If I manually dismount or detach SR then snapshots can be takened successfully. However dismount or detach does not always work. It shows device is busy and I can't see any PID is using it by fuser. So my questions are: 1. Why snapshot SRs sometime randomly are left mounted when there is no snapshot activities? 2. What is the way to clean up the above SR mounts? My environment is CS 4.0.1 and XS 6.0.2 with all hot fixes up-to-date. Thanks! Yong
