Yes, but we attempted that at one time with a smaller file system (for a different reason).   After letting it run for over a day, we estimated that it would have taken seven to ten days to finish.   That just wasn't practical for us at the time and still isn't.  This file system would probably take a couple of weeks to lfsck.  I'm sorry to say we can't take the file system offline for that long. 

We may just have to leave it as is until we put some new storage in place and can migrate the good data off it.   I just thought I'd ask. 

Thanks for the reply though,
