[Didn't get any replies on the Perform list -- hoping someone can help me here] Hi. We have a server provided for a test of a web application with the following specifications: 1 Dual core 1.8GHz Opteron chip 6 GB RAM approx 250GB of RAID10 storage (LSI card + BBU, 4 x 15000 RPM,16MB Cache SCSI disks) The database itself is very unlikely to use up more than 50GB of storage -- however we are going to be storing pictures and movies etc etc on the server. I understand that it is better to run pg_xlog on a separate spindle but we don't have that option available at present. Normally I use ext3. I wondered if I should make my normal partitions and then make a +/- 200GB LVM VG and then slice that initially into a 100GB ext3 data directory and a 50GB xfs postgres data area, giving 100GB to use between these as they grow. I haven't used LVM with xfs before, however. Advice gratefully received. Rory
