Hello
OK, I read through https://forums.freenas.org/index.ph...ning-vdev-zpool-zil-and-l2arc-for-noobs.7775/
but still not clear...
I am on FreeNAS 9.3
I had a Single Hard Disk volume. (1TB disk)
I just purchased 2 5TB disks. My plan was to create it as a separate volume as Mirror. But while exploring, I was able to extend the existing volume (1TB) by adding the 2 new 5TB disks.
Now I have 1 Volume with 5.4 TB size.. So somehow, the 1 TB was mirrored (giving me 500GB usable).
So now, I have a 3 Disk Mirror... Coming from hardware RAID, I am not clear on how this is handled behind the scenes.
Does FreeNAS proportionally distribute data and mirror data across 3 drives now?
I am just trying to get my head around it... What happens if my volume is over 4 TB Filled and one of the 5TB disk fails?
In hardware RAID, this would not work, but in software RAID its allowing so I am just trying to make sure I understand whats happening under the cover..
Please explain (I am technical so no worries if you go techie)
