I held off for a bit to see if someone else would jump in with a comparison of filesystems, but so far nobody has taken the bait. The reason I held off is that the only reasonable answer I can think of is, "It depends." Personally, I would stay away from any filesystem without journaling for allocations; which, for example, leaves out ext2. For various reasons I would also avoid ReiserFS. We've had good luck with xfs in our shop. There are some issues with recoverability of some file systems in some circumstances. There are often important configuration or mount option issues. What choices you make there will depend heavily on your usage. (A social networking site with data replicated to multiple servers may prefer speed over recoverability of any single server; most installations will not.) Your RAID configuration and controllers will likely make a bigger difference than your filesystem choices. Be sure to get good RAID controllers with battery-backed (BBU) cache, configured for write-back. If you post with more particulars, you will probably get more people jumping in with more specific advice. -Kevin -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
