zpool upgrade instructions aren't complete enough - gpart operation not permitted

[Paul Hargreaves]

Machine ‘a’

$ gpart show da0
=>      63  41942977  da0  MBR  (20G)
        63  41942943    1  freebsd  [active]  (20G)
  41943006        34       - free -  (17K)

So yes, that looks like MBR, so I’ll ignore the message on this machine.


Machine ‘b’   (joy of home labs)

Those two SSDs aren’t zroot and are part of an zpool so for those also should I ignore the GEOM errors?
I haven’t bothered upgrading this one yet but am about to.
