5.4 Configuring the Management Partition and Starting the File System Monitoring Mechanism

The following sections explain the initialization of the management partition, addition/deletion of node information, and start/stop of the management partition.

[Figure Setting up the management partition to start the file system monitoring mechanism]

1. Initializing the management partition

Use the sfcsetup(8) to initialize the management partition.

The initialization of the management partition is explained below.

For details on sfcsetup(8), see sfcsetup(8) in this manual.

To initialize the management partition, the file system monitoring mechanism must have already been stopped on the cluster system.

Specify a volume of the shared class created with GDS as the management partition. Note that a volume of at least 40 MB is necessary.

# sfcsetup -c /dev/sfdsk/gfs/rdsk/control

When a partition that is already initialized as the management partition is to be initialized again, execute the command with the -f option specified, as shown below:

# sfcsetup -c -f /dev/sfdsk/gfs/rdsk/control

2. Registering node information

When registering node information to the management partition, use sfcsetup(8).

An example of registering node information in the management information is explained below.

Register the node information on all the nodes on which the file system monitoring mechanism is to be executed.

• Registering a node in the management partition

# sfcsetup -a /dev/sfdsk/gfs/rdsk/control

• The path name of the management partition that has been set up can be confirmed by executing the sfcsetup(8) command with the -p option specified.

# sfcsetup -p
/dev/sfdsk/gfs/rdsk/control

• Registered node information can be confirmed by executing sfcsetup(8) with no option specified.

# sfcsetup
HOSTID      CIPNAME     MP_PATH
80000000    sunnyRMS    yes
80000001    moonyRMS    yes

3. Node deletion

Use the sfcsetup(8) command, when delete node information from the management partition.

The procedure for deleting node information from the management partition is explained below.

On the node that is to be deleted, the operation of the file system monitoring mechanism must have been stopped. Or, the operation of the file system monitoring mechanism for the entire cluster system must have been stopped.

On the node that is to be deleted, execute the command as shown below:

# sfcsetup -d

4. Starting the file system monitoring mechanism

Use the sfcfrmstart(8) command to start the file system monitoring mechanism.

For details on sfcfrmstart(8), see sfcfrmstart(8) in this manual.

To start the file system monitoring mechanism, node information must have been registered in the management partition.

Execute a command as follows on the node that wants to start operation of the file system monitoring mechanism.

# sfcfrmstart

5. Stopping the file system monitoring mechanism

Use sfcfrmstop(8) to stop the file system monitoring mechanism.

For details on sfcfrmstop(8), see sfcfrmstop(8) in this manual.

Execute the command on the node on which the file system monitoring mechanism is to be stopped, as shown below:

# sfcfrmstop
