Sorry for not providing more context. ATHENA:/var/pgsql/data # uname -a Linux ATHENA 2.6.16.60-0.39.3-smp #1 SMP Mon May 11 11:46:34 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux ATHENA:/var/pgsql/data # cat /etc/SuSE-release SUSE Linux Enterprise Server 10 (x86_64) VERSION = 10 PATCHLEVEL = 2 File system is xfs noatime,nobarrier for all data; OS is on ext3. I *think* the pg_xlog mirrored pair is hanging off the same BBU-writeback controller as the big RAID, but I'd have to track down the hardware tech to confirm, and he's out today. System has 16 Xeon CPUs and 64 GB RAM. -Kevin
