Thanks for coming back to me about this, everyone else has gone quiet.
I updated my existing FC5 to rc11 and the mount problems went away! yay!
As I was saying, I'd setup a new install of FC5, but problems with the
Kernel made me consider a drastic move. I decided to copy my existing
setup across into the RAID container.
I cleaned out the target partitions first and the did a "find . -xdev |
cpio -pdam /<dest>" and copied everything into the new places.
I kept the Device.Map from Grub for the Original RAID install and copied
this back once I'd migrated.
I tweaked the /etc/fstab to ensure things pointed to the right labels.
It didn't work, I didn't get a device/mapper error, but then it couldn't
find the container and mount "root" (LABEL=/) and yes, I checked that
the RAID container volumes have an e2label that matches.
This last section of your response, kinda makes sense to me but it's a
bit beyond me. Can you please expand on the steps to:
1. "unpack the ramdisk" ? what file is this? how do I unpack this?
2. "edit that file manually"? what am I editing and what in particular
am I looking for?
3. repack? okay makes sense
If you can point me in the right direction of the unpack/pack and what
I'm editing this would be greatly appreciated.
I'm not to worred about getting rc13 yet. I think rc11 has fixed the
initial problems, and it sounds like your diagnosis about the mapping
being defunct is right! I just need to know how to fix it.
Thanks Heaps.
