Maybe gfs is on an odd device that gfs_tool can't match up with the
mountpoint.  Try this instead:

# gfs_tool list
18446675904036380672 sdb foo:x.0

# gfs_tool lockdump 18446675904036380672 > lockdump.txt

I can't really say what effect these non-default values would have.  Could
you try the default ilimits?

reclaim converts deallocated metadata blocks into normal free blocks.
Your problem is that inodes are never being deallocated in the first place
after being unlinked.
