Hi guys,
As you may have guessed, from my posting, I'm having some LVM trouble.
Basically this is what has happened.
I got a new 200gig drive, and created an lvm1 pv/vg/lv. Copied loads of data
onto it, then put the drive into another machine.
After this worked I changed the metadata to lvm2.
Added another drive to the machine and extended the LV and extended the
filesystem, I then added another drive but created a new LV in the same VG,
then a third drive was added to a third LV.
And all was well, until...
Yesterday, even though everything was working, I was getting errors like:
Couldn't find device with uuid 'CrijJ6-qPj1-cSYX-HzQF-D4M8-TUkA-yK3FYc'.
Had to swap out the PSU this evening and then upon restarting couldn't
activate my VG :(
gandalf root # pvdisplay

"unknown device" is /dev/hde, my new 200gig drive, which IS working fine, and
IS exactly where is was before. So, after some googling, and practice on
another empty drive I decided to do:
gandalf root # pvcreate --uuid CrijJ6-qPj1-cSYX-HzQF-D4M8-TUkA-yK3FYc /dev/hde
No physical volume label read from /dev/hde
Physical volume "/dev/hde" successfully created
Which fixed pvdisplay, woo (not)

Aargggh!
Can someone suggest a course of action to get at my data, please?
I just need to iron out this kink in the road and my life long devotion to LVM
will be complete! :)
Cheers
p.s. gandalf is an Athlon 1.4GHz (at 1GHz), with a gig of ram, on board ATA133
and a Promise PCI ATA66, running 2.6.0-test6, and LVM 2.00.06. The 3 drives
IDE drives are on the PCI card (with an additional drive), 4 drives on the
on-board controller, and 2 SCSI disks is on an Adaptec AIC-7892A U160.
Attached is (hopefully) the full output of {pv,vg,lv}display and
{pv,vg,lv}scan.
