)

We're planing to use a ProLiant ML370 with an integrated Smart Array
Controller under RedHat 7.1.

I've done a test installation that is working fine.

I've got three 18 GB Disks and I've organized them into two logical
drives:
- one disk on its own
- two disks as a RAID-0

On the single disk I've installed / , /usr , swap and other partitions
that won't need more space in the forseeable future. The other logical
disk is a single partition (/home).
As my users are using lots of space this will have to grow.


My questions are:
- Is it possible to add another disk to the RAID and grow the /home
partition accordingly without losing the data on the /home partition
(according to the documentation this is only possible with WinNT and
OS2)?

- Same as above: Switching to RAID-5

- Similar question: adding a disk to the first virtual drive and
switching to RAID-1

Other questions are:

- Is ReiserFS better suited for the /home partition (right now I'm
using ext2, but the server isn't in use for the next week, so I could
easily change that) expecially with respect to partition resizing

- Is it better to organize all the phyical disks into one logical
drive and put /, /usr, /home etc on that huge drive


Sorry for that awful lot of questions. Any help would be most welcome.

Bernhard
