No.
Adding, removing, or otherwise changing disks in a RAIDZ is not possible

Ian,
You might consider converting this pool to a mirrored pool, which is
currently more flexible than a raidz pool and provide good performance.
Its easy too. See the example below.

Hi David,
In general, an I/O error means that the slice 0 doesn't exist

Hi David,
Make sure you test booting from the newly attached disk and update the

this? Otherwise I will just use dd. Thanks again!
Thanks!
