NAS - Shared file storage appliance. - Implementation

Base Class

The LUX5 appliance image is used as the base class for NAS appliance.

Class Volumes

NAS uses a 120MB boot volume and a 170MB usr (read-only,shared) volume. An additional placeholder volume data is required for shared file storage.

Contents of the NAS directory

• /appliance/appliance.sh is the main NAS startup script. This calls all the scripts that start services running on NAS.
• /appliance/getlogdir.pl - prints a full path to the log dir specified in the 'log_dir' property.
• /appliance/http_load.sh - starts apache service on the http terminal.
• /appliance/nfs_load.sh - starts nfs service.
• /appliance/smb_load.sh - starts samba service.
• /appliance/start_rsyncd.sh - starts rsyncd (only if configured as slave).

Theory of Operation

Samba 3.0 is used to provide cifs service on the cifs terminal.

NFS kernel server is used to provide nfs service on the nfs terminal.

Apache 2.2 is used to provide http access on the http terminal.
