I will try this method to see if there will be effective.

I'm sorry that I didn't  capture the outputs, today I try to replay the 
issue again,
and use "xfs_repair" to repair filesytem, but this time it seems that the
filesystem is not repaired successfully, but it still can be used for a 
while.
Here is the output of xfs_repair :

~ # /mnt/xfs_repair -n /dev/md0
        - creating 2 worker thread(s)
Phase 1 - find and verify superblock...
        - reporting progress in intervals of 15 minutes
Killed

 I haven't found any patch of this issue.
 Athough  I find some patches related to this problem from the web,
it has already been applied in my linux kernel.   I have no way to try the 
recent
kernel, because our embeded system is based on Marvell development board,
and if I use the recent kernel,  the Marvell's patch of this kernel is 
required.
