Description Alexandre Oliva 2001-06-08 01:56:33 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.2-2 i686; en-US; rv:0.9)

Description of problem:
I have a machine with a few RAID filesystems that I'd like to preserve
across a new full install (not upgrade).
Currently, what I have to do is to leave the RAID partitions unused, and
set them up in /etc/raidtab and /etc/fstab after the installation is completed.
What I'd like to be able to do is to tell disk druid to load a pre-existing
raidtab from somewhere (say /boot/raidtab, where I keep a copy of
/etc/raidtab), so that I'd be able to tell the installer where to mount
these partitions (extra bonus for loading /etc/fstab from somewhere too :-)
and get the box ready to go at the first boot.

How reproducible:

Steps to Reproduce:
1.Install the system and create a couple of RAID/ext2 filesystems.
2.Decide to re-install it, willing to preserve the existing RAID filesystems.
3.Have to introduce the raid devices only after the full installation,
because disk druid says creating the raid devices will clobber the existing
data in those partitions.

Actual Results:  The system won't have the RAID filesystems on the first
boot, and they have to be configured in /etc/fstab and /etc/raidtab manually.

Expected Results:  Have the installer read raidtab from the previous
installation or from some other place so as to preserve the information
across the re-install.

Additional info:

It may be that I could create the raid devices, and just tell the installer
to preserve those filesystems, but I didn't have the guts to try it.

This is an interesting idea.  Assigning to msw as it is related to his work on
