[linux-lvm] broken fs after removing disk from group

I got a lot back from this file system. I only lost what was on that 
dead disk and by chance there weren't much data on it, most is on the 
other 2. I already know what I lost, I was lucky and it's not very 
important: some GC heap dumps and some backup of phone sd card.

I made a backup of what was important now and so I'll be trying fsck. I 
hope it will work because I don't feel like rebuilding my lvm and copy 
everything again and lose what I consider not important.
