Chapter 4. Uninstalling OpenShift Data Foundation

4.1. Uninstalling OpenShift Data Foundation in Internal-attached devices mode
Copier lien

Use the steps in this section to uninstall OpenShift Data Foundation.

Uninstall Annotations

Annotations on the Storage Cluster are used to change the behavior of the uninstall process. To define the uninstall behavior, the following two annotations have been introduced in the storage cluster:

uninstall.ocs.openshift.io/cleanup-policy: delete
uninstall.ocs.openshift.io/mode: graceful

The following table provides information on the different values that can used with these annotations:

Expand

Table 4.1. uninstall.ocs.openshift.io uninstall annotations descriptions
Annotation	Value	Default	Behavior
cleanup-policy	delete	Yes	Rook cleans up the physical drives and the `DataDirHostPath`
cleanup-policy	retain	No	Rook does not clean up the physical drives and the `DataDirHostPath`
mode	graceful	Yes	Rook and NooBaa pauses the uninstall process until the administrator/user removes the Persistent Volume Claims (PVCs) and Object Bucket Claims (OBCs)
mode	forced	No	Rook and NooBaa proceeds with uninstall even if the PVCs/OBCs provisioned using Rook and NooBaa exist respectively

Edit the value of the annotation to change the cleanup policy or the uninstall mode.

$ oc -n openshift-storage annotate storagecluster ocs-storagecluster uninstall.ocs.openshift.io/cleanup-policy="retain" --overwrite

$ oc -n openshift-storage annotate storagecluster ocs-storagecluster uninstall.ocs.openshift.io/mode="forced" --overwrite

Expected output for both commands:

storagecluster.ocs.openshift.io/ocs-storagecluster annotated

Prerequisites

Ensure that the OpenShift Data Foundation cluster is in a healthy state. The uninstall process can fail when some of the pods are not terminated successfully due to insufficient resources or nodes. In case the cluster is in an unhealthy state, contact Red Hat Customer Support before uninstalling OpenShift Data Foundation.
Ensure that applications are not consuming persistent volume claims (PVCs) or object bucket claims (OBCs) using the storage classes provided by OpenShift Data Foundation.
If any custom resources (such as custom storage classes, cephblockpools) were created by the admin, they must be deleted by the admin after removing the resources which consumed them.

Procedure

Delete the volume snapshots that are using OpenShift Data Foundation.
1. List the volume snapshots from all the namespaces.
  $ oc get volumesnapshot --all-namespaces
2. From the output of the previous command, identify and delete the volume snapshots that are using OpenShift Data Foundation.
  $ oc delete volumesnapshot <VOLUME-SNAPSHOT-NAME> -n <NAMESPACE>
  <VOLUME-SNAPSHOT-NAME>
  Is the name of the volume snapshot
  <NAMESPACE>
  Is the project namespace
Delete PVCs and OBCs that are using OpenShift Data Foundation.
In the default uninstall mode (graceful), the uninstaller waits till all the PVCs and OBCs that use OpenShift Data Foundation are deleted.
If you want to delete the Storage Cluster without deleting the PVCs, you can set the uninstall mode annotation to forced and skip this step. Doing so results in orphan PVCs and OBCs in the system.
1. Delete OpenShift Container Platform monitoring stack PVCs using OpenShift Data Foundation.
  See Removing monitoring stack from OpenShift Data Foundation
2. Delete OpenShift Container Platform Registry PVCs using OpenShift Data Foundation.
  Removing OpenShift Container Platform registry from OpenShift Data Foundation
3. Delete OpenShift Container Platform logging PVCs using OpenShift Data Foundation.
  Removing the cluster logging operator from OpenShift Data Foundation
4. Delete the other PVCs and OBCs provisioned using OpenShift Data Foundation.
  - Given below is a sample script to identify the PVCs and OBCs provisioned using OpenShift Data Foundation. The script ignores the PVCs that are used internally by OpenShift Data Foundation.
    
