I have three drives, two of which make one data volume in Fedora 5.
The main drive still works fine but one of the two other drives
died. I get the following on the boot screen:

Setting up logical volume management: 2 logical volumes in colume
group "VolGroup00" now active 'fsck.ext3: Unable to resolve
'LABEL=/var'

The data on the two drives is not important. I was wondering if I
can replace the drive and have it become part of VolGroup00 without
reinstalling the OS.
At this point, it's usually stated that you can restore from your
most recent backup. :-)

Yep, and if you don't *have* a recent backup, this is the Universe
telling you why you should have one.

Perhaps it's time to consider building something newer. Perhaps with
Fedora 7 or so.
Fedora 7 becomes unsupported on June 13. F8 or F9 are your best
Fedora options.

The trouble with Fedora is that it has too many bugs, is too difficult
to upgrade, and goes out of date too quickly.

If you've got three drives, I'd suggest making RAID 1 (or 5) arrays
rather than volume groups. If you lose a drive in a volume group,
essentially the whole group is bad.

Fedora, for some bizarre reason, uses LVM2 by default. This can confuse
the hell out of newbies. LVM is a lot more flexible than partitions,
but it's also more complicated, and only Linux can read data stored on
LVM PVs. 3 drives = softRAID-5, which would give you the space of
2*(the smallest drive in the set). You can make a PV on that RAID
device, or not. Me, I have all my data on a 230G RAID-1 device that I
ran pvcreate on, but I've read all the HOWTOs and can troubleshoot well.
Tailor your setup to your level of experience, and you'll be better off
in the long run. HTH,
