[周韬 <zho...@16...>]

Hello wirter,I'm teddy! I study MFS now,have some question want to ask you!
MooseFS  version:1.6.20-2
Fuse version:8.5
All operating system are CentOS 5.5_64
All file system are ext3
1、When I use snapshost and take a snapshost,the snapshost size is same as source directory or file,next is my step:
[root@localhost floder]# du -sh u.img
20M     u.img
[root@localhost floder]# /usr/local/mfs/bin/mfsappendchunks u.img.bak u.img
[root@localhost floder]# ll
total 2114278
-rw-r--r-- 1 root root     654246 Jun 30 01:14 mfs-1.6.20-2.tar.gz
-rw-r--r-- 1 root root  524288000 Jun 30 02:27 teddy500M
-rw-r--r-- 1 root root 1073741824 Jun 30 02:18 test1G
-rw-r--r-- 1 root root  524288000 Jun 30 02:19 test500M
-rw-r--r-- 1 root root   20971520 Jun 29 10:13 u.img
-rw-r--r-- 1 root root   20971520 Jun 30 18:57 u.img.bak
-rw-r--r-- 1 root root     105311 Jun 30 01:14 zlib-devel-1.2.3-4.el5.x86_64.rpm
[root@localhost floder]# du -sh u.img.bak
20M     u.img.bak
use the mfsmakesnapshost result is same the mfsappendchunks!
2、When i mount at the client,have some wong messages at the system log,what is the mean?but i can use as normal;
[root@localhost floder]# tail -f /var/log/messages
