Thanks for your reply. I have added the "-d" option when calling the fuse_dfs, but I can't see any stack traces. The ONLY thing I see on the console is: port=54310,server=10.15.62.4 fuse-dfs didn't recognize /mnt/dfs,-2 fuse-dfs ignoring option -d fuse-dfs ignoring option -o fuse-dfs didn't recognize allow_other,-2 fuse: invalid argument `allow_other'
The option "-d" is ignored. Maybe there is something wrong in my building step. Can anyone help me? Thanks.
