I have a galera cluster with 3 nodes in QA environement.. There was a abrupt shut down of the nodes and I restarted and bootstrapped the first nodewhich is working fine. The second node when I try to start gives the error , "rsyncd[30958]: unknown module 'rsync_sst-undo_dir' tried from XXX" .
In mysql log :
[Warning] WSREP: 0.0 : State transfer to 1.0 (x) failed: -255 (Unknown error 255) [ERROR] WSREP: /home/buildbot/buildbot/build/gcs/src/gcs_group.cpp:gcs_group_handle_join_msg():1207: Will never receive state. Need to abort.
Not sure what causes this error,
rsyncd[30958]: unknown module 'rsync_sst-undo_dir' tried from XXX systemd[1]: mariadb.service: main process exited, code=killed, status=6/ABRT unknown module 'rsync_sst-undo_dir' "
Any pointers would be very helpful .
Thanks

Try to install mariadb first sudo apt install mariadb-server
After this you can normally use mysql but if you have any error try to reinstall mysql with this command : sudo apt install mysql-server
Mariadb is the same as MySQL it’s just open source project after the buy of MySQL by oracle so an employee have quit MySQL to create a new SGBD with an high compatibility of MySQL.

Why "Galera Cluster" not Start?
How To checking "Connection Time Out"?
There is a Error in your config. After gcom you only use one : like:
wsrep_cluster_address=gcomm://192.168.159.132,192.168.159.135,192.168.159.136
their is an error:
use format as below:
wsrep_cluster_address="gcomm://first_ip,second_ip,third_ip"
The galera configuration looks fine. But you have to provide an extra argument while bootstrapping the first node. Try this:
mysqld --wsrep-new-cluster
For the first node wsrep_cluster_address can be empty. For next nodes you have to provide at least one ip address that is already a part of cluster. But it's a good practice to provide the list of all the nodes that you are going to use. It wont give you any error for mentioning a node in cluster-address which is not present in the cluster yet. So you can use, wsrep_cluster_address=gcomm://192.168.159.132,192.168.159.135,192.168.159.136 for every node.
You are getting "connection timed out" because the node is trying to connect to the other nodes listed in wsrep_cluster_address, which aren't online as this is the very first node in the cluster. So, during bootstrap you should start the first node with empty wsrep_cluster_address :.wsrep_cluster_address='gcomm://'.

but can start mysql service as mysql user, or use mysqld_safe as root can start too. what's wrong?

I found this Code Snippets in the script /etc/init.d/mysqld. but don't know why?
Add this line to /etc/my.cnf in [mysqld] section
explicit_defaults_for_timestamp = 1
Check this link
Since you can start as the mysql user, it is likely you have it currently configured to run as root.
Mysql's reference manual says:
On Linux, for installations performed using a MySQL repository, RPM packages, or Debian packages, the MySQL server mysqld should be started by the local mysql operating system user. Starting by another operating system user is not supported by the init scripts that are included as part of the installation.

At some point my logstash forwarder used to work properly but at some point fail to start with this error message
Failed unmarshalling json: invalid character ']' looking for beginning of value logstash
This message appears only if i run forwarder with this command:
$ /opt/logstash-forwarder/bin/logstash-forwarder -config="/etc/logstash-forwarder"
If i run it as a service it fails without any error message, if i restart the service getting this

...done.
The first time stopped forwarder working i found in syslog this message:

At server side logstash and ES cluster seems to work fine..
I found many similar problems with mine but not any solution.
I've a problem in joining new node to percona xtradbcluster.
here is my log :
I tested the test_sstuser working on honor without any problem .
but in new nodes I get these errors :

how can I solve this problem ?

I had the same issue, with another more message:
WSREP_SST: [ERROR] xtrabackup process ended without creating '/path/to/mysql/xtrabackup_galera_info' (20150108 13:09:23.012)
The issue was that I was using xtrabackup and not xtrabackup-v2 in my /etc/mysql/my.cnf:
wsrep_sst_method = xtrabackup
Setting it to:
wsrep_sst_method = xtrabackup-v2
fixed the issue.
Some recommend not to set this variable.
I had the same issue. The fix is simple, just add the following to my.cnf in the [mysqld] section innodb_log_file_size=48M
(Use whatever size log file you need, 48M is OK for small Dbs)
Then follow the instructions to restart mysql with a new log file size. The basics are (but READ the Manual!) stop mysql remove the ib_logfile* files from /var/lib/mysql restart mysql
Be sure not to be using innodb fast shutdown (read the manual!)
We just experienced this error on 1 node out of a 3-node cluster. Manually rsyncing the /var/lib/mysql from a healthy node (we stopped that node during the rsync to not change files while syncing) to the broken node was what we needed to make it go again.
