Hi,
I'm no expert on this subject, but seeing as nobody else has replied
yet, I thought I would have a guess as to how this would work.

I want to upgrade, or re-install with CentOS and I don't want to have
to re-store all data on the RAID 5 volume but I am not sure that I
can because the LVM will use files from the system disk.
Will it? We used to use LVM on HPUX and although there was an
/etc/lvmtab file (think fstab), you could re-create it easily enough by
running the lvscan command. This same command exists on Linux (although
there is no lvmtab), and according to the man page it runs
automatically. There is also a --mknodes switch which is nice.
If you want to be sure that you can just slap a new OS on and it will
automatically scan for and set up your logical volumes, try booting from
a live Linux CD (Knoppix for example) and see if you can still see your
logical volumes.

Am I going to be able to maintain my existing LVM volumes during the
re-install? Is there a procedure to maintain LVM or store in after an
install or upgrade?
The system is backed but if I have to re-create the partitions and
restore it will be off-line for several days and I would need to
schedule it for a public holiday.
Any advice. Thanx,
Dp.
