I am using Percona Xtradb Cluster 5.7 and trying to start my cluster through a donor node via command line and I am getting this error: [root@pxc1 mydata]# systemctl start mysql --wsrep\_sst\_donor=pxc3 systemctl: unrecognized option ‘–wsrep\_sst\_donor=pxc3’ I am running 3 nodes cluster. I have started my first node-A with bootstrap, then started second node-B which synced with node-A and now i want my third node-C to sync with the first one node-A as well, but it seems not possible. Is to possible at all to do this on centos7? ---

Hi there, thanks for your question. For someone to help you, and therefore to get quicker attention on the Forum, you have to provide much more information for example my.cnf from every node, any log files that are getting written, is this a new installation or an existing one that is causing trouble, what is the specific version of Percona XtraDB Cluster that you are using, is there anything “special” about your server environment etc etc Without this information it’s hard for engineers to help. Here’s a post that tells you a little more: [URL=“[https://www.percona.com/forums/questions-discussions/percona-xtradb-cluster/50706-troubleshooting-percona-xtradb-cluster-and-how-to-report-a-bug](https://www.percona.com/forums/questions-discussions/percona-xtradb-cluster/50706-troubleshooting-percona-xtradb-cluster-and-how-to-report-a-bug)”][https://www.percona.com/forums/quest...o-report-a-bug[/URL]](https://www.percona.com/forums/quest...o-report-a-bug%5B/URL%5D) If you need help in a specific time scale, then we do offer paid support services. With paid support you get a guaranteed response time. With the open source community forum, then there’s no guarantee of a response, but the more information you provide, the more likely it is that someone will be able to quickly see an issue and help you out. Hope this helps. ---

Somebody has a clue how to start a node of a cluster through a donor with --wsrep\_sst\_donor option? ---

I am sorry, ekonomi, but you cannot expect instant responses from a non-paid forum. If you need fast responses from the Percona team then I am afraid that you will have to pay for support. The Forum should not be mistaken for “free support”. FWIW I have asked the team to look at your question when they have some time but the forum is not their priority. It may be that a community member will help you quicker, or if you need instant help please consider our support options.

It’s funny that you gave a mysqld option “–wsrep\_sst\_donor” to the linux command “systemctl”. you can try startup mysqld manually and try again.

Hi [ekonomi](https://www.percona.com/forums/member/42204-ekonomi), Instead of passing wsrep\_sst\_donor on the command line, you should set the same in the my.cnf of joiner node. [pxc1] vim /etc/my.cnf or the config file in use. [mysqld] … wsrep\_sst\_donor=pxc3 Save my.cnf and start MySQL service, It should use pxc3 as a donor for SST. You can confirm the same from error logs of pxc1 while SST is running. [pxc1] systemctl start mysql Once pxc1 has joined the cluster, you can comment the line “wsrep\_sst\_donor…” if you want. ---
