Hello,
I have a server with a total of 4 drives:
# dmesg | grep ad | grep device
ada0: <INTEL SSDSA2CT040G3 4PC10362> ATA-8 SATA 2.x device
ada1: <INTEL SSDSA2CT040G3 4PC10362> ATA-8 SATA 2.x device
ada2: <ST2000DM001-9YN164 CC4C> ATA-8 SATA 3.x device
ada3: <ST2000DM001-9YN164 CC4C> ATA-8 SATA 3.x device
ada0 and ada1 are 40Gb each
with ada2 and ada3 being 2Tb each
here are the full details:
http://pastie.org/3904764
i have followed several tutorials of setting up ZFS but have a question:
is it a good idea to have /var reside on the 2Tb drive and /usr on the 40Gb?
here is how i set it up http://pastie.org/3925356, and on line 63
zfs create -o compression=gzip -o exec=off -o setuid=off pool0/ROOT/usr/src
zfs create -o compression=gzip -o setuid=off pool0/ROOT/usr/ports
zfs create -o compression=off -o exec=off -o setuid=off

zfs create -o compression=off -o exec=off -o setuid=off
pool0/ROOT/usr/ports/packages
zfs create -o compression=lzjb pool0/ROOT/usr/obj
zfs create -o compression=on -o exec=on -o setuid=off pool1/ROOT/tmp
zfs create -o compression=lzjb -o exec=off -o setuid=off
pool1/ROOT/var/crash
zfs create -o compression=off -o exec=off -o setuid=off pool1/ROOT/var/empty
zfs create -o compression=lzjb -o exec=on -o setuid=off pool1/ROOT/var/tmp
any advise of making this better much appreciated.
