Testing : DRAID and TrueNAS CORE 13.0-U3

[JoeAtWork]

Hi All,

I have a system I want to test DRAID and run 13.0-U3, can I config the disks for DRAID in the GUI or is this a command line only process? Are there instructions on how to do this from the command line and are there system features that will not work on this test server?

Thanks,
Joe

On 13.0-U3, according to /usr/local/lib/python3.9/site-packages/middlewared/plugins/pool.py, line 506, the UI can only handle RAIDZ[1-3], MIRROR, and STRIPE data VDEVs. Thus, creating a pool with dRAID VDEVs is a CLI-only operation, using zpool create. See https://openzfs.github.io/openzfs-docs/Basic Concepts/dRAID Howto.html for more info.

Unless you have more than 8 disks, and data you're willing to sacrifice for testing, dRAID doesn't really have any benefits over standard RAIDZ.
