HOWTO: FreeBSD ZFS add SSD as log/ZIL read cache to ROOT POOL

October 4, 2013

There is no way on a set bootfs pool to add log cache ,so we have to UNSET the bootfs first:

1. zpool bootfs= zroot   ( be carefull on the empty space bootfs= )

then add SSD as a cache

2. zpool add zroot log /dev/gpt/read-cache (or whatever your gpart add… name is)

then reset the bootfs on the zroot pool !!! ( Do not miss this please! )

3. zpool bootfs=zroot zroot

that;s all
