Hardlock and volume loss ?
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

Any ideas ? the software is:
Logical Volume Manager 0.9
Heinz Mauelshagen, Sistina Software 13/11/2000 (IOP 10)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

http://www-mddsp.enel.ucalgary.ca/People/adilger/ -- DogbertI 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
