    Description

      1. Format and mount a new filesystem
      2. copy some file in it
      3. umount the filesystem
      4. mount it again

      The file lost their contents.

      If 'sync' is executed between 2 and 3, the issue is gone. Looks like umount has not flushed dirty data.

          llmountcleanup.sh is using 'umount -f' to umount client, which will not flush back dirty data.

          I was using llmount.sh and llmountcleanup.sh for mount and umount.
