Enabling AutoFS on High Availability Servers Can
Cause NFS Packages to be Dropped
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.
How Do You Know
This Affects You?
You are affected if you enable AutoFS on an HA server.
What To Do 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.
