disklabel and df -h don't show same size

disklabel -h sd2 shows this

/mnt/extssd

but df -h shows this ..SSD is new and I followed
https://www.openbsd.org/faq/faq14.html encrypting external disks

Filesystem Size Used Avail Capacity Mounted on
/dev/sd3i 235G 4.0K 223G 1% /mnt/extssd

this is weird, does this have to be like this? or did I do something
wrong? I did do everything twice sxcept overwriting with /dev/urandom,
maybe it's that
also did bioctl -P -r newnumber after sd2 was decrypted and sd3 mounted
