[linux-lvm] No pv after boot

[Shane Wegner]

Hi all,

I'm having trouble bringing up my LVM setup here after a
reboot.  I've tried 0.9.1b7, 1.0 and 1.0.1-rc1 patches and
tools match.  I believe my version is 2 but I am not sure
how to check that.  The kernel used it 2.2.19.

If anyone knows how I can correct this or at least recover
the data, I would be greatful.

Thanks in advance,
