So, as I go along with my tasks, I need to export part of a client's afs
tree via NFS to support live streaming of content on that cached copy
before it is closed and flushed to the volume.
So, I followed the AFS/NFS instructions.
I added -rmtsys to OPTIONS in afs.conf, and it shows up in the ps of the
afsd process now. I even verified that the kernel module gets unloaded
between restarts.
root 6119 2 6119 0 1 15:56 ? 00:00:00 [afsd]
root 6131 1 6131 0 1 15:56 pts/1 00:00:00 /sbin/afsd
-rmtsys -dynroot -fakestat
I setup the NFS server and exported one volume other than afs to test it
via nfsv3. Worked just fine.
unfortunately, when I try to export the /afs volume, I get this:
exportfs: /afs does not support NFS export
and when I do the explicit fs exportafs nfs command, I get this:
Sorry, the nfs-exporter type is currently not supported on this AFS client
Below is the strace of the fs command. Its very short. I'll say in advance,
the file /proc/fs/openafs/afs_ioctl is there.
Does anyone have some advice? I'm still working the problem, but the docs
are definitely weak on this one.
