xtrabackup SST error

dseiradseira EntrantCurrent User Role Beginner

I'm trying the Percona XtraDB Cluster for testing purpose. I've used the wsrep_sst_method with rsync and mysqldump options, and works correctly.

The problem comes when I want to try the xtrabackup method for avoid the blocking tables problem. I don't know why, but the node can't go up, it shows me a failed message. The mysql error log shows the next output:

It shows a problem with tar program and SST failed. I've defined the wsrep_sst_method as xtrabackup and wsrep_sst_auth as root:XXXX.

I don't know which is the problem? Anyone can help me?

    right to check my.cnf
  • dseiradseira Entrant Current User Role Beginner
    This is my my.cnf:


    I put the wsrep_sst_auth for authenticate the user correctly but it doesn't work.

    Any idea?

    In my case, I had to change sst method to rsync from xtradbackup-v2

    Yes, try wsrep_sst_method=xtrabackup-v2
