I added scsi hard disk (total 2) and move some folders on my fc3 machine. And erased some folder.
After "yum -y update",


[root@www var]# lvscan
Couldn't find device with uuid 'ZEvOKn-iabd-NXt6-svoz-6f0L-uA25-t61qEB'.
Couldn't find all physical volumes for volume group VolGroup00.
Volume group "VolGroup00" not found

And lvm backup is::

}

extent_count = 32 # 1024 Megabytes

type = "striped"
stripe_count = 1 # linear

stripes = [
"pv0", 1048
]
}
}
}
}

But, I didn't reboot, and can see the folders on new hard disk.

pvcreate -u ZEvOKn-iabd-NXt6-svoz-6f0L-uA25-t61qEB /dev/sdb1

Will this work and restore uuid for sdb1?

I have a somewhat similar situation, I removed a windows partition which was my second hard drive and since I wasn't comfortable with my knowledge with linux I did a reinstall but it seems when disk druid partitioned the hard drives it didn't clear the mbr so now I get this:
[root@spike sbin]# ./lvscan
ACTIVE '/dev/VolGroup02/LogVol00' [222.41 GB] inherit
ACTIVE '/dev/VolGroup02/LogVol01' [1.00 GB] inherit
Couldn't find device with uuid 'S6HTah-oYA8-NzeD-4Ehg-Ct5A-v1gO-S0DM9B'.
Couldn't find all physical volumes for volume group VolGroup00.

How do I get rid of the old volume groups etc?
