MySQL Percona Cluster: WSREP Error "Failed to initialize backend"
Posted on 2012-08-16
Hello everyone -
I am dealing with another DBA's installation of Percona Cluster this afternoon - and he's not available.
I have searched the forums here and I have failed to find a post regarding the problem I am seeing.
The sysadmin restarted NODE01 and MySQL (Percona Server) is not starting due to:
120816 13:11:33 WSREP: gcs/src/gcs_backend.c:gcs_backend_init():87: Invalid backend URI: 0
120816 13:11:33 WSREP: gcs/src/gcs_core.c:gcs_core_open():202: Failed to initialize backend using '0': -22 (Invalid argument)
120816 13:11:33 WSREP: gcs/src/gcs.c:gcs_open():1290: Failed to open channel 'c_l' at '0': -22 (Invalid argument)
120816 13:11:33 WSREP: gcs connect failed: Invalid argument
120816 13:11:33 WSREP: wsrep::connect() failed: 6
120816 13:11:33 Aborting
That's from the NODE1 error log.
Any idea at all what's going on here?
The system has been previously up and running in a four node arrangement. The other three nodes have MySQL up and running.
Thanks in advance for ANY advice, thoughts or suggestions you may be able to provide.
