PV issues with LVM on 2.4.21

Hello -

I'm experiencing an error when trying to scan my volume groups after a
reboot. When running vgscan, I get:
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- ERROR "pv_read_all_pv_of_vg(): no PV" can't get data of volume group "storage" from physical volume(s) vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume group

I am running lvm 1.0.7 on top of software raid 5 on 2.4.21. I grabbed a fresh copy of 2.4.21 from kernel.org, configured lvm, made the patchset, patched the kernel, configed the kernel, and then made the kernel...so I think I'm following all the directions.

As the raid array is running without problems (all drives online, and array is clean), I suspect a problem with lvm.

Also, just for clarification, on a reboot (after I load the disk controller module, but before I run any lvm commands) if I dd /dev/zero over /dev/md/0, I am able to pvcreate, vgcreate, lvcreate, mkfs, and mount just fine. After a reboot, however, I get the above error.

Any ideas? I don't particularly like the idea of a 1/2TB of volatile storage.

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.
