ossfs's Issues

ossfs使用的疑问

我在使用ossfs过程中，遇到一些错误。但是项目中并没有相关Usage文档，我不知道是否是由于不正确使用导致的错误。下面是我的环境和使用方法，还请帮忙指出如何正确使用ossfs。谢谢。

Env:

Aliyun ECS Ubuntu 14.04.3 LTS

我通过以下命令mount existing OSS bucket

sudo ./ossfs -i the-id -k the-key --host oss-cn-beijing-internal.aliyuncs.com -b my-bucket -d  /mnt/oss

执行ossfs命令后，发现ossfs并没有在后台运行，而是运行在前台。如果加上&把ossfs放在后台运行，但发现mountpoint /mnt/oss没有被mount上。

当ossfs在前台执行的时候，得到以下默认输出，

could not find ParserDetails.ini in /usr/local/share/perl/5.18.2/XML/SAX
Use of uninitialized value in subroutine entry at /usr/local/lib/perl/5.18.2/Fuse.pm line 147.

   max_write=0x00020000
   max_background=0

   unique: 1, success, outsize: 40

但当我执行ls /mnt/oss的时候，得到类似下面的错误，

LOOKUP /a2cd8518-4079-415d-b18f-83665f6553b4

ls能够列出bucket下面的文件夹，但无法访问这些文件夹。
