Hello everyone. I have a lot of 8TB drives that I want to use these in RAIDz. Never done this before I played with Stripe a few times; never nothing happened. But with these HGST drives I started thinking why not? And some lady luck on my side for once
I actually have eight thanks to my job where they bought these 8TB drives. The manager is getting all new 12TB drives (thanks to corporate) so the 8TB drives are no longer needed. They never got plugged in or nothing so still in packages when I got them. I have done Short and Long tests and they came out fine
So I thought, why not make a RAIDz with these so a couple of questions came to mind;
Q1 - I believe the minimum is 3 drives (2+1), is this correct?
Q2 - If I stay at 3 drives what will be the available space? 16TB (or a little less for the adjustment)?
Q3 - If I get more drives then will it be easy to just add to the pool?
Q4 - My understanding if there are more drives; not confirmed if used or not. If they are the 8TB variety and not used, I am wondering then if I make a RAIDz now with what I have, add my movies to the pool can I later (if there are more drives) go for RAIDz2 from RAIDz without losing data? If no then I can wait to find out what the other drives are.
Q5 - Maybe from Q4 I should ask another question. Only one to two systems access the pool for the shows at any given time. Would RAIDz then be just fine? Or better to use RAIDz2? I get the whole replace a drive when a drive goes bad, but I am also thinking about only 1-2 system access the shows so the server is really not be hammered by like 15 systems accessing it. I only use it for shows, no VM's, no jails just one big storage.
I also have another TN and it is the backup to all this so moving files around is not a problem. Just wondering now that I got a bunch of drives I can learn a new way; RAIDz or RAIDz2 (if I the more drives are the same)
Thanks
