Message-ID: <20071029075657.GA84369978@melbourne.sgi.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Sender: xfs-bounce@oss.sgi.com Errors-to: xfs-bounce@oss.sgi.com List-Id: xfs To: xfs@oss.sgi.com Hello, XFS's default mount options are in most cases sub-optimal, we should try to have more sensible defaults, so far I'm following some quick dave-powered recomendations: - version 2 logs - attr2 - lazy superblock counters - less allocation groups for single disk configs - imaxpct default can be reduced it is currently 25, what would be reasonable ? - dropping the ability to turn unwritten extents off completely please submit your pet-idea for better defaults here.
