Also make sure the P600 is disabling the write caches on the drives themselves. Then... Mount with 'nobarrier' so XFS isn't interfering with the hardware cache performance of the P600. With barriers enabled (the default) XFS will periodically flush the cache on the RAID card causing write performance problems. -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
