Adding drives to RAIDZ1

[elangley]

Hello All,

I am running FreeNAS-9-2-1-3.

A volume (vol1) is configured with three 3TB drives in RAIDZ1 and 1 50 GB SSD as a log cache.

I would like to add another 3TB drive. In reading the documentation is says that 4 drives is RAIDZ2.

When I go to add the drive to the volume using the ZFS Volume Manager, selecting Volume to extend, the only options are "Stripe", Log, Cache and Spare, not RAIDZ2.

Is is possibly to add a drive to the existing RAIDZ1? And if so, how would I do that?

Thanks in advance,
~eric

no you can't add drives to vdevs. you can add more vdevs but to do that you are going to want 3 more drives to add. With zfs you shouldn't really be adding single drives like you want to do. Read this noob presentation and all your questions will be answered.
