Depending on how often a system might sync()/fsync() this is true. As well as any FS options you use for mounting XFS volumes regarding log-buffers, io buffers, etc. > This is fixed in 1.3.1, > > Greg Yes, much better now.

This is more a function of hardware caching in a non-backed state, such as large cache buffers of some drives 8MB drive cache, etc. (i.e. no battery backed up cache) -- Austin Gonyou <austin@coremetrics.com> Coremetrics, Inc. _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
