Chapter 3. Using odf-cli command

Displays the recovery-profile value set for the OSD. By default, an empty value is displayed if the value is not set using the odf set recovery-profile command. After the value is set, the appropriate value is displayed.

Example:

Checks the health of the Ceph cluster and common configuration issues. This command checks for the following:

In mirroring-enabled clusters, fetches the connection status of a cluster from another cluster. The cephblockpool is queried with mirroring-enabled and If not found will exit with relevant logs.

Example:

$ odf get dr-health

Info: fetching the cephblockpools with mirroring enabled
Info: found "ocs-storagecluster-cephblockpool" cephblockpool with mirroring enabled
Info: running ceph status from peer cluster
Info:   cluster:
    id:     9a2e7e55-40e1-4a79-9bfa-c3e4750c6b0f
    health: HEALTH_OK

[...]

Checks and fetches the status of all the prerequisites to enable Disaster Recovery on a pair of clusters. The command takes the peer cluster name as an argument and uses it to compare current cluster configuration with the peer cluster configuration. Based on the comparison results, the status of the prerequisites is shown.

Example

$ odf get dr-prereq peer-cluster-1

Info: Submariner is installed.
Info: Globalnet is required.
Info: Globalnet is enabled.


odf get mon-endpoints
Displays the mon endpoints
$ odf get dr-prereq peer-cluster-1

Info: Submariner is installed.
Info: Globalnet is required.
Info: Globalnet is enabled.

Sets the provided property value in the rook-ceph-operator config configmap

Example:

$ odf operator rook set ROOK_LOG_LEVEL DEBUG

configmap/rook-ceph-operator-config patched

where, ROOK_LOG_LEVEL can be DEBUG, INFO, or WARNING

Restarts the Rook-Ceph operator

Example:

$ odf operator rook restart

deployment.apps/rook-ceph-operator restarted

Restores the mon quorum when the majority of mons are not in quorum and the cluster is down. When the majority of mons are lost permanently, the quorum needs to be restored to a remaining good mon in order to bring the Ceph cluster up again.

Example:

$ odf restore mon-quorum c

Restores the deleted Rook CR when there is still data left for the components, CephClusters, CephFilesystems, and CephBlockPools. Generally, when Rook CR is deleted and there is leftover data, the Rook operator does not delete the CR to ensure data is not lost and the operator does not remove the finalizer on the CR. As a result, the CR is stuck in the Deleting state and cluster health is not ensured. Upgrades are blocked too. This command helps to repair the CR without the cluster downtime.

Example:
