Enabling AutoFS on High
Availability Servers Can Cause
NFS Packages to Be Dropped
You are affected if you enable AutoFS on an HA server.
Restarting NFS clients (with nfs.client stop/start)
or NFS servers (with nfs.server stop/start) while
NFS packages are running on the High Available (HA)
server will cause the exported file systems that tie to
NFS packages to be dropped.
This is because the SG-NFS exported file systems are
handled interactively and they are not in the
/etc/exports file. When stopping NFS clients or NFS
servers, it will unexport all the file systems on the
system through the /usr/sbin/exportfs -au
command. The file systems will be re-exported if they
have the entries in /etc/exports file at the starting
phase again, but not the file systems exported
interactively by the NFS packages.
Enabling AutoFS on the HA NFS server needs to be
done with caution. However, this kind of configuration
is fully supported if one of these two actions is taken
before stopping the AutoFS daemon:
1. Manually move all NFS packages to the adoptive
server node.
2. Halt all NFS packages.
The Auto FS daemon can be stopped either with the
kill -9 command, the nfs.client script, or the
nfs.server script.
Once the AutoFS daemon is restarted, the NFS
packages can be restarted or manually moved back to
the server node. AutoFS can be restarted either with
the /usr/sbin/automountd command or the
nfs.client script.
