XFS developers - there were a few notes about not reading from a block
device with an XFS filesystem mounted (rw?).|
Will this interfere with lvm or device-mapper snapshots using the kernel vfs-lock patch? or xfs_freeze for that matter.
I'm wondering if the snapshot would see a consistent filesystem. My concern is with using EVMS, which is based on device-mapper snapshots.

We run postgresql on xfs (over LVM) on hardware raid (raid 50) with internal logs, and have done so for years now. Great performance, no data loss. In addition, xfs_freeze is very useful for doing backups: 1.) rsync from $PGDATA to a copy location
