Hi everyone,
I'm a noob here and I'm trying to get started on FreeNAS.
Before I buy all the gear required, I have a question.
I understand that if I setup a vdev with three 2Tb drives in raidz1, I'll get ~4Tb of usable space.
Once a drive fails, I can replace it and (given that no other drive fails in the meantime) rebuild everything, not losing any data. Of course the replacement drive needs to be 2 Tb or greater, and here is my question: should I replace it with say a 4 Tb drive, can I make any use of the additional 2Tb data? Of course it would be totally not safe, since there's no redundancy, but it could be useful for less important stuff.
Same applies when the second 2Tb drive fails, can I replace it with a 4Tb drive and use the additional 2Tb? And when finally the last one of the 2Tb fails, I'd like to trash the two 2tb "partitions" and have the vdev expand to take advantage of the whole capacity of my drives, ~8Tb of usable space after parity.
Am I nuts? Is it doable even if partly?
Thank you all guys and greetings from Italy :)
