Expansion after openbsd nvme clone (growfs doesn't work)

hi all

Clone from 128GB nvme to 256GB nvme with dd and then clean up

with nvme , boot bsd.rd and the it doesn't work at fdisk -e sd1

In my case , I always create a swap partition first ,
then /tmp ,
and then create /,
so there is an empty part after /, so I can expand it.







1) boot PC wiith USB HDD (openbsd is installed)


２）256GB nvme is sd1

namely
# disklabel -E sd1

Label editor (enter '?' for help at any prompt)
sd1> p

3) fist 256GB nvme is rysnched to 320GB HDD (this is sd3)
# rsync -avHx /m1a/ /m3a/


4)now
# sysctl hw.disknames is

５）# umount /m1a



6)
# fdisk -e sd1
