Now I am testing XtraDB Cluster following the URL: [http://www.percona.com/doc/percona-xtradb-cluster/singlebox](http://www.percona.com/doc/percona-xtradb-cluster/singlebox). html
The first one node is working well.
When I tried to start the second node,I met the above error mentioned: Segmentation fault. And I also logged the error information. Please see more as follow:

You could find that there is one warning prompting as above,which is highlighted by myself. I don’t why this file was not created by itself and why there is the additional slash behind the path /data/db/xtradbcluster2/.
Finally back to my puzzle: what could result in “Segmentation fault”?
Thanks and Regards,
Zhang

This might be two different problems. Please file a bug report on Launchpad and paste the URL here so other interested users can find it.

Thank you,Baron.
I already reported a bug on the Launchpad. But I am not sure whether the issue I mentioned here is a real bug and before I got stuck on my process and configuration with more suspicion.
