RHEL7, internal IPv6 networking, 3 node Galera cluster
-
5.5.59
Description
Configured internal IPv6 networking for galera cluster replication. First node creates new cluster successfully, but 2nd node is unable to join cluster when attempts SST rsync. Attached server.cnf is my /etc/my.cnf.d/server.cnf file.
After I fixed the wsrep_sst_rsync script (in code shown below), the 2nd node successfully joined the cluster over IPv6.
Here is the excerpt from /var/log/messages:

This is a bug in the following code in teh wsrep_sst_rsync script that doesn't support IPv6 format address:
ADDR=$WSREP_SST_OPT_ADDR
|
RSYNC_PORT=$(echo $ADDR | awk -F ':' '{ print $2 }') |
if [ -z "$RSYNC_PORT" ] |
then |
RSYNC_PORT=4444
|
ADDR="$(echo $ADDR | awk -F ':' '{ print $1 }'):$RSYNC_PORT" |
