Installing and Configuring MC/ServiceGuard NFS

Configuring an MC/ServiceGuard NFS Package

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"

NOTE

The file name of the NFS_FLM_SCRIPT script must be limited to 14

 

characters or fewer.

 

 

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.

These arguments are passed using the NFS_SERVICE_CMD line in the hanfs.sh file.
