16.0E ExpandSize? -- New Server

[Steven Hartland]

Your issue is the reported vdev_max_asize > vdev_asize:
vdev_max_asize: 11947471798272
vdev_asize:     11947478089728

max asize is smaller than asize by 6291456

For raidz1 Xsize should be the smallest disk Xsize * disks so:
1991245299712 * 6 = 11947471798272

So your max asize looks right but asize looks too big

Expand Size is calculated by:
if (vd->vdev_aux == NULL && tvd != NULL && vd->vdev_max_asize != 0) {
     vs->vs_esize = P2ALIGN(vd->vdev_max_asize - vd->vdev_asize,
         1ULL << tvd->vdev_ms_shift);
}

So the question is why is asize too big?

Given you seem to have some random disk sizes do you have auto expand 
turned on?
