I'm using NFSv4 but suddenly when the NFS Server got rebooted, all the files on the Clients are having nobody ownerships after the Server is booted and started its whatever services again.



Then I found some solutions to set the Domain=_____ in the idmapd.conf file.



  • But what am I suppose to put there (in both Server and Clients)?

  • I only have IP addresses.

If you actually have a valid, globally-unique domain name reserved to you, that is of course a great choice.



But more important than the actual value of the NFS4 domain setting is probably that the same domain setting is used both in the NFS4 server and all its clients. If the domains are different, the server will treat all client users as nobody.

    According to Wikipedia.
    this would be <hostname>.<domainname> or simply your hostname if you are not part of a domain.



    Fancy "stolen" one-liner:



    echo `uname -n`.`awk '/^domain/ print $2' /etc/resolv.conf`


    If the result ends in <hostname>., delete the . => you are not part of a domain.
