RHBA-2024:2647 - Bug Fix Advisory

Topic

Updated container images that fix multiple bugs are now available for LVMS
4.15

Description

Logical Volume Manager Storage uses lvm2 through the TopoLVM CSI driver to dynamically provision thin and thick local storage on a cluster with limited resources.

This erratum corrects the following issue:

• Previously, LVMS did not support minimum storage size for PVCs. This can lead to mount failures while provisioning PVCs. With this fix, LVMS supports minimum storage size for PVCs.

The minimum storage size that you can request for each file system type is as follows:

• XFS: 300 MiB
• ext4: 32 MiB
• Block: 8 MiB

If the value of the `requests.storage` field in the `PersistentVolumeClaim` object is less than the minimum storage size, the requested storage size is rounded to the minimum storage size.

If the value of the `limits.storage` field in the `PersistentVolumeClaim` object is less than the minimum storage size, PVC creation fails with an error.

Users of LVMS are advised to upgrade to the latest version of LVMS in
OpenShift Container Platform, which fixes bugs and security vulnerabilities.
