[Pacemaker] node is unable to join cluster after upgrade (crmd dies)

Hi all,
I am using pacemaker/openais and drbd to have a high-available MySQL server which worked „for years“ (sind SLES 11 SP 0) without configuration chances.
Just two days ago I did an update (zypper up) which now leads to the issue described below.
Although the subject of my email is quite similar to many others on this list I could not find an equivalent (so it seems) problem or a solution. I tried to provide as much information as seemed to be reasonable to me so I apologize in advance for the many lines!
Two servers with identical configuration (hard and software) running SLES 11 SP3 (with HAE) have the following crm config:
———————

this worked since the first setup long ago.
after the update (zypper up) two days ago only sql01b is running, sql01a is unable to join the cluster.

Starting the cluster tools on sql01a („rcopenais start“) leads to the following lines (snipped the „OK-looking“ lines at top as I enabled debugging in corosync.conf; if necessary i can of course post the whole output, but that’s a lot of lines ...) in /var/log/messages:

For digging further what’s going wrong I then started the missing processes (cib, attrd, pengine and crmd) from the command line (using the -V switch). cib, attrd and pengine are starting fine (even crm now shows a result, although „wrong“) but crmd fails:

what I tried up to now:
- stop sql01a, remove all cib.xml and crm.xml in their folders and restart sql01a (I know this is quite harsh but what did I have to loose …) -> the config on sql01a has been taken from sql01b but the crmd always dies as before (same error messages)
- I removed all cluster related packages (pacemaker, corosync, drbd, …) from sql01a and deleted the remaining dirs and config files, reinstalled all with copies from sql01b -> same result.
- I removed the whole crm config from sql01b (the working cluster host) using cibadmin -Q —force and re-added the config (using crm „commands") -> same result
- of course rebooted/restarted both servers several times -> nothing changes …
As deleting the config from sql01a (several times) I thought the error must be in the config/communication on/with sql01b but I also removed and added the config there, in addition there is now firewall between them and there is communication.
Does anybody know/understand what is going on here?
How can I solve this issue and get my cluster back to work as it did for quite a long time recently?
thanks in advance for any hints!
best regards,
Markus
