Description Josef Zimek 2021-01-14 10:07:55 UTC

Description of problem:

Resource type ocf:ceph:rbd is provided by ceph package (/src/ocf/rbd.in) and supports following options:

  name (required): Name of the RBD device.
  pool: Name of the RADOS pool where the RBD has been created
  snap: Name of the device snapshot to map.
  cephconf: Location of the Ceph configuration file
  mon: Address (or comma-separated list of addresses) of monitor servers to connect to. Overrides values from configuration file.
  user: Username to use when mapping the device. Required if Ceph authentication is enabled on the monitor.
  secret: File containing an authentication secret. Required if Ceph authentication is enabled on the monitor.


However if user utilizes ceph cluster with rbd pool and namespaces he/she cannot create resource with namespace and therefore resource doesn't work.

Add support of "namespace" parameter for ocf:ceph:rbd resource type.


Version-Release number of selected component (if applicable):
ceph-12.2.7-9.el8

Comment 2 Jason Dillaman 2021-01-21 21:40:33 UTC

Resetting to RHCS product / RBD component as this OCF resource agent is distributed under RHCS via the "ceph-resource-agents" package.

Comment 6 Harish Munjulur 2021-03-13 19:32:53 UTC

Verified the RFE. Steps followed are as below:

[ceph: root@magna021 ~]# ceph osd pool application enable rbd rbd
enabled application 'rbd' on pool 'rbd'
[ceph: root@magna021 ~]# rbd pool init -p rbd
[ceph: root@magna021 ~]# rbd namespace ls
[ceph: root@magna021 ~]# rbd namespace create --namespace testnamespace
[ceph: root@magna021 ~]# rbd namespace create --namespace othernamespace
[ceph: root@magna021 ~]# rbd namespace ls --format=json

Comment 9 Harish Munjulur 2021-03-15 19:11:17 UTC

package missing have raised BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1939231

Comment 12 Harish Munjulur 2021-03-31 19:46:29 UTC

Verified working as expected: change in the below command "namespace" should be "pool_namespace"

# pcs resource create rbd_map_gsitlani ocf:ceph:rbd user=“admin” pool=“rbd” name="test-rbd" cephconf=“/etc/ceph/ceph.conf” pool_namespace="node1" op monitor interval=“10s” timeout=“20s”

Thanks gsitlani++ for the help with steps.