    #!/bin/bash RBD_PROVISIONER="openshift-storage.rbd.csi.ceph.com" CEPHFS_PROVISIONER="openshift-storage.cephfs.csi.ceph.com" NOOBAA_PROVISIONER="openshift-storage.noobaa.io/obc" RGW_PROVISIONER="openshift-storage.ceph.rook.io/bucket" NOOBAA_DB_PVC="noobaa-db" NOOBAA_BACKINGSTORE_PVC="noobaa-default-backing-store-noobaa-pvc" # Find all the OCS StorageClasses OCS_STORAGECLASSES=$(oc get storageclasses | grep -e "$RBD_PROVISIONER" -e "$CEPHFS_PROVISIONER" -e "$NOOBAA_PROVISIONER" -e "$RGW_PROVISIONER" | awk '{print $1}') # List PVCs in each of the StorageClasses for SC in $OCS_STORAGECLASSES do echo "======================================================================" echo "$SC StorageClass PVCs and OBCs" echo "======================================================================" oc get pvc --all-namespaces --no-headers 2>/dev/null | grep $SC | grep -v -e "$NOOBAA_DB_PVC" -e "$NOOBAA_BACKINGSTORE_PVC" oc get obc --all-namespaces --no-headers 2>/dev/null | grep $SC echo done
    
    Note
    Omit RGW_PROVISIONER for cloud platforms.
  - Delete the OBCs.
    
    $ oc delete obc <obc-name> -n <project-name>
    
    <obc-name>
    Is the name of the OBC
    <project-name>
    Is the name of the project
  - Delete the PVCs.
    
    $ oc delete pvc <pvc-name> -n <project-name>
    
    <pvc-name>
    Is the name of the PVC
    <project-name>
    Is the name of the project
    Note
    Ensure that you have removed any custom backing stores, bucket classes, etc., created in the cluster.
Delete the Storage System object and wait for the removal of the associated resources.
```
$ oc delete -n openshift-storage storagesystem --all --wait=true
```

Check the cleanup pods if the uninstall.ocs.openshift.io/cleanup-policy was set to delete(default) and ensure that their status is Completed.

$ oc get pods -n openshift-storage | grep -i cleanup

Example output:

NAME                                READY   STATUS      RESTARTS   AGE
cluster-cleanup-job-<xx>        	0/1     Completed   0          8m35s
cluster-cleanup-job-<yy>     		0/1     Completed   0          8m35s
cluster-cleanup-job-<zz>     		0/1     Completed   0          8m35s

Confirm that the directory /var/lib/rook is now empty. This directory is empty only if the uninstall.ocs.openshift.io/cleanup-policy annotation was set to delete(default).

$ for i in $(oc get node -l cluster.ocs.openshift.io/openshift-storage= -o jsonpath='{ .items[*].metadata.name }'); do oc debug node/${i} -- chroot /host  ls -l /var/lib/rook; done

If encryption was enabled at the time of install, remove dm-crypt managed device-mapper mapping from the OSD devices on all the OpenShift Data Foundation nodes.
1. Create a debug pod and chroot to the host on the storage node.
  $ oc debug node/<node-name>
  $ chroot /host
  <node-name>
  Is the name of the node
2. Get Device names and make note of the OpenShift Data Foundation devices.
  $ dmsetup ls
  Example output:
  ocs-deviceset-0-data-0-57snx-block-dmcrypt (253:1)
3. Remove the mapped device.
  $ cryptsetup luksClose --debug --verbose ocs-deviceset-0-data-0-57snx-block-dmcrypt
  Important
  If the above command gets stuck due to insufficient privileges, run the following commands:
  Press CTRL+Z to exit the above command.
  Find PID of the process which was stuck.
  
  $ ps -ef | grep crypt
  
  Terminate the process using kill command.
  
  $ kill -9 <PID>
  
  <PID>
  Is the process ID
  Verify that the device name is removed.
  
  $ dmsetup ls
Delete the namespace and wait till the deletion is complete. You need to switch to another project if openshift-storage is the active project.
For example:
```
$ oc project default
```
```
$ oc delete project openshift-storage --wait=true --timeout=5m
```
The project is deleted if the following command returns a NotFound error.
```
$ oc get project openshift-storage
```
Note
While uninstalling OpenShift Data Foundation, if namespace is not deleted completely and remains in Terminating state, perform the steps in Troubleshooting and deleting remaining resources during Uninstall to identify objects that are blocking the namespace from being terminated.
Delete local storage operator configurations if you have deployed OpenShift Data Foundation using local storage devices. See Removing local storage operator configurations.

