I'm running on ZFS on a lightly loaded FreeBSD 7 box, and it's fine.
I did give ZFS the hint with recordsize=8K on the data directory/fs, but nothing else.
(other than the usual caveats with ZFS on FreeBSD (I'm on amd64)).

Subject: [ADMIN] PostgreSQL and ZFS
Hello all,
I am working with a PostgreSQL Database and I want to change the Filesystem to ZFS.
Does someone have experience with PostgreSQL and its Performance with ZFS? Are the current write options for PostgreSQL suitable for ZFS?
Do I need to finetune Postgres with the settings for ZFS?
- fsync
- wal_sync_method
Thanks if someone can help me on this.
