HowTo : Create RAIDZ2 ZPool

A RAIDZ2 Zpool is very similar in function to a RAID6 array. You get two parity points to prevent array failure in case of drive failures. A RAIDZ2 Zpool can tolerate two drive failures before it becomes vulnerable to data loss.

To create a RAIDZ2 Zpool first run the format command to find the disks that you have in your system.

Format Command

Once you have run the format command, you should have a list of disks that you can select for your Zpool. Select the ones that you would like to use (we’ll use c4t5d0-c4t8d0) and issue this command :

zpool create tank raidz2 c4t5d0 c4t6d0 c4t7d0 c4t8d0

Once you issue that command, it should build the zpool. Run the “zpool status” command to make sure it was created as expected.
