Sysmirror 7.1.3 Resource Group NFS mounts
Hello all,
I'm working to fix a two-node SysMirror cluster that uses NFS mounts from a NetApp appliance as the data repository. Currently all the NFS mounts/unmounts are called from the application controller scripts, and since file collection isn't currently working, (One fight at at time here..) the SAs need to remember to update the start/stop scripts on each node anytime changes are made.
My question is, is there a way to maintain and update the required NFS mounts for the resource group similar to how the filesystems and VGs are maintained by using the CSPOC commands to synchronize the changes across the cluster?
There's likely a cleaner way to implement this, but I haven't had enough practical interaction with HACMP/Sysmirror to really understand it.
Thanks!
Shawn

We have 2 servers in cluster. Node1 has an ext3 mount for backups and the other connects using NFS to this node1.

nfsmount.conf
NFSMOUNT.CONF(5) File Formats Manual NFSMOUNT.CONF(5)
NAME
nfsmount.conf - Configuration file for NFS mounts
SYNOPSIS
Configuration file for NFS mounts that allows options to be set globally, per server or per mount point.
DESCRIPTION
The configuration file is made up of multiple sections followed by variables associated with that section. A section is defined by a
string enclosed by [ and ] branches. Variables are assignment statements that assign values to particular variables using the = operator,
as in Proto=Tcp. Sections are broken up into three basic categories: Global options, Server options and Mount Point options.
[ NFSMount_Global_Options ] - This statically named section defines all of the global mount options that can be applied to every NFS mount.
[ Server "Server_Name" ] - This section defines all the mount options that should be used on mounts to a particular NFS server. The
"Server_Name" strings needs to be surrounded by '"' and be an exact match of the server name used in the mount command.
[ MountPoint "Mount_Point" ] - This section defines all the mount options that should be used on a particular mount point. The
"Mount_Point" string needs to be surrounded by '"' and be an exact match of the mount point used in the mount command.
EXAMPLES
These are some example lines of how sections and variables are defined in the configuration file.
[ NFSMount_Global_Options ]
Proto=Tcp
The TCP protocol will be used on every NFS mount.
[ Server "nfsserver.foo.com" ]
rsize=32k
wsize=32k
A 33k (32768 bytes) block size will be used as the read and write size on all mounts to the 'nfsserver.foo.com' server.
[ MountPoint "/export/home" ]
Background=True
All mounts to the '/export/home' export will be performed in the background (i.e. done asynchronously).
