[Linux-cluster] 'df' not accurate?



Hi all,

  I have a cluster with 5 computers on board.  I have a GFS partition
that's about 1T.  When I run 'df', it shows that I've used 81G.  When
I run a 'du -s' on a subtree of the filesystem, I get ~250G.  I would
expect that the total in-use storage size would be about 300G.  The
quotas seem to add up to about 300G as well.  I manually created a 1M
file, and the usage went up by 1028 blocks.

  I'm using lock_dlm, RedHat 9, 2.6.9 kernel, all patches from CVS on
Nov 11.  Anyone else seen anything like this?  I don't have a few
days/weeks to fsck the system.
