1. Format and mount a new filesystem 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. |

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

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