Will fail if the object already exists. -M, --modify Find the object somewhere in the CIB's XML tree and update it. Fails if the object does not exist unless -c is specified -P, --patch Supply an update in the form of an xml diff (See also: crm_diff) -R, --replace Recursivly replace an object in the CIB -D, --delete Delete the first object matching the supplied criteria, Eg. <op id="rsc1_op1" name="monitor"/> The tagname and all attributes must match in order for the element to be deleted -d, --delete-all When used with --xpath, remove all matching objects in the configuration instead of just the first one -5, --md5-sum Calculate the on-disk CIB digest -6, --md5-sum-versioned Calculate an on-the-wire versioned CIB digest -S, --sync (Advanced) Force a refresh of the CIB to all nodes -a, --empty Output an empty CIB Additional options: -f, --force -t, --timeout=value Time (in seconds) to wait before declaring the operation failed -s, --sync-call Wait for call to complete before returning -l, --local Command takes effect locally. Should only be used for queries -c, --allow-create (Advanced) Allow the target of a -M operation to be created if they do not exist -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 -A, --xpath=value A valid XPath to use instead of -o -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 -N, --node=value (Advanced) Send command to the specified host EXAMPLES
Query the configuration from the local node: # cibadmin --query --local Query the 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 SEE ALSO: CRM shell, crm(8), crm_shadow(8) AUTHOR
