I wanted to follow this guide in setting up a new node to be added to the cluster. [url][http://www.percona.com/blog/2012/08/02/avoiding-sst-when-adding-new-percona-xtradb-cluster-node/[/url]](http://www.percona.com/blog/2012/08/02/avoiding-sst-when-adding-new-percona-xtradb-cluster-node/%5B/url%5D) After installing XtraBackup from apt, ```auto found out that the MySQL service was stopped. Tried running the service again using ``` or ```auto service mysql start ``` but it still won’t start. No error feedback after running the command. I also don’t see any errors being generated in the logs after running the command. From the logs (I believe after installing XtraBackup): ```auto ... clip ... ``` Is the issue with MySQL service not starting a direct result of installing XtraBackup? Why? ---

Why did you specify? PXC 5.6 requires Xtrabackup 2.2.x. See what happens when I try to install this old version on my test debian box: ```auto root@vagrant-debian-wheezy:~# dpkg -l|grep -i perc |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ii percona-xtrabackup 2.2.5-5027-1.wheezy amd64 Open source backup tool for InnoDB and XtraDB ii percona-xtradb-cluster-client-5.6 5.6.20-25.7-886.wheezy amd64 Percona XtraDB Cluster database client binaries ii percona-xtradb-cluster-common-5.6 5.6.20-25.7-886.wheezy amd64 Percona XtraDB Cluster database common files (e.g. /etc/mysql/my.cnf) ii percona-xtradb-cluster-galera-3.x 3.7.3256.wheezy amd64 Galera components of Percona XtraDB Cluster ii percona-xtradb-cluster-server-5.6 5.6.20-25.7-886.wheezy amd64 Percona XtraDB Cluster database server binaries root@vagrant-debian-wheezy:~# apt-get install percona-xtrabackup-21 Reading package lists...

Need to get 8,521 kB of archives. After this operation, 64.8 MB disk space will be freed. Do you want to continue [Y/n]? ``` Basically, if I would agree, PXC will be removed. I suggest to read the apt messages more thoroughly in the future.
