[Pacemaker] Dont start LVM or FS on DRBD Standalone

[Pierre BLONDEAU]

Hi,

I can't find how to configure pacemaker to don't put drbd on primary
mode when one of my nodes is standalone.

If i have a standalone drbd server. The second start and became
standalone. So pacemaker can put the second node primary and start lvm,
iscsi, etc ... And i have a split-brainwith my data.

My goal isn't to stop the lvm, the iscsi, etc. ... when a node enters
standalone mode, just don't run in primary mode at startup and so don't
start the lvm, the iscsi, etc. ...

Thank you in advance for your answers
Regards
