DVDRom Drive

[mirdragon]

Not sure if posted in correct section, but anyone offer any advice on mounting a dvdrom within freenas to read data from the disc.

This what I have tried so far using the shell

edit /etc/devfs.conf

uncommented the following line and saved the file
#link cd0 dvd

edit /edit/fstab

added the following line and saved this, but on reboot it is removed (also tried with udf instead of iso9660)
/dev/cd0 /media/cdrom0 iso9660 ro,user,noauto 0 0

i then entered 'kldstat' which shows udf.ko installed, which should allow the reading of optical media.

entering 'file -s /dev/cd0' displays

/dev/cd0: # ISO 9660 CD-ROM filesystem data 'GRMCHPXFRER_EN_DVD ' (bootable)

entering 'ls -al /dev/cd*' displays

crw-r----- 1 root operator 0x60 Jul 14 21:34 /dev/cd0

if i then attempt to mount the drive with the following

mount -t cd9660 /dev/cd0 /media/dvdrom it looks as though it has mounted, but when you look at the folder there is a readme.txt, which when you open it, it shows the following

This disc contains a "UDF" file system and requires an operating system that supports the ISO-13346 "UDF" file system specification.

so tried the following without much success

mount -t iso13446 /dev/cd0 /media/dvdrom
mount: /dev/cd0: Operation not supported by device

mount -t udf /dev/cd0 /media/dvdrom
mount_udf: /dev/cd0: Invalid argument

mount_udf /dev/cd0 /media/dvdrom
mount_udf: /dev/cd0: Invalid argument

mount /dev/cd0 /media/dvdrom
mount: /dev/cd0: Invalid argument

Is this an encrypted Blueray disc? Or did you create the disk yourself (if so, using what operating system)?

 

[mirdragon]

No its an official Windows 7 64bit Retail Installation DVD

I want to see if can get the drive mounted and read, so if I manage to install Win7 within the VB environment (without it constantly failing during the install using an iso image) I want to see if this can then pick up the drive for use. If it doesn't I need to look at other options (but don't wish to have to rebuild server to a different operating system)

 

[cyberjock]

FreeNAS may not have the required dependencies to mount disks locally. Basically the thumbrule "if the WebGUI can't do it, it may not be supported" is worth mentioning here. Since you can't mount CD-ROM drives from the WebGUI I wouldn't necessarily expect this to work. I'd say that 99%+ of us don't even have a CD-ROM drive attached to the system (no iXsystems FreeNAS/TrueNAS hardware has CD-ROMs built-in) so I would be pleasantly surprised if it works. ;)

 

[dlavigne]

And to add to cyberjock's response, I would not be surprised if Microsoft adds some sort of DRM to their media which the mount_udf driver does not support.

 

[mirdragon]

this will be a limitation of freenas as the disk is read fine under ubuntu - looks like will probably have to remove freenas and install a different os that can read cd/dvd roms and also work properly with VM's

 

[Ericloewe]

If you just want to install Windows 7 in a VM, just get the ISO (Windows 8 will do that for you, Windows 7 requires third-party tools) and upload it to the server.

 

[mirdragon]

VirtualBox crashes during the install reporting the install has been aborted - if i got this working then i want the operating system I'm using to have full access to all usb ports and the dvd drive (which it looks like VB on Freenas can't do)
