Fellow Postgresql users,
I have a Pg 7.4.8 data on XFS RAID10 6-disc (U320 SCSI on LSI MegaRAID
w/bbu). The pg_xlog is on its own RAID1 with nothing else.
I don't have room for more drives, but I am considering moving the XFS
external log of the data directory to the RAID1 where the pg_xlog
exists. Unfortunately, I don't have room on the RAID1 that the OS exists
on(Centos Linux 4.1).
Anyone have any experience moving the XFS log to the pg_xlog? The
guessing the the benefit / cost will cancel each other out.
Thanks.
Steve Poe

There is absolutely no reason to move the xfs log on a system that
small.
