Mariadb service fails to restart with Galera

You are viewing an old version of this question. View the current version here.


I configured Maraidb with Galera on Alma Linux, I have a 3 node cluster. Everything works ok, but when I restart mariadb the service fails.

I tried to start small with just one node as part of the cluster to troubleshoot, but have the same problem. When I move: /etc/my.cnf.d/galera.cnf to /tmp and then restart maraidb it works fine.

Here is an eg of the error:

  1. systemctl restart mariadb Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xeu mariadb.service" for details.

[root@mariadb01 mariadb]# tail -f mariadb.log 2024-06-18 14:26:59 0 [Warning] WSREP: last inactive check more than PT1.5S ago (PT3.50232S), skipping check 2024-06-18 14:27:28 0 [Note] WSREP: PC protocol downgrade 1 -> 0 2024-06-18 14:27:28 0 [Note] WSREP: view((empty)) 2024-06-18 14:27:28 0 [ERROR] WSREP: failed to open gcomm backend connection: 110: failed to reach primary view: 110 (Connection timed out) at /builddir/build/BUILD/galera-26.4.14/gcomm/src/pc.cpp:connect():160 2024-06-18 14:27:28 0 [ERROR] WSREP: /builddir/build/BUILD/galera-26.4.14/gcs/src/gcs_core.cpp:gcs_core_open():221: Failed to open backend connection: -110 (Connection timed out) 2024-06-18 14:27:29 0 [ERROR] WSREP: /builddir/build/BUILD/galera-26.4.14/gcs/src/gcs.cpp:gcs_open():1669: Failed to open channel 'clustera' at 'gcomm:': -110 (Connection timed out) 2024-06-18 14:27:29 0 [ERROR] WSREP: gcs connect failed: Connection timed out 2024-06-18 14:27:29 0 [ERROR] WSREP: wsrep::connect(gcomm: failed: 7 2024-06-18 14:27:29 0 [ERROR] Aborting

Tried re-inialising, and then it works and shows only one clustre rmember (because I only added one to start with whilst troubleshooting): galera_new_cluster

But the moment I restart mariadb it fails again.

Any ideas? Thanks in advance
