rook ceph cleanup

You can add the Multus network attachment selection annotation selecting the created network attachment definition on selectors. The rook-ceph-agent pods are responsible for mapping and mounting the volume from the cluster onto the node that your pod will be running on.
Again, it is only helpful to provision a DB device if it is faster than the primary device. Rook waits for the deletion of PVs provisioned using the cephCluster before proceeding to delete the cephCluster. The complete list of labels in hierarchy order from highest to lowest is: For example, if the following labels were added to a node: For versions previous to K8s 1.17, use the topology key: or region. To determine the size of the metadata block follow the official Ceph sizing guide. Verify that the cluster CRD has been deleted before continuing to the next step. Similarly, nodes are only removed if the node is removed from the Ceph The following CephCluster CR represents a cluster that will perform management tasks on the external cluster. If an admin does not know of an endpoint that fits this critera, the admin can find such an endpoint on the remote Ceph cluster (via the tool box if it is a Rook Ceph Cluster) by runnning: A list of endpoints in the master zone group in the master zone is in the endpoints section of the JSON output of the zonegoup get command. To test this run the curl command on the endpoint: Finally add the endpoint to the pull section of the CephObjectRealm’s spec. Without proper cleanup, pods consuming the storage will be hung indefinitely until a system reboot. The cluster will then provision a Persistent Volume (PV) if one matches the requirements of the PVC. This guide assumes a Rook cluster as explained in the Quickstart. Individual nodes and their config can be specified so that only the named nodes below will be used as storage resources. For a list of trademarks of The Linux Foundation, please see our For the example realm, the uid for the system user is “realm-a-system-user”. If a usable node comes online, Rook will rook-csi-rbd-provisioner NOTE: Placement of OSD pods is controlled using the Storage Class Device Set, not the general placement configuration. This will begin the process of the Rook Ceph operator and all other resources being cleaned up. Changes made to the resource’s configuration or deletion of the resource are not reflected on the Ceph cluster. This field is optional. To change the defaults that the operator uses to determine the mon health and whether to failover a mon, refer to the health settings. When a ceph-object-store is created without the zone section; a realm, zone group, and zone is created with the same name as the ceph-object-store. To control how many resources the Rook components can request/use, you can set requests and limits in Kubernetes for them. If a node does not specify any configuration then it will inherit the cluster level settings. It includes the following keys: mgr, mon, osd, cleanup, and all.

The Rook toolbox can modify the Ceph Multisite state via the radosgw-admin command.
If you want to tear down the cluster and bring up a new one, be aware of the following resources that will need to be cleaned up: Note that if you changed the default namespaces or paths such as dataDirHostPath in the sample yaml files, you will need to adjust these namespaces and paths throughout these instructions. POOL_NAME USED OBJECTS CLONES COPIES MISSING_ON_PRIMARY UNFOUND DEGRADED RD_OPS RD WR_OPS WR USED COMPR UNDER COMPR Dual-stack is not supported by ceph. Because Check the result with ceph osd tree from the Rook Toolbox. OSDs created prior to Rook v0.9 or with older images of Luminous and Mimic are not created with ceph-volume and thus would not support the same features. © Rook Authors 2020. For example, you could change the mgr probe by applying: Changing the liveness probe is an advanced operation and should rarely be necessary. Multisite configuration must be cleaned up by hand. supported and will result in a non-functioning cluster. NOTE: Kubernetes version 1.13.0 or greater is required to provision OSDs on PVCs. that all SSD devices should be data disks and two of the NVMe devices should be wal/db disks for the All files under the dataDirHostPath property specified in the cluster CRD will need to be deleted. IMPORTANT: When managing a Rook/Ceph cluster’s OSD layouts with Drive Groups, the storage These are general purpose Ceph container with all necessary daemons and dependencies installed. As mentioned above, you would need to inject the admin keyring for that. When A specific will contain a specific release of Ceph as well as security fixes from the Operating System. The Rook Ceph operator creates a Job called rook-ceph-detect-version to detect the full Ceph version used by the given cephVersion.image.

Rook will no longer use storage configs for creating OSDs on a node’s devices. If any setting is unspecified, a suitable default will be used automatically. name: rook-ceph-block-ext. In the other scenario, there are more than one zones in a zone group. For more information on the multisite CRDs please read ceph-object-multisite-crd. registered trademarks and uses trademarks.
