Changing pool information

Understand how to use the RESTful plug-in to change pool information.

Changing pool information using the curl command

On the command line, run the following command:
echo -En '{"=OPTION": VALUE}' | curl --request PATCH --data @- --silent --user USER 'https://CEPH_MANAGER:8080/api/pool/ID'
Replace:
  • OPTION with the option to modify.
  • VALUE with the new value of the option.
  • USER with the username.
  • CEPH_MANAGER with the IP address or short hostname of the node with the active ceph-mgr instance.
  • ID with the ID of the pool listed in the pool field.
Enter the user’s password when prompted.
Note: If using a self-signed certificate, use the --insecure option.
echo -En '{"=OPTION": VALUE}' | curl --request PATCH --data @- --silent --insecure --user USER 'https://CEPH_MANAGER:8080/api/pool/ID'

Changing pool information using Python

In the Python interpreter, enter the following:
$ python
>> import requests
>> result = requests.patch('https://CEPH_MANAGER:8080/api/pool/ID', json={"OPTION": VALUE}, auth=("USER", "PASSWORD"))
>> print result.json()
Replace:
  • CEPH_MANAGER with the IP address or short hostname of the node with the active ceph-mgr instance.
  • ID with the ID of the pool listed in the pool field.
  • OPTION with one of the modifying options: pause, noup, nodown, noout, noin, nobackfill, norecover, noscrub, or nodeep-scrub.
  • VALUE with true or false.
  • USER with the username.
  • PASSWORD with the user’s password.
Note: If using a self-signed certificate, use verify=False.
$ python
>> import requests
>> result = requests.patch('https://CEPH_MANAGER:8080/api/pool/ID', json={"OPTION": VALUE}, auth=("USER", "PASSWORD"), verify=False)
>> print result.json()
