Hi,

I install Percona 5.5.24, I can’t start my node 2 and node 3.  
I have this error message in innobackup.backup.log :

xtrabackup: Error: Please set parameter ‘datadir’  
innobackupex: fatal error: no ‘mysqld’ group in MySQL options  
innobackupex: fatal error: OR no ‘datadir’ option in group ‘mysqld’ in MySQL options

I don’t understand because I set datadir.

[mysqld]  
port=3306  
socket=/var/run/mysqld/mysqld.sock  
datadir=/var/lib/mysql  
tmpdir=/tmp  
user=mysql  
local-infile=0…

I find the problem  
this is because rights my.cnf file was in 600 instead of 644
