Is LVM cluster-aware? Of course it's not, but... Will I loose data if I 
have a LVM physical volume replicated on two machines with DRBD, and I 
want to access two separate logical volumes on different machines?


Machine_1
          \            /--Logical_volume_1
           DRBD-LVM2-PV
          /            \--Logical_volume_2
Machine_2


On Machine_1 I only want to read/write to Logical_volume_1.
On Machine_2 I only want to read/write to Logical_volume_2.

I don't want to add/remove/rename/resize/etc. any volumes - just access 
them on separate machines.


Perhaps the answer is: yes, you will loose your data, but I wanted to be 
sure ;)

Are there any workarounds to that (with just two volumes it's simple - 
don't use LVM; but let's suppose there are many logical volumes)?
