Hi
I would like to known if someone here have in production a FreeBSD server
with postgresql and the FS for the data of postgresql is a ZFS pool.
I'm going to buy some server with 96Go of Ram and a jbod of 12 disks (4To
each)
The purpose is to have everything on this zfs pool (except the system who
still on classic raid). So to have
many jail (~20-30) running apache/mysql/etc.
one postgresql server with all data on the zfs.
each jail use his own zfs partition. So I can use zfs send/received to have
a mirror of everything in a other server.
My question is about the performance, I known ZFS eat all memory he can
have (or almost), so what append when we run database like postgresql and
jail ? (it's also the reason of 96 Go ram).
Sorry for cross-posting but it's about 3 differents things....
Regards.
JAS
