[Triumf-linux-managers] updated rpcbind packages

[Kel Raywood]

This message is relevent for those that manage systems installed with 
el6 (CentOS-6 or Scientific Linux 6) and el7 (CentOS-7 or Scientific 
Linux 7).

New rpcbind packages are available that fix the bug that we first 
reported here by Konstantin Olchanski on May23 .
[ http://lists.triumf.ca/pipermail/triumf-linux-managers/2017/000360.html ]

As a reminder, rpcbind is used by NIS and NFS so is needed on most Linux 
PCs and many Linux servers at TRIUMF.

The packages have been available since mid last week for CentOS and 
Scientific Linux, and have been tested successfully on various TRIUMF 
systems.  So we now recommend that you update to the latest rpcbind 
packages.

==Update procedure for el6 and el7

If you locked rpcbind at it it's current version using "yum versionlock 
add rpcbind" then you will need to remove the lock. Unless you are 
specifically locking other packages (in which case you already know what 
you are doing) then the easiest way, is to just clean all locks.

     # Check what packages are locked
     yum versionlock list

    # Clear all locks
    yum versionlock clear

    # Re-add any locks that you still need

     # Update
     yum update

==What to do after updating rpcbind

This procedure is for el6.
On el7, replace "service <service-name> <command>"
            with "systemctl <command> <service-name>"

      # check that it is running
      service rpcbind status

      # On systems that do nfs-v3 mounting or serving
      service nfslock restart

      # On systems that do nfs-v3 serving
      service nfs restart

      # On NIS masters or slave servers
      service ypserv restart

      # After any update, it's good to check what needs restarting
      # to get updated shared-libs etc.  (this needs yum-utils installed)
      needs-restarting

      # check again that rpcbind is still running
      service rpcbind status
