Yes, the file system definitely needs to be offline and not mounted by 
any node.

BTW, I should also mention that the gfs2_convert tool won't convert file 
systems unless
they have the default (4K) block size.  If you created your file system 
with different block size,
then you can't convert it.  This was done purposely because of known 
GFS2 block size issues.
