mmlsconfig command

Displays the current configuration data for a GPFS™ cluster.

Synopsis

mmlsconfig [Attribute[,Attribute...]] [-Y]

Availability

Available on all IBM Spectrum Scale™ editions.

Description

Use the mmlsconfig command to display the requested configuration attributes for a GPFS cluster. If no specific attributes are requested, the command displays all values that were set explicitly by the user. Depending on your configuration, additional information that is set by GPFS might be displayed. If a configuration attribute is not shown in the output of this command, the default value for that attribute, as documented in the mmchconfig command, is in effect.

Parameters

Attribute
Specifies the name of the attribute to be displayed. If an attribute has unique values that apply to only a subset of the nodes, the values are followed by the list of affected node names. You can specify more than one attribute in a comma-separated list.
Note: See the mmchconfig command for a list of supported attributes.
-Y
Displays the command output in a parseable format with a colon (:) as a field delimiter. Each column is described by a header.
Note: Fields that have a colon (:) are encoded to prevent confusion. For the set of characters that might be encoded, see the command documentation of mmclidecode. Use the mmclidecode command to decode the field.

Exit status

0
Successful completion.
nonzero
A failure occurred.

Security

The node on which the command is issued must be able to execute remote shell commands on any other node in the cluster. It must be able to do so without the use of a password and without producing any extraneous messages. For more information, see Requirements for administering a GPFS file system.

Examples

  1. To display the current configuration data for the GPFS cluster that you are running on, issue this command:
    mmlsconfig
    The system displays information similar to the following example:
    Configuration data for cluster small.cluster:
    ---------------------------------------------
    myNodeConfigNumber 1
    clusterName small.cluster
    clusterId 6339012640885012929
    autoload yes
    minReleaseLevel 4.2.0.0
    dmapiFileHandleSize 32
    [c6f1c3vp3]
    pagepool 512M
    [common]
    adminMode central
    
    File systems in cluster small.cluster:
    --------------------------------------
    /dev/fs1
    /dev/gpfs1
  2. To display the current values for the maxblocksize and pagepool attributes, issue the following command:
    mmlsconfig maxblocksize,pagepool
    The system displays information similar to the following example:
    maxblocksize 4M
    pagepool 1G
    pagepool 512M [c6f1c3vp3]
  3. To display the current value for the cipherList attribute, issue this command:
    mmlsconfig cipherList
    The system displays information similar to the following example:
    cipherList AUTHONLY
