LMV2 volume groups not found during boot

[Ian East <ian.east@gmail.com>]

I'm having a problem where my LVM volume groups are not found during
boot.   I have to manually scan and mount them after the OS boots.

Debian Sarge/2.6.11-1
Volume is on a 3ware 9500S-8

Here's a snipped from the boot sequence:

/dev/vg0/lv0:
The superblock could not be read or does not describe a correct ext2 
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the
superblock
is corrupt, and you might try running e2fsck with an alternate
superblock: 
    e2fsck -b 8193 <device>


fsck failed.  Please repair manually.

CONTROL-D will exit from this shell and continue system startup.

After I boot into the OS I have to manually vgscan and mount the
volume:

Any ideas on what's going wrong?

Thanks for any help.
