[linux-lvm] Hardlock and volume loss ?

[linux-lvm] Hardlock and volume loss ?

[Kirth]

Hi,
	I've been playing with LVM for a few days, and finally decided to
risk 80gigs of data to it... bit of a mistake with hindsight. Earlier this
evening during an ftp transfer to the machine the box hardlocked. No errors
or anything, just completely dead to the world. On reboot I found i could
not access my LVM. After reading the postings, I had a poke and found that
while pvscan initally said it found the drives but didnt know which VG,
using vgcfgrestore i could fix that. The problem is if I try to make the PV
active, it "looses" this information and says 

milita:/etc/lvmconf# vgchange -ay
vgchange -- ERROR "Invalid argument" activating volume group "media"

	I've posted what I thought was relavent to
	http://black.hole.org/deadlvm.txt

	I'm pretty sure the data is intact, and I hope the lvm can be
put back together (hopefully so I can still resize/add to it)

	Any help would be apprecaited, oh and I'm running todays (12/13th
March 2001) cvs lvm programs.

Thanks in advance

Richard

In your other posting, you say:

> installed from lvm-0.9-2 via debian apt-get from sistina.com

Which one?  The 0.9 software has bugs that may cause this problem
(missing UUIDs).

Cheers, Andreas

I was using 0.9 originally when the machine hardlocked
I then upgraded to CVS after reading the mailing lists, this didnt help
I spoke to Hans who said go back to original 0.9 and try rebooting
and just running vgchange -a y (which fixed my problem, well at least
allows me to mount the drive, vgscan etc... still reset the UUID's)

I would like to fix the problem fully, so I can carry on using the LVM and
expand it, but at least right now I can copy the data off the drive.

Regards
Richard
