Known Problems and Workarounds
The following lists known problems, probable cause, and appropriate workarounds
for Serviceguard A.11.31.02:
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.
