nech chces mat data v /local/data, tak nech:
1) pool nema mount point
# zfs set mountpoint=none mini #2) vytvorim si fs data:
# zfs create mini/data # zfs set mountpoint=/local/data mini/data # zfs list | grep mini mini 147K 27.4M 18K none mini/data 18K 27.4M 18K /local/data #skopiruj si vsetky data z ext3 sem ; ja len obrazne:
# touch yellow # ll total 4 drwxr-xr-x 2 root wheel 3 Nov 11 00:19 . drwxr-xr-x 6 root wheel 6 Nov 11 00:18 .. -rw-r--r-- 1 root wheel 0 Nov 11 00:19 yellow #a pridaj mirror:
