[Pacemaker] Problems with colocation/order with drbdtree-node-setup

[Schmidt, Torsten]

i think there is a problem with the monitor operation for the stacked drbd resouce:

after erase + commit of my crm-config the CIP and mysqldb (lower) resource started on node 2

so i looked at drbd-status on node 2 and there was nothing to be seen of the stacked device:

/proc/drbd
--------------------------------------------------------------------
 0: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r----
    ns:0 nr:30 dw:30 dr:0 al:0 bm:1 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:0
--------------------------------------------------------------------


ptest -L -VVVVV -s -a:
--------------------------------------------------------------------
info: res.drbd.mysqldb:0_monitor_0 on mysqlHA2 returned 0 (ok) instead of the expected value: 7 (not running)
notice: Operation res.drbd.mysqldb:0_monitor_0 found resource res.drbd.mysqldb:0 active on mysqlHA2
info: res.drbd.mysqlstack:0_monitor_0 on mysqlHA2 returned 6 (not configured) instead of the expected value: 7 (not running)
ERROR: Hard error - res.drbd.mysqlstack:0_monitor_0 failed with rc=6: Preventing ms.drbd.mysqlstack from re-starting anywhere in the cluster
info: res.drbd.mysqlstack:0_monitor_0 on mysqlHA1 returned 6 (not configured) instead of the expected value: 7 (not running)
ERROR: Hard error - res.drbd.mysqlstack:0_monitor_0 failed with rc=6: Preventing ms.drbd.mysqlstack from re-starting anywhere in the cluster 
WARN: native_color: Resource res.drbd.mysqlstack:0 cannot run anywhere
--------------------------------------------------------------------

output of crm_mon see below.

im i correct that i only have to load the drbd kernel-module on node 1 + 2; pacemaker should do the rest (configuration, promote/demote...) right?

the 'simple' ptest now is:
---------------------------------------------------------------------------------------------------------
ERROR: unpack_rsc_op: Hard error - res.drbd.mysqlstack:0_monitor_0 failed with rc=6: Preventing ms.drbd.mysqlstack from re-starting anywhere in the cluster

perhaps ptest -L -s -VVVVV helps...
