Cluster does not execute INSERT and UPDATE, many "wsrep in pre-commit stage"

Hi,

we have a cluster with 3 nodes. Everything worked fine until now. All nodes are up, but they do not execute INSERTs, UPDATEs. SELECTS are executed. How do we get the cluster back to work?

Regards

I did some more investigation. The “SHOW ENGINE INNODB STATUS” shows many locked tables. But still no idea what to do… We can access the servers without any problem.

I stopped node 3 and restarted it. Now it makes a full SST (why?). This may take a while… A few queries have been executed, but now node 1 and 2 are still stuck.

One of our programmers created a new table and inserted some data (5 MB). Does this lock the whole cluster??

Ok, the cluster is still blocked. We have to take it down. What causes the cluster to fail like that?

What kind of table was that? What is the “show create table tablename\G”.
You need to provide at least the output of

show status like 'ws%';

and relevant error log parts to help you on that.
