Editing the NFS Monitor Script (nfs.mon)

The NFS monitor script, nfs.mon, contains NFS-specific monitor variables and functions. The nfs.mon script is an optional component of HA/NFS. The hanfs.sh file specifies whether the NFS monitor script is used. The following steps describe how to configure the NFS monitor script:

1.To monitor the File Lock Migration script (nfs.flm), set the

NFS_FILE_LOCK_MIGRATION variable to 1, and set the

NFS_FLM_SCRIPT name to match the hanfs.sh script value for this variable:

NFS_FILE_LOCK_MIGRATION=1

NFS_FLM_SCRIPT="${0%/*}nfs1.flm"

The file name of the NFS_FLM_SCRIPT script must be limited to 13 characters or fewer.

The nfs.mon script uses rpcinfo calls to check the status of various processes. If the rpcbind process is not running, the rpcinfo calls time out after 75 seconds. Because 10 rpcinfo calls are attempted before failover, it takes approximately 12 minutes to detect the failure. This problem has been fixed in release version 11.11.04 and 11.23.03.

2.You can call the nfs.mon script with the following optional arguments:

•Interval - the time (in seconds) between the attempts for checking if NFS processes are up and running. The default is 10 seconds.

•Lockd Retry - the number of attempts to ping rpc.lockd before exiting. The default is 4 attempts.

•Retry - the number of attempts to ping the rpc.statd, rpc.mountd, nfsd, rpc.pcnfsd, and nfs.flm processes before exiting. The default is 4 attempts.

•Portmap Retry - the number of attempts to ping the rpcbind process before exiting. The default is 4 attempts.
