So I tried XFS last night and it cut my copy times down substantially, so I need someone to verify that XFS in centos 5.4 has barriers enabled by default, I am not using LVM just the old fashion partitions and mount points.  It appears that reading from the centos wiki that xfs is enabled in the kernel due to upstream vendor doing so for the first timeI loaded up xfsprogs and xfsdump but it was not clear about the barrier details....


Thanks...in advance. :)

 I've been using it since it first came out on SGI's under IRIX and have been
using it under Linux for a number of years.  It survives system crashes and
disk hardware problems and just keeps on going.  You will not find a better
file system out there.
