MC/ServiceGuard NFS Toolkit Version A.11.00.03 Release Notes

What’s in This Version

Details

The following 3 parameters for monitoring NFS services have been deﬁned in the nfs.mon ﬁle.

They carry default values. The user has the option to reset the defaults. The 3 arguments are

listed below in sequence:

1. INTERVAL: speciﬁes the interval in which ServiceGuard should re-check whether NFS

daemons are up and running. The default is set to 10 seconds.

2. LOCKD_RETRY: speciﬁes the number of attempts ServiceGuard make s to ping rpc.lockd

before giving up and exiting. The default is set to 4.

3. Third parameter speciﬁes the number of retry attempts ServiceGuard makes to ping NFS

services, namely, rpc.statd, rpc.mountd, rpc. nfsd and rpc. pcnfsd. The default value

speciﬁed, applies to all 4 NFS services. The user can specify only one value, which will

apply to all the 4 NFS services. The default is set to 4.

• STATD_RETRY - determines the number of attempts ServiceGuard makes to ping

rpc.statd before giving up and exiting.

• MOUNTD_RETRY- determines the number of attempts ServiceGuard makes to ping

rpc.mountd before giving up and exiting.

• NFSD_RETRY - determines the number of attempts Service Guard makes to ping

rpc.nfsd before giving up and exiting.

• PCNFSD_RETRY - determines the number of attempts ServiceGuard makes to ping

rpc.pcnfsd before giving up and exiting.

To reset new values, the user must go to “MC/ServiceGuard NFS TOOLKIT PACKAGE

CONTROL SCRIPT”. Here’s an example:

A user wants to reset the values for INTERVAL to 5 seconds, LOCKD_RETRY to 6 and the

NFS services- STATD_RETRY, MOUNTD_RETRY, NFSD_RETRY and PCNFSD_RETRY to

7. He can simply modify the NFS_SERVICE_CMD[0]="/etc/cmcluster/nfs/nfs.mon" variable in

the Control Script to,

NFS_SERVICE_CMD[0]="/etc/cmcluster/nfs/nfs.mon 5 6 7".

5 will apply to INTERVAL, 6 to LOCKD_RETRY and 7 to STATD_RETRY,

MOUNTD_RETRY, NFSD_RETRY and PCNFSD_RETRY.

For the new values to take immediate effect, the user must re-run the NFS package.

NOTE To run MC/Service GuardNFS over TCP, the user needs to verify whether NFS/

TCP services are enabled on his system.
