Is there any way to accomplish this?. Well, getting the data off is simple. Just dd from the surviving subdisk. There won't be much you can do with it, though, especially if the plex was striped. > Like replacing the broken hard drive with a new one and creating a new > plex on that or even removing the broken hard drive from the vinum > volume to only run the working hard drive? > I am asking this stuff before trying anything, because I would like to > know what chance I have before trying to change anything on the vinum > config and have it totally screw the data on the discs. Good idea. I've seen too many people throw away data because they assumed they couldn't get it back. You could try some of these methods; I'd certainly recommend backing up the accessible subdisk before trying anything. It's possible that you can use fsck with an alternate superblock to recover something, but if the first half is gone, the best you can hope for is a maze of twisty little lost+found files, all different.
