Hi, I upgrade my PXC in 5.5.28 but I have a problem with wsrep\_cluster\_address variable for multiple addresses in the first node. With wsrep-url, my values was : wsrep\_url = gcomm://ip\_node2:4567,gcomm://ip\_node3:4567,gcom:// How can I apply this values with wsrep\_cluster\_address. At the moment I put like this : wsrep\_cluster\_address = gcomm://,ip\_node2:4567,ip\_node3:4567. The problem is if I restart the first node is in like a split brain, the wsrep\_cluster\_size’s equal to 1 instead to 3. And the others nodes are equal to 2. Thx for your help Best regards ---

Hi, wsrep\_cluster\_address syntax doesn’t require the port (and should be in [mysqld] and not in [mysqld\_slave], just to confirm). So could you try with (I put some random ip’s): wsrep\_cluster\_address=gcomm://192.168.70.2,192.168.70.3 And watch out the first comma in your setting, this is incorrect, with wsrep\_cluster\_address, you don’t have anymore the empty gcomm:// so you need to start the first time your cluster with: wsrep\_cluster\_address=gcomm:// and then modify that setting in my.cnf and never have the empty gcomm anymore (until all your nodes are off) regards, ---

Hi, Thanks for your help but my cluster is in service for a long time. I’m afraid if I stop all nodes and I want restart first node it doesn’t work with your second config modification How can I obtain like this wsrep\_urls= gcomm://192.168.60.12:4567,gcomm://192.168.60.13:4567,gcomm: // but with wsrep\_cluster\_address variable Best regards, ---

Hi lefred, have you find a solution for my problem, because my first node is crashed impossible to start it. So it’s impossible to start PXC on my 2 and 3 node. With this upgrade I lose my HA availability because multiple adress function doesn’t work Best regards ---

The only solution you currently have is: in my.cnf, set something like : wsrep\_cluster\_address=gcomm://192.1.1.1,192.1.1.2,192.1.1.3 and the first node that you will start you need (it works on redhat like distro, no idea yet on debian like) to start the first node like this : /etc/init.d/mysql start --wsrep-cluster-address=“gcomm://”
