    Description

      Description of problem:

      Running MicroShift on a system without an lvmd.conf file can end up with the CSI containers in a crash-loop state if the host is not configured with a volume group named "rhel". Since that is not the default name for the volume group when installing RHEL via Anaconda, many users may experience this situation until they explicitly configure the driver.

      Version-Release number of selected component (if applicable):

      4.12 and later

      How reproducible:

      Fairly often

      Steps to Reproduce:

      1. Deploy a stock RHEL RPM-based system without taking any special steps to name the volume group.
2. dnf install microshift
3. systemctl start microshift

      Actual results:

      The pod running lvmd will crash loop.

      Expected results:

      No crashing pods.

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
