Subject fuse-dfs:fuse-dfs didn't recognize /dfs,-2
Date Fri, 09 Oct 2009 06:35:25 GMT

Hi, 

I get the following error when trying to mount the fuse dfs,

the first problem is:
[root@puppet ~]# fuse_dfs_wrapper.sh dfs://100.207.100.25:9000/ /dfs
port=9000,server=100.207.100.25
fuse-dfs didn't recognize /dfs,-2

the second problem is:
then i cd /dfs,
[root@puppet dfs]# ls -l
total 0
?--------- ? ? ? ?            ? n:9000/1
?--------- ? ? ? ?            ? n:9000/tmp
?--------- ? ? ? ?            ? n:9000/user

when use -d option,like
[root@puppet ~]# fuse_dfs_wrapper.sh dfs://100.207.100.25:9000/ /dfs -d
port=9000,server=10.207.0.25
fuse-dfs didn't recognize /dfs,-2
fuse-dfs ignoring option -d
