My typing is horrid so I simply ssh'd to a live CD env and pasted line = by line as per the how to found here; = http://wp.strahlert.net/wordpress/zfs-2/installing-freebsd-9-1-using-root-= on-zfs-and-gpt-disks/ All is well, no issues with replacing disks, testing failures etc... But seeing that my system drives are SSDs, I thought to perhaps add = noatime, etc... to avoid slow downs common in excessive SSD usage. However my fstab is only mounting swap partitions and I have no idea how = my file system is being mounted :) Also, I would like to use tunefs in finding if I have TRIM enabled as I = did load it via boot.conf I kinda feel like I'm willy nilly adding load lines w/o seeing if I = actually have the TRIM patch installed :) At any rate, could some one; a) Explain how I am loading my file system as I'm used to fstab? b) How to run tunefs on my zroot c) How to determine if I actually have the needed TRIM support in my = kernel I'm running 9.1 with the latest updates via freebsd-update = (fetch/install). Thanks in advance, -airf "I know enough to kill a system"
