dear members of the pacemaker mailing list,
i am using pacemaker on Debian GNU/Linux testing (wheezy) in combination with
LIO [1] and DRBD. The setup heavily relies on [2].
After fiddling around I am able to move the iscsi storage from one
(storage-)node to the other successfully.
With this setup [3] I unfortunately always need to create the lun mapping
manually like this :
/iscsi/iqn.20...:31f4493c3d6c> create mapped_lun=0 tpg_lun=0 Created Mapped LUN
0.
Entering new node
/iscsi/iqn.2012-07.org.linux-iscsi.iscsi-storage.i686:sn.d94bc9daa270/tpgt1/acls/iqn.2012-07.lan.xcp1:01:31f4493c3d6c/mapped_lun0
/iscsi/iqn.20...:31f4493c3d6c> create mapped_lun=0 tpg_lun=0 Created Mapped LUN

Any way to get this working the pacemaker way ?
