Be careful - adding one disk at a time to an aggregate is not a great idea if performance is of concern!!

Hi,

aggr add can work.

I was confused on the situation you met. I have 2 spare disks in the pool. But my aggr need more data space.

I run aggr add and got warning. I quit!!!

aggr add aggr1 -d 0a.26 0a.42                                                   

WARNING! Continuing with aggr add will result in a
low spares disk condition for one or more RAID groups.
Are you sure you want to continue with aggr add? n

I think it need spare disks in the pool. So how many spare disks it need? I have 2 Disk shelf, so I think maybe 2 spares.

At last, I tried add one disk, it succeed.

aggr add aggr1 -d 0a.26     

Addition of 1 disk to the aggregate has completed.

So I think it is better left one spare for pool.
