Hi,

I’ve upgraded My Percona on 5.5.23.  
The first node start without problem, but the others nodes failed due to errors :

120516 14:57:44 [Warning] WSREP: Failed to prepare for incremental state transfer: Local state UUID (00000000-0000-0000-0000-000000000000) does not match group state UUID (18df8ebb-848f-11e1-0800-34439383ee44): 1 (Operation not permitted)

In the sst.err file:

Error while getting st data from donor node

In innobackup.backup.log file :  
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

Why this pb and how to resolve it

Thx a lot

Have you looked at your /etc/mysql/my.cnf?

I resolve it, you must put in my.cnf file in [MYSQLD] section :  
datadir=/var/lib/mysql  
tmpdir=/tmp  
user=mysql

Be carrefull, you can probably obtain a start/stop failed, so you must update password for mysql user debian-syst-main.  
This password is written in debian.cnf file
