This hopefully gives me a three-way mirror:

          mirror     ONLINE       0     0     0
            c1t15d0  ONLINE       0     0     0
            c1t7d0   ONLINE       0     0     0
            c1t6d0   ONLINE       0     0     0

And then a

    zpool dettach tank c1t15d0

to get c1t15d0 out of the mirror to finally have

          mirror     ONLINE       0     0     0
            c1t6d0   ONLINE       0     0     0
            c1t7d0   ONLINE       0     0     0

again. Is that a good plan? I am then intending to do

       zpool add tank mirror c1t14d0 c1t15d0

to add another 146GB to the pool.

Please let me know if I am missing anything.

That looks OK and safe.

This is a production server. A failure of the pool would be fatal.

To whom??
