Hi All,
We're migrating to new hardware and to pgsql 8.3.1 from pgsql
<http://8.2.4.>8.2.4. We were scheduled to go live yesterday
morning but elected not to late Friday after observing this issue:
Our new hardware includes an external Dell MD3000 RAID array of 15
15k SAS disks. We have a 2 disk RAID1 array for txnlog and a 12
disk RAID10 array for pgsql data.
Try the bonnie++ benchmark on the RAID1 txn log array.
Maybe you should try a 4 disk RAID10 array for txn log (or even more
disks :) ).
