You can use NFS to do something like this.  For example, if you have in
fstab(5):
{duid}.a /nfs/archive ffs rw,noatime,nodev,nosuid 1 3
localhost:/nfs/archive/dist/OpenBSD /var/www/ftp/pub/OpenBSD nfs
ro,nodev,nosuid 0 0

And you have in exports(5):
/nfs/archive/dist/OpenBSD -maproot=root -ro 127.0.0.1

Then you could have this arrangement showing via df(1)
/dev/sd2a                             28.9T   11.3T   16.1T    41%
 /nfs/archive
localhost:/nfs/archive/dist/OpenBSD   28.9T   11.3T   16.1T    41%
 /var/www/ftp/pub/OpenBSD

In this example I have the second mount read-only, but this is not required.
