For the archive - I was able to solve this problem by naming my volume group something other than 'storage'. Although vgcreate would allow me to create the volume group named 'storage', I now suspect that one of my disks contained an incomplete signature for that volume group, and was confusing LVM. After zeroing out the beginning of the drives, I was able to create a volume group named 'storage' that lasts between reboots. - Nathan On Tue, Jul 08, 2003 at 04:05:24PM -0700, Nathan Hunsperger wrote: > Hello - > > I'm experiencing an error when trying to scan my volume groups after a > reboot.
