Hello everybody,
I was switching from tgtd to lio as iscsi target and hitting some issues.
I have to manually run the targetcli command after the pacemaker
resources are started successfully:
/iscsi/iqn.20....iscsi0/tpgt1> luns/ create /backstores/iblock/iscsi0_lun0
to get the mappings right... what is wrong with my pacemaker config?
see my attachment or http://paste.debian.net/hidden/d5523f15/
also changing lun="1" to lun="0" in the iSCSILogicalUnit did not seem to
change the workings.
Kind regards,
Jelle de Jong
