We recently added a bunch of Western Digital 3.0TB Green drives to the enclosure, so that we can run a bunch of tests with this brand. Here’s a quick recap what I had to do to make these new disks online.
First run the diskmap.py. the bold lines are my commands which I wrote. First I discover for new drives (it might that the diskmap shows an old cache without the new drivers) and then I ask it to lisk all disks.

I colored the new disk ids with yellow for your reading pleasure. Next I copied all those 11 ids and I formed the following command, which creates a new tank. I also reused the three old spares, those disk ids are marked with green.
zpool create tank2 raidz3 c2t50014EE2B1158E58d0 ... c2t5000C5003EE49672d0 spares c2t5000C5003EF2D1D0d0 c2t5000C5003EEEBC8Cd0 c2t5000C5003EE49672d0
All set! I could now access the new 30TB volume under /tank2.
Shouldn’t it be zpool create tank2 raidz3 for the zpool create command?
Thank you for this useful info, as well as the original article on building the storage server.
Have you had any trouble with the system so far?

Good catch, you’re correct.
We haven’t had so far any problems with the system. And nice to hear that this was helpful :)
