ZFS
----------
      Create a pool with 3 mirror disks
          #zpool create -f local mirror c0t1d0 c1t9d0
          #zpool add local mirror c0t2d0 c1t10d0
          #zpool add local mirror c0t3d0 c1t11d0
          #zpool add local mirror c0t4d0 c1t12d0

      create a zfs file system
           #zfs create local/dwcons

      find out the zpool status
          #zpool status

      Destroy  zpool
          # zpool destroy  poolname

      Destroy zfs
          # zfs  destory name

      Display lis of zfs
          #zfs list  ;  zpool list

      Rename zfs file system
          #  zfs rename  tank/home/kustarz tank/home/kustarz_old

      Relocate zfs file system
          #  zfs rename tank/home/maybee  tank/ws/maybee

      Explicity set the mountpoint property
          #  zfs set mountpoint=/mnt  pool/filesystem

      Verify propery of the zfs
           # zfs get all pool/filesystem    or
                     to verify one properfy   ex:  zfs get mountpoint /pool/filesystem

      set mountpint legacy
           # zfs set mountpoint=legecy  tank/home/eschrock
           # mount -F zfs tank/home/eschrock /mnt
             add the file system entry in /etc/vfstab
             Ex: radg/oradata00       -                       /local/dwpoc/oradata00    zfs     -       no      -


       share zfs
            # zfs share tank/home/tabriz  (share tank/home/tabriz)
            # zfs  share -a                (share  all)

      unshare zfs		
            # zfs unshare -a		    (unshare all)	
            # zfs unshare tank/home/tabriz   (unshare tank/home/tabriz)

      set NFS share
            #  zfs set sharenfs=on tank/home
            #  zfs set sharenfs=ro tank/home

      set Reservation
            # zfs set reservation=4G tank/home

      set quota
           # zfs set quota=4G tank/home


       To import
              # zpool import
              #zpool import pool1

      To unmount a file system
              # zfs unmount pool1/testfs

     
      List physical volumes in a pool
              # zpool iostat -v  or zpool status -v pool1
