Mint 12 Mount Error: While Experimenting

[drajc07]

Hi All,

First I wanted to apologize if this topic already has been covered in earlier postings (did a quick search and did not find anything). Today I decided to experiment with Mount options via the Gnome Mate drive utility in the Control Center.

I went to the area of mount permissions (ownership) clicked on group access to mount (did this for all of my partitions (including separate / partition)) and initially I entered ‘Admin’ as the group for all of my partitions (/var /usr /opt /swap /home) but checked the listing of groups and realized that the group name is not ‘Admin’ but 'admin'.

I changed all of the mount group access permissions to 'admin'. I rebooted my system after installing some unrelated software and that is when I found out that the change for my ‘/’ partition did not get saved. BTW I am using the ‘XFS’ file system.

In the reboot process system halted and gave the following error:

 udevd [343]: Specified group ‘Admin’ unknown.
Mountall:  Mount / [849]: Permission denied.

I even tried to enter recovery mode via grub menu option and got this error (in addition to the one above):

Could not find whiptail, starting root shell instead of Recovery Menu.

I then pressed CTRL D as requested and entered my password; but did not know to proceed.

I was wondering if there is a way to fix this problem I got myself into without reinstalling Mint (Lisa)?

If So, can someone give me detailed instructions on how to solve this. It would greatly be appreciated.

BR,

Daniel R.

boot from a live CD/pen drive, then mount relevant partitions and make changes as required ... if your changing permissions on filesystems it may also be worth chrooting into the system ...
