I had to restore back to a state previous to the creation of usrdata.  I
have LVM with system VG and so I captured it.  I get the same error when I
tried to add a logical volume to system also.

Ok, this looks like a difference between LVM and the LVM2 that comes with
2.6.  I guess "vgdisplay" and "ls -l /dev/usrdata" might tell us something.

I crossed up too many systems trying to get this to work and I had to
restore from backups.

I then ran "pvscan" sans quotes

>       techlnux:/proc # pvscan
>         PV /dev/dasdc1   VG system   lvm2 [2.29 GB / 0    free]
>         PV /dev/dasda1   VG system   lvm2 [2.29 GB / 68.00 MB free]
>         Total: 2 [4.58 GB] / in use: 2 [4.58 GB] / in no VG: 0 [0   ]

When I ran "cat /proc/lvm/global" sans quotes I received:

No such file or directory
