The lv is available right?

It would be great to see the output from lvdisplay and vgdisplay.

I would think I should be able to find a backup superblock among the remaining drives. I tried running mke2fs -n to get a list of possible superblocks, but when I ran e2fsck with those values, I got the ioctl error, and then the no superblock found message.

Is there any way to scan each of the individual drives for data, outside of LVM? Just another desparate thought.

thx again.
