Serviceguard NFS Toolkit for Linux Version A.03.00 Release Notes, March 2009

This is due to exportfs -u, and the ESTALE is returned. When an interface is brought down,
the routes do not get flushed immediately. Therefore, the server keeps temporarily responding
after shutting down the interface.
What is the workaround?
Do the following steps on all the nodes, that are configured for running NFS package to set
min_delay to zero, while the system is running:
1. Run the command
# echo 0 > /proc/sys/net/ipv4/route/min_delay
2. Add the following line in /etc/sysctl.conf (in order to have persistent min_delay
value across server boots) net.ipv4.route.min_delay = 0.
NOTE: Instructions in steps 1 and 2 needs to be done all nodes.
Instruction in step 2 ensures that min_delay is set to zero after system reboot. This ensures that
persistent min_delay value is set across server reboots and hence after reboot, step 1 need not
be followed.
Can not create persistent minor numbers on RHEL4 U4
What is the problem?
lvm2 on RHEL4.4 had a bug so that the persistent configuration can not be created with
lvm2-2.02.06-6.0. For more information see the following web site:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=206091
What is the workaround?
There are two ways to address this issue:
1. Export the filesystem with an assigned filesystem identification.
2. Update to latest lvm2 package (lvm2-2.02.07).
