GFS2: fsck.gfs2 reported statfs error after gfs2_grow
From: Bob Peterson <firstname.lastname@example.org>
When you do gfs2_grow it failed to take the very last
rgrp into account when adding up the new free space due
to an off-by-one error. It was not reading the last
rgrp from the rindex because of a check for "<=" that
should have been "<". Therefore, fsck.gfs2 was finding
(and fixing) an error with the system statfs file.
