Option for mounting additional local disks

[igno2k]

batocera-boot.conf has the option to mount full /userdata or single directories (like /userdata/roms) via NAS.

Example:

  sharedevice=NETWORK
  sharenetwork_smb1=ROMS@192.168.0.1:Documents/batocera/roms:guest

It would be nice to have a similar option in batocera-boot.conf for additional local disks. For example having two hard disks

• HDD1: contains batocera installation and /userdata/ (fast flash drive)
• HDD2: contains only rom files (UUID abcdefg-1234-5678-hijk-lmnopq0000) ("slow" mass storage)

HDD2 should be mounted to /userdata/roms while the rest of the /userdata resides on HDD1.

Maybe it can be done with a configuration like this:

  sharedevice=INTERNAL
  sharedevice_hdd1=ROMS@abcdefg-1234-5678-hijk-lmnopq0000

This can also be done for separate hard disks or partitions for SAVES, BIOS, etc.

I think only some changes to /etc/init.d/S11share have to be done.

At the moment this could also be accomplished with a "dirty hack" like (not tested yet):

sharedevice=NETWORK
sharenetwork_cmd1=mount -t ext4 UUID=abcdefg-1234-5678-hijk-lmnopq0000 /userdata/roms

What do you think?

yes, seems easy to add and nice.
i add it to my todo.

Thanks a lot!
Just for the record: the "dirty hack" I mentioned works fine but the other solution would be much cleaner.

[nadenislamarre]

done here : #5974
please feedback with the next beta soon.

syntax :

sharedevice=DEVICES

sharedevice_part1=SHARE@abcdefg-1234-5678-hijk-lmnopq0000

sharedevice_part2=ROMS@68dc61b8-5008-4659-bde9-5938a547680a:/Documents/roms

note that the device can be a simple uuid or uuid:subdirectory which could be nice to mount /windows/users/you/my_roms for example.

Thanks a lot!
Will check it this weekend and give feedback.

Are there any restrictions regarding filesystems? I will test it with ext4 - but maybe a lot of users have external disks used alongside Windows with ExFAT/NTFS filesystem.

[nadenislamarre]

hum, i use mount instead of batocera-mount , so yes, i should change it while the aim of batocera-mount is to handle them

[igno2k]

Ok, tested it today with an extern USB drive with ext4 filesystems used for ROMS. Works perfectly fine with latest beta (build date 14.04.2022).

Thanks!

Interesting discussion. I would have a different need and that is, I have Batocera installed on a 2TB SATA HDD, on which I have run out of space. I would like to mount a 2nd STATA HDD on the Motherboard and configure Batocera to make it read the ROMS folder, both from HDD1 and HDD2: can this be done? Thank you.
