  Thanks for the reply Nathan - I am really confused here..

  I have a 137G production xfs filesystem, of which 79% of the blocks are used,
and 11% of the inodes are used.  The filesystem used 4K blocks.

  We seem to be on the verge of some hidden capacity limit as we keep getting
'no space left on device' even though there is 21% (30G) of free space.

  What could this possibly be? Its a RedHat 9 system with the kernel upgraded to
version 2.4.25, so its not cutting edge 2.4.. but its not all that old either..

  We are using xfs extended attributes heavily.

  Removing files and directories allows new ones to be created again but we cant
seem to get beyond the 79% mark. We are in a situation where we are continually
deleting files to prevent reaching the hidden capacity limit.

  Up until this point, there have been no problems with this filesystem.

  Any ideas?

No.

Unmount and run repair - does that show any disconnected inodes?
(if so, they'd be put in lost+found - these may account for your
missing space, if any exist..).

cheers.
