-a, --empty

Output an empty CIB

-5, --md5-sum

-t, --timeout=value

Time (in seconds) to wait before declaring the operation failed

-U, --user=value

-n, --no-children

(Advanced) When querying an object, do not return include its children in the result

Data:

-X, --xml-text=value

Retrieve XML from the supplied string

-x, --xml-file=value

Retrieve XML from the named file

-p, --xml-pipe Retrieve XML from stdin

-o, --scope=value

Limit the scope of the operation to a specific section of the CIB.

Valid values are: nodes, resources, constraints, crm_config, rsc_defaults, op_defaults, status

-A, --xpath=value

A valid XPath to use instead of --scope,-o

-e, --node-path

When performing XPath queries, return the address of any matches found.

Eg: /cib/configuration/resources/master[@id='ms_RH1_SCS']/primitive[@id='prm_RH1_SCS']

-N, --node=value

(Advanced) Send command to the specified host

EXAMPLES

Query the configuration from the local node:

# cibadmin --query --local

Query just the cluster options configuration:

# cibadmin --query --scope crm_config

Query all 'target-role' settings:

# cibadmin --query --xpath "//nvpair[@name='target-role']"

Remove all 'is-managed' settings:

# cibadmin --delete-all --xpath "//nvpair[@name='is-managed']"

Remove the resource named 'old':

# cibadmin --delete --xml-text '<primitive id="old"/>'

Remove all resources from the configuration:

# cibadmin --replace --scope resources --xml-text '<resources/>'

Replace the complete configuration with the contents of $HOME/pacemaker.xml:

# cibadmin --replace --xml-file $HOME/pacemaker.xml

Replace the constraints section of the configuration with the contents of $HOME/constraints.xml:

# cibadmin --replace --scope constraints --xml-file $HOME/constraints.xml

Increase the configuration version to prevent old configurations from being loaded accidentally:

# cibadmin --modify --xml-text '<cib admin_epoch="admin_epoch++"/>'

Edit the configuration with your favorite $EDITOR:

# cibadmin --query > $HOME/local.xml

# $EDITOR $HOME/local.xml

# cibadmin --replace --xml-file $HOME/local.xml
