What does the "etc" mean?  Do you have the following:

LV        Node
----       ------
1    ---> node1
2    ---> node2

This will not work without something more exotic like DRBD.  What you
should do is have each LV presented to ALL nodes.  You want:

LV        Node
----       ------
1    ---> node1, node2
2    ---> node1, node2

I think this might be the root of all of your problems.

Yes.  It does not work otherwise.

>if yes what determine the active node

Nothing.  It is not an active/standby filesystem, it is a clustered
filesystem meaning all the nodes have it mounted simultaneously.

Probably the device /dev/sdb is not the same logical volume on both
nodes.  Search the archives of this list.  Sunil of Oracle posted a
command that you run against the device that gives you a unique serial
number or whatever for each LV so you can tell if they are the same
device.
