Could somebody give us some help on this? We have a file in Lustre 
filesystem shows different behavor from two different client nodes:

On one client node **ds1**, it shows the correct size and its content is 

[root at ds1 ~]# ls -l /lqcdproj/djholm/nHYPBSM/VOV473.note
-rw-r--r-- 1 djholm g023 102 Oct  2 08:06 

On another node ***lqcdsrm***, the filesize is zero and its content is 

[root at lqcdsrm ~]# ls -l /lqcdproj/djholm/nHYPBSM/VOV473.note
-rw-r--r-- 1 djholm g023 0 Oct  2 08:06 /lqcdproj/djholm/nHYPBSM/VOV473.note

I checked the files wrote late under the same directory and it seems 
fine and I can view its content on the same node showing the strange 
behavor (lqcdsrm). There is no ldlm errors during around the time the 
file was written on both the client node and the OSS. We are using 1.8.8.

Thanks in advance for any help on this.
