It seems like a pretty non-standard directory structure layout, hence the problems. Is there one or more MySQL/PXC instances on the same box? I can see dirs /db02, /db04, /db05… Can you share the configs? ---

The configuration is based on MOCA ([url][http://mysql-dba-journey.blogspot.de/2013/04/best-practices-for-installing-mysql-moca.html[/url]](http://mysql-dba-journey.blogspot.de/2013/04/best-practices-for-installing-mysql-moca.html%5B/url%5D)). Software, data and logfiles are seperated on different disks. Two instances are running on the box: one one port 3306, the other on port 3307. ---

Configs attached. “mysql56-01” and “mysql56-02” are the names of the instances. [configs.zip](https://forums.percona.com/uploads/short-url/oAEmxynBNpvOC1BLw5tjVwEmeFT.zip) (9.29 KB) ---

Your configs are very confusing. You use different main directories for the same instance parts, like /db02/ and /db05/, etc. 🙂 Anyway, I can’t see the [url][Index of wsrep system variables](http://www.percona.com/doc/percona-xtradb-cluster/5.5/wsrep-system-index.html#wsrep_sst_receive_address%5B/url%5D) set in wsrep.cnf, try using it. Also this may be helpful: [url][Percona XtraDB Cluster](http://www.percona.com/doc/percona-xtradb-cluster/5.6/howtos/singlebox.html%5B/url%5D) ---

Thanks, i’ll give it a try. /db02 and /db05 are not different instances. /db02 is for datafiles (from instance 1 and 2), /db03 for binlogs, etc. At Oracle it is called “OFA”. You put datafile, logfiles and software installtion on different hdds for a better performance. So /dbx are hdds, not instances. 😉 I’ve installed the cluster on two new testing hosts with default directory structure (everything into /var/lib/mysql) and it’s working. I guess splitting the files into different directories is not supported 'til now. ☹
