Percona Xtradbcluster: error while receiving data from donor node

Question

I have a problem connecting a new node to percona xtradbcluster.

here is my magazine:

I tested test_sstuser working on honor without any problems.

but in the new nodes I get the following errors:

2014-05-31 04:01:40 2391 [Warning] WSREP: Failed to prepare for incremental state transfer: Local state UUID (00000000-0000-0000-0000-000000000000) does not match group state UUID (02dc9b38-e825-11e3-a67b-4bfddfde0c98): 1 (Operation not permitted)

How can I solve this problem?

Answer 1

I had the same problem. The fix is ​​simple, just add the following to my.cnf in the [mysqld] innodb_log_file_size = 48M section

(Use whatever size log file you need, 48M is fine for small Dbs)

mysql . ( READ the Manual!) mysql ib_logfile * /var/lib/mysql restart mysql

, innodb ( !)

Answer 2

, :

WSREP_SST: [ERROR] xtrabackup process ended without creating '/path/to/mysql/xtrabackup_galera_info' (20150108 13:09:23.012)

, xtrabackup, xtrabackup-v2 /etc/mysql/my.cnf:

wsrep_sst_method                        = xtrabackup

:

wsrep_sst_method                        = xtrabackup-v2
