You have used the new space for normal data or meta-data, so that it
isn't available anymore. "gfs_jadd" doesn't use the free space of a
file system, it needs to be fed up with new space, just like gfs_grow
As your file system cannot be shrinked, the only solution i see is to
add space one more time (much less, 150G is very much unless you want
to 100+ nodes), and run gfs_jadd again.

Cluster team, please correct me if i'm wrong.
