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

[Jack Waterworth]

If you get anything back from this file-system I would be impressed.  
Losing 200GB of a file-system isnt something small that can just be 
"made up" to restore the data. The only options I can think of would be 
to (1) restore from backup, (2) copy as much data as you can off onto a 
new location, (3) fsck.    #1 is probably the best in your situation, 
however if that's not an option you should try to save as much data as 
possible (#2).

a fsck should be able to repair the file-system back into a "good" 
state, but you'll likely lose a lot of data. Can you show us the full 
error output you're getting when you try to fsck?

Also, keep in mind that this is an LVM mailing list... not a filesystem 
one. Perhaps you could get some help in #ext4 on the OFTC IRC.
