When I attempt to startup the 3th node, I met this error: ```auto 2022-01-13T08:03:32.978322Z 0 [Note] [MY-000000] [WSREP-SST] Proceeding with SST......... 2022-01-13T08:03:33.036563Z 0 [Note] [MY-000000] [WSREP-SST] ............Waiting for SST streaming to complete! 2022-01-13T08:12:38.715388Z 0 [Note] [MY-000000] [Galera] Created page /mysql/pxc/data/gcache.page.000000 of size 592621440 bytes 2022-01-13T08:12:51.193262Z 0 [ERROR] [MY-000000] [WSREP-SST] Killing SST (27632) with SIGKILL after stalling for 120 seconds 2022-01-13T08:12:51.217686Z 0 [Note] [MY-000000] [WSREP-SST] /usr/bin/wsrep_sst_xtrabackup-v2: line 183: 27634 killed socat -u openssl-listen:4444,reuseaddr,cert=/mysql/pxc/data//server-cert.pem,key=/mysql/pxc/data//server-key.pem,cafile=/mysql/pxc/data//ca.pem,verify=1,retry=30 stdio 2022-01-13T08:12:51.217754Z 0 [Note] [MY-000000] [WSREP-SST] 27635 | /usr/bin/pxc_extra/pxb-8.0/bin/xbstream -x 2022-01-13T08:12:51.218372Z 0 [ERROR] [MY-000000] [WSREP-SST] *******************FATAL ERROR********************** 2022-01-13T08:12:51.218550Z 0 [ERROR] [MY-000000] [WSREP-SST] Error while getting data from donor node: exit codes: 137 137 2022-01-13T08:12:51.218628Z 0 [ERROR] [MY-000000] [WSREP-SST] Line 1268 2022-01-13T08:12:51.218722Z 0 [ERROR] [MY-000000] [WSREP-SST] ****************************************************** 2022-01-13T08:12:51.219631Z 0 [ERROR] [MY-000000] [WSREP-SST] Cleanup after exit with status:32 2022-01-13T08:12:51.431617Z 0 [ERROR] [MY-000000] [WSREP] Process completed with error: wsrep_sst_xtrabackup-v2 --role 'joiner' --address '10.230.245.214' --datadir '/mysql/pxc/data/' --basedir '/usr/' --plugindir '/usr/lib64/mysql/plugin/' --defaults-file '/etc/my.cnf' --defaults-group-suffix '' --parent '27097' --mysqld-version '8.0.23-14.1' '' : 32 (Broken pipe) 2022-01-13T08:12:51.431820Z 0 [ERROR] [MY-000000] [WSREP] Failed to read uuid:seqno from joiner script. 2022-01-13T08:12:51.431892Z 0 [ERROR] [MY-000000] [WSREP] SST script aborted with error 32 (Broken pipe) 2022-01-13T08:12:51.432257Z 3 [Note] [MY-000000] [Galera] Processing SST received 2022-01-13T08:12:51.432372Z 3 [Note] [MY-000000] [Galera] SST request was cancelled 2022-01-13T08:12:51.432458Z 3 [ERROR] [MY-000000] [Galera] State transfer request failed unrecoverably: 32 (Broken pipe).

My PXC cluster is 8.0.23, now there are 2 nodes running in CentOS 7. ---

Your log indicates that port 4444 is not open TCP/UDP to all hosts. Make sure all necessary ports (3306, 4444, 4567, 4568) are open between all nodes. ---

Thanks for your reply, but I am sure I have closed firewall between all nodes. Maybe there is some other issues? ---

> [@liking](#): > > I am sure I have closed firewall between all nodes That’s your problem. You need to OPEN the firewall between nodes, not close it. Use `socat` or `nc` to test connectivity between nodes on the ports I mentioned. ---

I will post the final result when I finished doing this. But now I met some trouble, wait some days. ---

It is ok now. According to your suggest, I modified the netfilter rules on all nodes like this: 1. Accept all input 2. Clear all netfilter rules ```auto [root@db-1 ~]# iptables -P INPUT ACCEPT [root@db-1 ~]# iptables -F [root@db-1 ~]# iptables -X [root@db-1 ~]# iptables -Z [root@db-1 ~]# iptables -A INPUT -i lo -j ACCEPT [root@db-1 ~]# iptables-save # Generated by iptables-save v1.4.21 on Mon Jan 24 11:33:23 2022 *filter :INPUT ACCEPT [884:105489] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [685:162312] -A INPUT -i lo -j ACCEPT COMMIT # Completed on Mon Jan 24 11:33:23 2022 ``` Now the cluster works fine. Thank you again!
