Autofs supports a list of NFS servers to be checked, in order, for NFS shares. I've found it very useful in migration situations. We could spend a lot of time going over approaches for that. I've also found it really useful to make "/homedir/{usernames}" a pool of symlinks to an NFS automount layout. That way, I can switch users from one NFS automoun to another by updating the symlinks in a deployed network. Very handy for switching and re-arranging upstream NFS or attached storage in a planned fashion. It ain't perfect, but lord, it's useful. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
