This section describes how to find and clean stale subvolumes.
Before you begin
Important: Deleting stale subvolumes using the ODF CLI tool is a Technology Preview
feature and is subject to Technology Preview limitations.
Download the OpenShift Data Foundation command-line interface (CLI) tool. With the Data
Foundation CLI tool, you can effectively manage and troubleshoot your Data Foundation environment
from a terminal. To get a compatible version and download the CLI tool, see customer portal.
About this task
Sometimes stale subvolumes do not have a respective k8s reference attached.
These subvolumes are of no use and can be deleted. You can find and delete stale subvolumes using
the ODF CLI tool.
Procedure
- Find the stale subvolumes by using the --stale flag with the
subvolume command:
Example output:
# Filesystem Subvolume Subvolumegroup State
# ocs-storagecluster-cephfilesystem csi-vol-427774b4-340b-11ed-8d66-0242ac110004 csi stale
# ocs-storagecluster-cephfilesystem csi-vol-427774b4-340b-11ed-8d66-0242ac110005 csi stale
- Delete the stale subvolumes:
odf subvolume delete <subvolumes> <filesystem> <subvolumegroup>
Replace <subvolumes> with a comma separated list of subvolumes from the
output of the first command. The subvolumes must be of the same filesystem and subvolumegroup.
Replace <filesystem> and <subvolumegroup> with the
filesystem and subvolumegroup from the output of the first command.
Example:
odf subvolume delete csi-vol-427774b4-340b-11ed-8d66-0242ac110004,csi-vol-427774b4-340b-11ed-8d66-0242ac110005 ocs-storagecluster csi
Example output:
# Info: subvolume csi-vol-427774b4-340b-11ed-8d66-0242ac110004 deleted
# Info: subvolume csi-vol-427774b4-340b-11ed-8d66-0242ac110004 deleted
