Galera node on Ubuntu 14.04 Trusty not joining after update to MariaDB 10.0.34
Wednesday - Apr 25th 2018 - by - (0 comments)

After having updated a Ubuntu 14.04 Trusty server, including MariaDB and Galera packages, I noticed the node wasn't able to join the Galera cluster anymore.

According to the apt history log, the versions were updated like this:

mariadb-galera-server:amd64 (10.0.31+maria-1~trusty, 10.0.34+maria-1~trusty),  mariadb-client-core-10.0:amd64 (10.0.32+maria-1~trusty, 10.0.34+maria-1~trusty), mariadb-common:amd64 (10.0.32+maria-1~trusty, 10.0.34+maria-1~trusty), mariadb-galera-server-10.0:amd64 (10.0.31+maria-1~trusty, 10.0.34+maria-1~trusty), galera-3:amd64 (25.3.20-trusty, 25.3.22-trusty),  mariadb-client-10.0:amd64 (10.0.32+maria-1~trusty, 10.0.34+maria-1~trusty)

I know for a fact that an automatic join after a MariaDB/MySQL start worked. But after the upgrade and an automatic MariaDB start, the Galera node wasn't able to join the Galera cluster. It appeared in the "wsrep_incoming_addresses" but then quickly disappeared again. In the logs I found the following logs when I manually launched the mysql_safe daemon:

Huh? So this file has changed with the update. On a still working (and not updated yet) node:

Checking the mentioned line 397:

391 if [[ ! ${WSREP_SST_OPT_ROLE} == 'joiner' && ! ${WSREP_SST_OPT_ROLE} == 'donor' ]];then
392     wsrep_log_error "Invalid role ${WSREP_SST_OPT_ROLE}"

403 INNOBACKUP="${INNOBACKUPEX_BIN} ${WSREP_SST_OPT_CONF} \$INNOEXTRA --galera-info --stream=\$sfmt \${TMPDIR} 2>\${DATA}/innobackup.backup.log"

Comparing with line 397 in the old version of the script on node-1:

387 check_extra()
388 {
389     local use_socket=1
390     if [[ $uextra -eq 1 ]];then
391         if $MY_PRINT_DEFAULTS -c $WSREP_SST_OPT_CONF mysqld | tr '_' '-' | grep -- "--thread-handlin    g=" | grep -q 'pool-of-threads';then
392             local eport=$($MY_PRINT_DEFAULTS -c $WSREP_SST_OPT_CONF mysqld | tr '_' '-' | grep -- "-    -extra-port=" | cut -d= -f2)
393             if [[ -n $eport ]];then
394                 # Xtrabackup works only locally.
395                 # Hence, setting host to 127.0.0.1 unconditionally.
396                 wsrep_log_info "SST through extra_port $eport"
397                 INNOEXTRA+=" --host=127.0.0.1 --port=$eport "
398                 use_socket=0
399             else
400                 wsrep_log_error "Extra port $eport null, failing"
401                 exit 1
402             fi
403         else
404             wsrep_log_info "Thread pool not set, ignore the option use_extra"
405         fi
406     fi
407     if [[ $use_socket -eq 1 ]] && [[ -n "${WSREP_SST_OPT_SOCKET}" ]];then
408         INNOEXTRA+=" --socket=${WSREP_SST_OPT_SOCKET}"
409     fi
410 }

Erm yes, that's obviously quite a big difference. Also the sizes of the two scripts (see above) differ.

By replacing the new version of the script with the old script, the node was able to join the cluster again after another MariaDB start:

There seems to be a bug already opened for this issue (https://jira.mariadb.org/browse/MDEV-15254?attachmentViewMode=list) but this is about MariaDB 10.1.x and not 10.0.x as in my case on Ubuntu 14.04 so I opened https://jira.mariadb.org/browse/MDEV-16032.
