Okay, so I set up a basic NFS share to make sure that NFS was working. Some
things are showing more reasonable output. For example:
➜ ~ showmount -e localhost
Export list for localhost:
/srv/nfs-test 10.0.0.0/8
/srv/media 10.0.0.0/8
'/srv/nfs-test' is the plain NFS export for testing:
➜ ~ cat /etc/exports
/srv/nfs-test 10.0.0.0/8(rw)
I am now suddenly able to mount on the remote host both the test NFS export
and the ZFS NFS export.
Yay! Thanks for your help!
