ClearCase dynamic view storage on BTRFS does not work correctly

Troubleshooting


Problem

On SUSE Linux Enterprise Server 12 after Service Pack 2 inclusive (SLES12 SP2+), and SUSE Linux Enterprise Server 15, if you create a dynamic MVFS view and set the view storage directory to a BTRFS file system with the snapshot feature active, then some operations like 'cleartool deliver' might enter into an uninterruptible state (or hang).

Symptom

Some processes running on the system cannot be killed with 'kill' or interrupted with Ctrl+C.
