- -E, --erase

- -B, --bump
- Increase the CIB's epoch value by 1
- -C, --create
- Create an object in the CIB. 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

- -R, --replace
- Recursively replace an object in the CIB
- -D, --delete

- -d, --delete-all

- -l, --local

- -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
