Hmm.  Okay.  Though there are 6TB disks in the other array that are
quite old, I’m pretty sure could work in 512e mode, but diskinfo shows
a 4096 sectorsize for those too.   Oh well, I could be wrong about
how they work.

I can definately find another drive, likely even of the correct size.
But, that breaks my plan to increase the size of the pool by
replacing disks.  Am I correct that FreeBSD offers no way to
remove raidz vdev’s from a pool?  If it could I could try to construct
some sort of new pool a piece at a time.  But if it does not, then
there is nothing I can do I assume.  :-/

Happy to hear other thoughts.  I could move all of the data to
another system and rebuild it with a new vdev, but I’m not sure
if I care to grow the FS enough to do that.  :-)
