Please *don't* do that. While fsck (gfs_fsck), unmount the filesystem 
from *all* nodes.

Few things (for next time):
1. Any fsck should be run *without* being mounted. In GFS case, you 
should unmount the filesystem from all nodes.
2. All filesystem has their own fsck. So please be aware the difference.
3. For any tool you never use before, please at least browse thru the 
man page (in GFS case, "man gfs_fsck").
4. If you want to redo mkfs, *unmount* the current partition from all nodes.
