Overview

ZFS is native to Oracle NAS Storage Appliance. With ZFS you can create a pool which you can share with out appliances through either NFS or Samba.

So let's create one pool:

Management

We can create a pool, using the zfs command line as follows:

[root@hostname ~]# zpool create tank -O casesensitivity=mixed -O compression=lz4 raidz2 disk1 disk2 disk3 disk4 disk5 disk6 disk7 disk8 disk9 disk10 -f

The following command, will create you a pool comprised by 10 disks in raid-5 configuration with double parity. The pool name is called: “tank”.

You can also list the status of the created pool as follows:

[root@hostname ~]# zpool list -v NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT tank 9.06T 1.94T 7.12T - 4% 21% 1.00x ONLINE - raidz2 9.06T 1.94T 7.12T - 4% 21% disk1 - - - - - - disk2 - - - - - - disk3 - - - - - - disk4 - - - - - - disk5 - - - - - - disk6 - - - - - - disk7 - - - - - - disk8 - - - - - - disk9 - - - - - - disk10 - - - - - -

If you are worried about the integrity of the pool, you can of course perform integrity check and verify the data corruption as follows:

[root@hostname ~]# zpool status -v tank pool: tank state: ONLINE scrub: scrub completed after 0h7m with 0 errors on Tue Tue Feb 2 12:54:00 2010 config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 raidz2: disk1 ONLINE 0 0 0 disk2 ONLINE 0 0 0 disk3 ONLINE 0 0 0 disk4 ONLINE 0 0 0 disk5 ONLINE 0 0 0 disk6 ONLINE 0 0 0 disk7 ONLINE 0 0 0 disk8 ONLINE 0 0 0 disk9 ONLINE 0 0 0 disk10 ONLINE 0 0 0 errors: No known data errors P.S. you can stop the scrubbing with: zpool scrub -s tank
