How to Warm-Start rpcbind

If the NFS server can not be rebooted because of work in progress, it is possible to restart rpcbind without having to restart all of the services that use RPC by completing a warm start as described in this procedure.

  1. As root on the server, get the PID for rpcbind.

    Run ps to get the PID (which is the value in the second column).


    # ps -ef |grep rpcbind
    root   115     1  0   May 31 ?        0:14 /usr/sbin/rpcbind
    root 13000  6944  0 11:11:15 pts/3    0:00 grep rpcbind

  2. Send a SIGTERM signal to the rpcbind process.

    In this example, term is the signal that is to be sent and 115 is the PID for the program (see the kill(1) man page). This causes rpcbind to create a list of the current registered services in /tmp/portmap.file and /tmp/rpcbind.file.


    # kill -s term 115
    Note -

    If you do not kill the rpcbind process with the -s term option, then you cannot complete a warm start of rpcbind and will have to reboot the server to restore service.

  3. Restart rpcbind.

    Do a warm restart of the command so that the files created by the kill command are consulted, and the process resumes without requiring that all of the RPC services be restarted (see the rpcbind(1M) man page).


    # /usr/sbin/rpcbind -w
