mysql - Percona Xtradb集群 : Error while getting data from donor node

Question

我在将新节点加入 percona xtradbcluster 时遇到问题。

这是我的日志:

我测试了在 honor 上工作的 test_sstuser 没有任何问题。

但在新节点中我得到这些错误:

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)

我该如何解决这个问题？

最好的问候

我有同样的问题，还有一条消息:

WSREP_SST:[错误] xtrabackup 进程在未创建 '/path/to/mysql/xtrabackup_galera_info' (20150108 13:09:23.012) 时结束

问题是我在 /etc/mysql/my.cnf 中使用的是 xtrabackup 而不是 xtrabackup-v2:

wsrep_sst_method                        = xtrabackup

将其设置为:

wsrep_sst_method                        = xtrabackup-v2

解决了这个问题。

有些人建议不要设置这个变量。
