comment Missing LV in VG in LVM partition on Ubuntu
thanks for checking back... no I haven't got the data back yet :-( One thing I forgot to mention is that this HDD used to be part of a RAID1 array. One drive physically died and the other one is messed up (as described above). I'm not sure if that changes things when it comes to data recovery or not. I'm ready to supply whatever other information is necessary but I'm not sure what else would help people to solve this problem!

Also, the entire OS was installed on the LV that is missing so I don't have access to edit the fstab nor is there any hope of booting. I've just mounted the drive in another computer for analysis.

thanks for your answer. pvscan -vvv spits out an awful lot but there is nothing in there ignored by filtering. What I did notice, though, is that when it reads the metadata from /dev/sdb3, it lists /dev/sdb3 0, /dev/sdb3 1 and /dev/sdb3 2. It's more information than I got from running lvs which didn't show the 3rd one as 1191 475679: NULL(0:0). I've never seen this before. The other 2 are root(0:0) and swap_1(0:0).

@Bittrance - I've added the output of vgdisplay to the question because the formatting works better than in a comment.

@JiriXichtkniha - 'vgscan --mknodes' gives the same result as I pasted for 'vgscan' above. /etc is inside the lost volume so I can't view it.

comment Huge amounts of “multiply-claimed blocks” during fsck
I'm using ext4 exactly as the default installation of Ubuntu Server 10.04 selected. Thanks for confirming that the zero files thing makes no sense. But is it possible that the error could just be caused by faulty hardware rather than a software bug?

To answer your questions, it's a VM server running KVM. The filesystem is 2TB but is mostly empty. There's just the OS and the 100GB VM image.
