GFS2 file system fails to unmount and reports "Unmount seems to be stalled. Dumping lock state..." in RHEL 5
Issue
- When I shutdown or reboot my node, it hangs on unmounting file systems with the error "Unmount seems to be stalled. Dumping lock state..."
- The filesystem would not unmount and the following error was emitted to the console:
kernel: GFS2: fsid=SCCL01:SCCL01PAPEFS.6: Unmount seems to be stalled. Dumping lock state...
