Repositories

The SMB repository plugin has been removed from core, it is in contrib at the moment: http://tracker.moodle.org/browse/CONTRIB-1103

This plugin is not stable when you accessing a large files collection by smb, the web server may be stopped by it.

However, I created a new repository plugin called "file system", which can implement similar functionality, http://tracker.moodle.org/browse/MDL-18520.

1. Enable file system plugin and set up your local repository, say:
/home/dongsheng/smaba_dir

2. mount smaba host
mount -t cifs -o username=xxx,password=xxx //samba_host/samba_dir /home/dongsheng/samba_dir

3. done, alternatively, you can use sshfs to load other remote folder.
