Further...
Output from pvdata /dev/hde reveals that there is no vg info on the disk,
however there is vg info on the second disk /dev/hdb...
Is there any way of recovering the vg info from hdb onto hde ?

Subject: ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of
volume group "data_disks" from physical volume(s)
Dear List,
I have seen this problem in the archives, but cannot find a solution that
works for me.
Redhat 7.3 kernel 2.4.18-5
LVM module LVM version 1.0.1-rc4(ish)(03/10/2001)
I have two physical disks /dev/hde and /dev/hdb configured in LVM as Volume
Group data_disks.
I shutdown the system to add a new disk , but I did not execute
"vgchange -an" - my big mistake I think.
Having rebooted with the new disk I now have a problem trying to mount the
original vg.
The /proc/lvm/VGs directory is empty and /dev/data_disks is gone.
pvdisplay shows that the physical volumes are seemingly intact and still
have the correct configuration.
I have tried restoring the config from /etc/lvmconf/data_disks.conf to the
disks using vgcfgrestore - this makes no difference to my problem.
Basically, everything looks ok physically, but I need to figure out why
vgscan cant read the disks.
I have appended the output of vgscan,pvscan and pvdisplay below.
Thanks for any help anyone can offer...
