Resolution

Please contact SUSE Customer Care to obtain a PTF that resolves the issue.

Cause

When using Cache Tiering, the iSCSI gateway (lrbd) will automatically also add the configured cache pool information to the configuration which is incorrect, resulting in it not being possible to activate lrbd.
