what does `sysctl vfs.zfs.vdev.min_auto_ashift` say?
 sysctl vfs.zfs.vdev.min_auto_ashift
vfs.zfs.vdev.min_auto_ashift: 9

      

        
Sector Size:      512 bytes logical/physical


      

      
The SSD is doing read-copy-update behind the scenes to support a
512-byte sector size for compatibility reasons, the real sector size is
unlikely to be less than 4 kB and may actually be significantly larger.


    

    
Where what would be picking up the "true" size and why the change
      from a March 4th system to one today ?
