DATA sharing problem for additional distros in a Win7 - LL2 dual boot system

[gold_finger]

However I experienced a problem with binding two more ubuntu-based distros on sda, in addition to the  LL2, and Win 7 on sda, to bind with /mnt/DATA on sdb. The two additional distros wont bind, though Win7 and LL2 remain successfully bound.

Is the presence of Win7 making the binding exclusive, i.e. it will only allow one other distro to share /mnt/DATA with it?

Strange!  I don't have a computer that dual-boots with Windows, but I highly doubt Windows is the cause of the problem.  Not sure what is going wrong, so just going to have you post back a bunch of command output and answers to a few questions that might give us a clue.  Hopefully we can figure it out from there.

What are the other two OSs that you are giving you the problems?

Boot into one of them and post back following info from it (let us know which OS you're using for this):

1.  Copy of bind-home.conf file being used.

2.  Are the problem OSs the same two other distros that you have on the computer with working set-up?

3.  Copy/Paste full terminal output from these commands:

Code: [Select]

id
lsblk
sudo blkid -c /dev/null
cat /etc/fstab
cat /etc/mtab

I originally had a multiple boot system with the operating systems of 4 distros on sda (all based on ubuntu), while the swap area and shared DATA partition were on sdb.  This worked well.  I then decided to set (up on 2nd laptop a Win 7 - LL2 dual boot): again a separate shared DATA partition was set up to allow filesharing between Windows 7 & LL2. Again this is worked well,  binding both "My_Documents" in win7 and the Directories in  /home of LL2 to the separate /mnt/DATA partition. 

However I experienced a problem with binding two more ubuntu-based distros on sda, in addition to the  LL2, and Win 7 on sda, to bind with /mnt/DATA on sdb. The two additional distros wont bind, though Win7 and LL2 remain successfully bound.

I have checked the "bind-home.conf" files that I created for the two additional distros but these look fine, as well as the /etc/fstab files that were set up.

When I try to mount /mnt/DATA, using the terminal, I get the following message for either additional distro:


m-z9@z9-AsusX71Q:~$ sudo mount /dev/sdb1 /mnt/DATA
[sudo] password for m-z9:
Mount is denied because the NTFS volume is already exclusively opened.
The volume may be already mounted, or another software may use it which
could be identified for example by the help of the 'fuser' command.

Is the presence of Win7 making the binding exclusive, i.e. it will only allow one other distro to share /mnt/DATA with it? Wondered if anyone else had experienced this and if there is a way around it?  I have no experience of the fuser command and what this means. 

Many thanks in advance for any help with this.
Kind regards
