Does https://www.freebsd.org/doc/handbook/disks-growing.html need updates because of cylinder checksums (ufs cotnext)?

[Mark Millard]

After following the procedure in:

https://www.freebsd.org/doc/handbook/disks-growing.html

to shrink a swap partition and grow a ufs file system
I'm now getting cylinder checksum failure notices.

Should the directions be updated in some way?

Or should growfs be updating something that is
is not now updating?
