Ok... So here is the deal. [correct me where I'm wrong, trying to speak simple here]
You got a zfs raidz1 pool of x disks. [Let's assume 5 disks of 1Tera each] The pool uses 1/x for parity. [That means 1/5 is reserved for parity] So you actual storage is x-1. [So that's [5-1] * 1Tera = 4Tera] And you remove one of the drives. The pool is still functional. All the data is there. Right? Right. You're left with x-1 disks but no parity. Right? Assuming your free space on the pool is more than 1/[x-1] [1/4 for our example] wouldn't it be very nice to ask zfs to recalculate it's parity and resilver all the drives to the new state? Is that posible? -- This message posted from opensolaris.org
