I have a backup drive that is formatted hfs+ (for my mac laptops) That I want to have available on my home network so I don't have to plug in directly. I have a pogoplug running arch linux (install is 3 days old with a 4gb flash drive as the disk), so I thought that if I could serve up the drive via nfs I could have wifi backup per this site: http://blog.mediafederation.com/andy-hawkins/mac-os-x-time-machine-via-nfs-on-linux-ubuntu-complete-guide-fixes-error-13-etc/
which would be swell, but when I try to export a folder (any folder I've tried) I get the error: "exportfs: /backup does not support NFS export". I read somewhere that nfs does not work on certain file systems, but I don't know anything more about that.
My nfs server seems to be running fine, on my other machine I get
rpcinfo -p 192.168.1.71 | grep nfs
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs
100003 4 tcp 2049 nfs
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 4 udp 2049 nfs
and no errors anywhere, I built hfsprogs and that is working--I can navigate and mount the hfs+ drive, but I cannot serve it up.
Why can I not serve it up? Any ideas? Should I try to make another partition that is a different file system and mount onto that and serve it up?
I'll be glad to answer any requests for more information about the setup. I am familiar with the bash shell, but if you want me to run an arch flavor command, you should probably type it out.

Since NFS uses an in-kernel server, the ability to export filesystems somewhat depends on that filesystem's driver. It could be that HFS just doesn't have this implemented yet. – user1686 – 2012-02-20T08:38:58.593
I cannot export the regular folders either. – JoshRagem – 2012-02-21T00:24:39.077
After doing a little more searching (prompted by your comment, @grawity) it seems that NFS cannot serve up HFS[+] unless it is compiled into the kernel. – JoshRagem – 2012-02-22T02:43:37.790
