ZFS basics

•  Create a zpool named zonepool :

zpool create  zonespool c0t5000C5001D250C7Fd0   c0t5000C5001D207157d0

 zpool create -f oraclePool c0t5000C50007F554E3d0

• Create a FS namely zones in that pool

zfs create zonepool/zones

• Set a quota on files system

zfs set quota=10G zonepool/zones

Create a ZFS volume 

zfs create -V 20gb zonepool/zones

• Destroy zfs fs:

zfs destroy  zonepool/zones

• List the disks of all the zpools

zpool status

• List the file hierarchy

zfs list
root@T5-2-SDB-1:/# zfs list -r odsRoot
NAME                USED  AVAIL  REFER  MOUNTPOINT
odsRoot             103G  30.7G    31K  /odsRoot
odsRoot/zone1Root  51.6G  82.3G    16K  -
odsRoot/zone2Root  51.6G  82.3G    16K  -

• Destroy the zpool

zpool destroy zonespool

• Create Zvol from zpool :

 ZFS volume is a dataset that represents a block device. ZFS volumes are identified as devices in the /dev/zvol/{dsk,rdsk}/pool directory.
