ACK. Prefer raw devices. > ReiserFS on SuSE, ext3 on RedHat, both don't do each other much. > Just don't use XFS, it's quite slow compared to Reiser (out > of my experience), especially when writing. Hmm, when it's for performance, I'd never use a journaling file system for database files. It imposes a lot of logging overhead which is not neccessary because the database does its own logging. If the server crashes and the data volumes are damaged, then you have to restore anyway. So the journaling gives no benefit. > > - 3 Disks on Raid-5 for Data Besides for performance, RAID5 is not really the safety king as which it is sold.

ACK. The number of volumes should be equal to the number of physical disks.
