Known Problems and Workarounds
This section lists known problems, probable cause, and appropriate workarounds.
Serviceguard A.11.31.06:
Problem
If you run AutoFS on NFS servers that participate in a HA NFS cluster (through Serviceguard), the
behavior of building a local IP interface list may render Serviceguard unable to migrate an NFS
package during a fail-over event.
NOTE: This problem impacts only HA NFS server systems running AutoFS. You can safely use
AutoFS on client systems.
Cause
HA NFS uses relocatable IP addresses that migrate from a primary NFS server to an adoptive node
during a fail-over event. If you start AutoFS on an HA NFS server after Serviceguard is running,
these relocatable IP addresses are included in AutoFS' list of local IP interfaces. AutoFS map entries
referencing these relocatable addresses cause AutoFS to create LOFS mounts to the exported local
filesystems. These LOFS mounts may create problems with Serviceguard, because HA NFS does
not unmount LOFS filesystems before a package migration. AutoFS-managed LOFS mounts that
are holding resources in the exported filesystems, when Serviceguard tries to initiate a package
failover, may render Serviceguard unable to successfully unmount the local filesystems and migrate
them to the adoptive node.
Workaround
The workaround for this problem is to start automountd with the -L option. This can be done by
setting the AUTOMOUNTD_OPTIONS variable in the /etc/rc.config.d/nfsconf file before
automountd is started.
Software Availability in Native Languages
The Serviceguard NFS Toolkit is available only in the English language.