Unlabel the storage nodes.

$ oc label nodes  --all cluster.ocs.openshift.io/openshift-storage-

$ oc label nodes  --all topology.rook.io/rack-

Remove the OpenShift Data Foundation taint if the nodes were tainted.
```
$ oc adm taint nodes --all node.ocs.openshift.io/storage-
```
Confirm all the Persistent volumes (PVs) provisioned using OpenShift Data Foundation are deleted. If there is any PV left in the Released state, delete it.
```
$ oc get pv
```
```
$ oc delete pv <pv-name>
```
<pv-name>
Is the name of the PV

Remove the CustomResourceDefinitions.

$ oc delete crd backingstores.noobaa.io bucketclasses.noobaa.io cephblockpools.ceph.rook.io cephclusters.ceph.rook.io cephfilesystems.ceph.rook.io cephnfses.ceph.rook.io cephobjectstores.ceph.rook.io cephobjectstoreusers.ceph.rook.io noobaas.noobaa.io ocsinitializations.ocs.openshift.io storageclusters.ocs.openshift.io cephclients.ceph.rook.io cephobjectrealms.ceph.rook.io cephobjectzonegroups.ceph.rook.io cephobjectzones.ceph.rook.io cephrbdmirrors.ceph.rook.io storagesystems.odf.openshift.io --wait=true --timeout=5m

To ensure that OpenShift Data Foundation is uninstalled completely, on the OpenShift Container Platform Web Console,
1. Click Storage.
2. Verify that OpenShift Data Foundation no longer appears under Storage.

4.1.1. Removing local storage operator configurations
Copier lien

Use the instructions in this section only if you have deployed OpenShift Data Foundation using local storage devices.

Note

For OpenShift Data Foundation deployments only using localvolume resources, go directly to step 8.

Procedure

Identify the LocalVolumeSet and the corresponding StorageClassName being used by OpenShift Data Foundation.
```
$ oc get localvolumesets.local.storage.openshift.io -n openshift-local-storage
```
Set the variable SC to the StorageClass providing the LocalVolumeSet.
```
$ export SC="<StorageClassName>"
```
List and note the devices to be cleaned up later. Inorder to list the device ids of the disks, please follow the procedure mentioned here, See Find the available storage devices.
Example output:
```
/dev/disk/by-id/scsi-360050763808104bc28000000000000eb
/dev/disk/by-id/scsi-360050763808104bc28000000000000ef
/dev/disk/by-id/scsi-360050763808104bc28000000000000f3
```

Delete the LocalVolumeSet.

$ oc delete localvolumesets.local.storage.openshift.io <name-of-volumeset> -n openshift-local-storage

Delete the local storage PVs for the given StorageClassName.

$ oc get pv | grep $SC | awk '{print $1}'| xargs oc delete pv

Delete the StorageClassName.
```
$ oc delete sc $SC
```

Delete the symlinks created by the LocalVolumeSet.

[[ ! -z $SC ]] && for i in $(oc get node -l cluster.ocs.openshift.io/openshift-storage= -o jsonpath='{ .items[*].metadata.name }'); do oc debug node/${i} -- chroot /host rm -rfv /mnt/local-storage/${SC}/; done

Delete LocalVolumeDiscovery.

$ oc delete localvolumediscovery.local.storage.openshift.io/auto-discover-devices -n openshift-local-storage

Remove the LocalVolume resources (if any).

Use the following steps to remove the LocalVolume resources that were used to provision PVs in the current or previous OpenShift Data Foundation version. Also, ensure that these resources are not being used by other tenants on the cluster.

For each of the local volumes, do the following:

Identify the LocalVolume and the corresponding StorageClassName being used by OpenShift Data Foundation.
```
$ oc get localvolume.local.storage.openshift.io -n openshift-local-storage
```
Set the variable LV to the name of the LocalVolume and variable SC to the name of the StorageClass
For example:
```
$ LV=local-block
$ SC=localblock
```

List and note the devices to be cleaned up later.

