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.
