I have an external storage server and I created a zfs pool on it. # zpool list NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT export1 800G 277G 523G 34% 1.00x ONLINE - rpool 117G 109G 8.44G 92% 1.00x ONLINE - this pool is mounted under /export, all of the apache documents. are in this pool at /export/webserver/apache2/htdocs. The php temporary folder is set to /tmp, which is tmpfs.
