Wait a min, what if file size truncation happens the other way round? Thats meta-data.

Metadata self-heal is happening only from server 1 to server 2 even if it supposed to be self-healing the other way. 

# touch dot
# ls -l dot 
-rw-r--r-- 1 root root 0 2010-07-27 16:42 dot

# kill server1
# chmod -R 777 dot 
# ls -l dot 
-rwxrwxrwx 1 root root 0 2010-07-27 16:42 dot

# server1 start
# find . | xargs stat > /dev/null
# ls -l dot 
-rw-r--r-- 1 root root 0 2010-07-27 16:42 dot

Needed option metadata-changelog on which is now on by default in mainline.
