I upgraded a RELENG_13 box from last March to one today to bring in

was not there before. But the special devices (two 2TB samsungs) are
512 according to smartctl? Any idea why this warning popped up on the
pool all of a sudden? the disks and pool have been the same for a
year or so.
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 ?