$ oc get localvolume -n openshift-local-storage $LV -o jsonpath='{ .spec.storageClassDevices[].devicePaths[] }{"\n"}'

Example output:

/dev/sdb
/dev/sdc
/dev/sdd
/dev/sde

Delete the local volume resource.

$ oc delete localvolume -n openshift-local-storage --wait=true $LV

Delete the remaining PVs and StorageClasses if they exist.

$ oc delete pv -l storage.openshift.com/local-volume-owner-name=${LV} --wait --timeout=5m
$ oc delete storageclass $SC --wait --timeout=5m

Clean up the artifacts from the storage nodes for that resource.

$ [[ ! -z $SC ]] && for i in $(oc get node -l cluster.ocs.openshift.io/openshift-storage= -o jsonpath='{ .items[*].metadata.name }'); do oc debug node/${i} -- chroot /host rm -rfv /mnt/local-storage/${SC}/; done

Example output:

Starting pod/node-xxx-debug ...
To use host binaries, run `chroot /host`
removed '/mnt/local-storage/localblock/nvme2n1'

Wipe the disks for each of the local volumesets or local volumes listed in step 1 and 8 respectively so that they can be reused.

List the storage nodes.

oc get nodes -l cluster.ocs.openshift.io/openshift-storage=

Example output:

NAME      STATUS   ROLES    AGE     VERSION
node-xxx  Ready    worker   4h45m  v1.18.3+6c42de8
node-yyy  Ready    worker   4h46m  v1.18.3+6c42de8
node-zzz  Ready    worker   4h45m  v1.18.3+6c42de8

Obtain the node console and execute chroot /host command when the prompt appears.

$ oc debug node/node-xxx
Starting pod/node-xxx-debug …
To use host binaries, run `chroot /host`
Pod IP: w.x.y.z
If you don't see a command prompt, try pressing enter.
sh-4.2# chroot /host

Store the disk paths in the DISKS variable within quotes. For the list of disk paths, see step 3 and step 8.c for local volumeset and local volume respectively.

Example output:

sh-4.4# DISKS="/dev/disk/by-id/scsi-360050763808104bc28000000000000eb /dev/disk/by-id/scsi-360050763808104bc28000000000000ef /dev/disk/by-id/scsi-360050763808104bc28000000000000f3 "
or
sh-4.2# DISKS="/dev/sdb /dev/sdc /dev/sdd /dev/sde ".

Run sgdisk --zap-all on all the disks.

sh-4.4# for disk in $DISKS; do sgdisk --zap-all $disk;done

Delete the openshift-local-storage namespace and wait till the deletion is complete. You will need to switch to another project if the openshift-local-storage namespace is the active project.
For example:
```
$ oc project default
$ oc delete project openshift-local-storage --wait=true --timeout=5m
```
The project is deleted if the following command returns a NotFound error.
```
$ oc get project openshift-local-storage
```

4.2. Removing monitoring stack from OpenShift Data Foundation
Copier lien

Use this section to clean up the monitoring stack from OpenShift Data Foundation.

The Persistent Volume Claims (PVCs) that are created as a part of configuring the monitoring stack are in the openshift-monitoring namespace.

Prerequisites

PVCs are configured to use OpenShift Container Platform monitoring stack.
For more information, see configuring monitoring stack.

Procedure

List the pods and PVCs that are currently running in the openshift-monitoring namespace.

$ oc get pod,pvc -n openshift-monitoring

Use this section to clean up the cluster logging operator from OpenShift Data Foundation.

The Persistent Volume Claims (PVCs) that are created as a part of configuring the cluster logging operator are in the openshift-logging namespace.

Prerequisites

The cluster logging instance should have been configured to use the OpenShift Data Foundation PVCs.

Procedure

Remove the ClusterLogging instance in the namespace.
```
$ oc delete clusterlogging instance -n openshift-logging --wait=true --timeout=5m
```
The PVCs in the openshift-logging namespace are now safe to delete.

Delete the PVCs.
