Playing with ZFS 

Creating a ZFS pool & filesystem 

Identify disk to create the filesystem on, 

format 

^C 

Eventually wipe out the label and partitions, 

#dd if=/dev/zero of=/dev/rdsk/c2t1d0p0 bs=1024k count=1 

Create the ZFS pool, the ZFS filesystem and setup the mount point, 

zpool create local1 c2t1d0 

zfs create local1/foldername 

zfs list -r local1 

zfs set mountpoint=/opt/foldername local1/foldername 

check, 

zfs get mountpoint local1/foldername 

zfs get mounted local1/foldername 

zfs mount 

#zfs mount -a 

df -h
