Linux Help

[Gremlin]

I am not a Linux admin by any means. 

 

I have installed Linux on a virtual machine. In that VM i have added three hard drives let's say 100GB, 200GB and 300 GB which are VM's as well. 

 

So when you go into linux and do fdisk -l you will see 

 

/dev/sdb pointing to 100GB

/dev/sdc pointing to  200GB

/dev/sdd pointing to 300GB

 

format it and everything works fine as it is supposed to. Now when the machine is rebooted, drives get swapped like for example:

 

/dev/sdb pointing to 200GB

/dev/sdc pointing to  300GB

/dev/sdd pointing to  100GB

 

I would like it to be as it was before when it was originally started. 

 

In the /etc/fstab, I mapped/mounted the drives using the UUID of the drives and it still swaps. I am trying to make it work with udev and rules.d.

 

I have been googling since yesterday to find out if there is any other way.

 

Can someone please provide any help would really appreciate it 

 

Thank you

It's probably an issue with your VM program? 

[Gremlin]

yes .. finally figured it out you can't do it on a vmware machine..

 

run this command : udevadm info -a -n /dev/sdb | more

 

and you get this output as below : 

 

looking at device '/devices/pci0000:00/0000:00:15.1/0000:04:00.0/host3/target3:0:0/3:0:0:0/block/sdb':

    KERNEL=="sdb"

    SUBSYSTEM=="block"

    DRIVER==""

    ATTR{range}=="16"

    ATTR{ext_range}=="256"

    ATTR{removable}=="0"

    ATTR{ro}=="0"

    ATTR{size}=="419430400"

    ATTR{alignment_offset}=="0"

    ATTR{discard_alignment}=="0"

    ATTR{capability}=="52"

    ATTR{stat}=="     390        1     3128       97        0        0        0        0        0       97       97"

    ATTR{inflight}=="       0        0"

 

  looking at parent device '/devices/pci0000:00/0000:00:15.1/0000:04:00.0/host3/target3:0:0/3:0:0:0':

    KERNELS=="3:0:0:0"

 

Booting depends on the value of this line :  KERNELS=="3:0:0:0"

 

Example you add a  disk into a new OS, run the above command.. and check the value of the KERNELS. If it is 3, and you reboot it will be fine.. If the value is any other than 3, it will get swapped on reboot...

 

oh well

Try VirtualBox...it's probably slightly better about drive mapping.
