How do I symbollically link 2 directories between 2 SD cards?

[bsp]

Yes I did exactly what you've instructed.  I saw all the scripts in the proper directories but just no "all_roms" folder created anywhere.

My psd1 is max out so I don't know whether this is the problem as the 3 games on psd2 are totalled up more than 2GB.  Could this be the reason why "all_roms" couldn't get created on psd1?

If your SDcard really is that full then you should make some space by deleting/moving some files.


Try running the mount script manually in a terminal window, i.e.


# sudo su
# /home/root/mount_aufs.sh

Are there any error messages ?


What's the output of


# mount
after running the script ?

Here's the output:

Looks like a permission issue.

Yep, that's what I thought. You somehow managed to mess up the permissions of that shell script -- it's not executable anymore, hence the 'Permission denied' message.

Let me guess.. You edited the file as non-root user (e.g. using mousepad), couldn't overwrite the original file so you saved it under a different name, deleted the original file and renamed your modified script.

To fix this, you will have to restore the original permissions.

First of all, take a look at the original permissions:


pandora2:/# tar tvfz /sd1/mmc_insert_script-17Nov2013.tar.gz
-rw-r--r-- root/root       215 2013-11-17 20:47 etc/udev/rules.d/mmc_script.rules
-rwxr-xr-x root/root       106 2013-11-17 21:13 home/root/mmc_insert.sh
-rwxr-xr-x root/root       479 2013-11-17 21:21 home/root/mount_aufs.sh
pandora2:/#
(you'll have to adjust the path to the .tar.gz, of course)

Now take a look at how your current permissions look like:


pandora2:~$ sudo su
Password:
pandora2:/home/bsp# cd /
pandora2:/# ls -ld `tar tfz /sd1/mmc_insert_script-17Nov2013.tar.gz `
-rw-r--r-- 1 root root 215 Nov 17 20:47 etc/udev/rules.d/mmc_script.rules
-rwxr-xr-x 1 root root 106 Nov 17 21:13 home/root/mmc_insert.sh
-rwxr-xr-x 1 root root 594 Nov 19 14:16 home/root/mount_aufs.sh
pandora2:/#

(most likely different than this!)


Now fix the permissions of the mount_aufs.sh script:


pandora2:/# chmod 755 /home/root/mount_aufs.sh
and make sure that they are correct now:

pandora2:/# ls -ld /home/root/mount_aufs.sh
-rwxr-xr-x 1 root root 594 Nov 19 14:16 /home/root/mount_aufs.sh

This fixed it!

Thank you very much for your help as well as patience!

The Pandora is my first encounter with Linux world so please forgive me as I have no clue what you did there but it worked!
