Hello,
Under FreeBSD 9, what filesystem should I use for PostgreSQL? (Dell
PowerEdge 2900, 24G mem, 10x2T SATA2 disk, Intel RAID controller.)
* ZFS is journaled, and it is more independent of the hardware. So if
the computer goes wrong, I can move the zfs array to a different server.
* UFS is not journaled. Also I have to rely on the RAID card to build
the RAID array. If there is a hw problem with it, then I won't be
able to recover the data easily.
I wonder if UFS has better performance or not. Or can you suggest
another fs? Just of the PGDATA directory.
Thanks,
Laszlo
