Just to that this issue is applicable only for one of the resource group,
even the conf is the same for both of them!

So, after hours of running the same test again and again, and reading 100000
lines of logs (BTW it seams that they say in a clear way why certain things
happen) I decided to recreate the drbd_01 and ms-drbd_01 resource and adjust
the order constraints
before it was like this
order fs_01-after-drbd_01 inf: ms-drbd_01:promote fs_01:start
order fs_02-after-drbd_02 inf: ms-drbd_02:promote fs_02:start
order pbx_01-after-fs_01 inf: fs_01 pbx_01
order pbx_01-after-ip_01 inf: ip_01 pbx_01
order pbx_02-after-fs_02 inf: fs_02 pbx_02
order pbx_02-after-ip_02 inf: ip_02 pbx_02

and now like this
order fs_02-after-drbd_02 inf: ms-drbd_02:promote fs_02:start
order pbx_02-after-fs_02 inf: fs_02 pbx_02
order pbx_02-after-ip_02 inf: ip_02 pbx_02
order pbx_service_01-after-drbd_01 inf: ms-drbd_01:promote
pbx_service_01:start*
*
as you can see no major changes.

The end result is that now every time I issue "crm resource move
pbx_service_01 node-0N" the drbd_01 is promoted on that node as well and the
whole resource group is started! So, issue is solved but I don't like it for
the very simple reason, I don't why it didn't work, and that scares me!

Cheers,
Pavlos
