expanding Ture NAS storage

[m1nibuck]

so I'm currently trying to set up a True Nas NAS which i will admit now I'm very new to it all

I currently have 5 4TB hard drive which i was panning to run in a ZFS z2 which should give me 12TB of useable storage I think? but I was wondering in future can I add more drive to it as the case I'm using support up to 8 drives so in a years time can I add 3 more 4TB drive to have 24Tb of useable storage or dose it not work like that

thanks

No, ZFS can’t be expanded in this way.

 

In ZFS, you build vdevs out of drives, and vdevs can not be changed once they are created (except via replacing each drive one at a time with larger drives, rebuilding the array each time, eventually gaining the space of the larger drives once all drives are swapped out to the larger capacity), but you can add more vdevs to a pool. So you can add 3 more drives in their own vdev later, or you can replace all the drives (one at a time) with larger.

 

ZFS is extremely powerful and resilient, but it’s not architected to be cheap and affordable…

ok thanks 

dose unraid handle this defiantly

With UnRAID you can add drives at will, I have two UnRAID machines and I've easily expanded them one drive at a time.  The only catch is that any of your 'data drives' can be no larger than your 'parity drives'.  So if you build a whole UnRAID machine out of 8TB HDDs but want to add a 16TB HDD, you'll have to upgrade your 8TB parity drive to 16TB first. (But you could then recycle your former 8TB parity drive and use it as an 8TB data drive)
