I am building a two node active/passive cluster supporting
iSCSITarget,iSCSILogicalUnit and ocf:linbit:drbd. I can hard power down a
primary node (i.e. pull the power cord ) and all my resource migrate correctly
to the other node. However, if I try to migrate the resoruces, put an active
node in standby or shut a system down gracefully DRBD compalains to the console
that drbd0 is held open by someone (it is wanting to switch to
seocndary/secondary) . I followed the example here:
http://www.drbd.org/users-guide/s-pacemaker-crm.html and converted resources
from filesystem to iscsi. I can not figure out what is wrong with my order or
colocation statements. I tried every permutaition of ordering that I could
think of. Both systems are running debian/sid with corosync version 1.2.1
and pacemaker version loaded from the debian repository. The kernel is version
2.6.34 with liotarget support built in. Any help that any could provide would
be greatly appreciated. Thank you. Here is my config:
