'gfs_tool df' will probably help in accounting for all the space.

Your storage/powerpath has nothing to do with it.

reclaim turns FREEMETA blocks (free blocks that must be reused for
metadata) back into FREE blocks (free blocks that can be reused for
anything).  You shouldn't need to run 'gfs_tool reclaim' unless you have a
pathological use case.  reclaim isn't nice to use because it has to block
all fs access from all nodes while it runs.
