drives connected. All 7 show up in bios and in format. Here all the drives are

Hi,
First, I don't understand why parity takes so much space. From what
I know about parity, there is typically one parity bit per
byte. Therefore, the parity should be taking 1/8 of storage, not 1/3

Think of it as 1 bit
Hi,
I am going through understanding the fundamentals of raidz. From the man pages,
a raidz configuration of P disks and N parity provides (P-N)*X storage space
where X is the size of the disk. For example, if I have 3 disks of 10G each and
I configure it with raidz1, I will have 20G of usable

Yes, as long as the pools are on the same system, you can share
a spare between two pools, but we are not recommending sharing
spares at this time.
We'll keep you posted.
