wsrep_sst_rsync does not support innodb_data_home_dir

    XMLWordPrintable

Details

    Description

      If you have an entry in your configuration file like this:

      innodb_data_home_dir=/innodbdata

      Then rsync SSTs will fail.

      The first time a joiner attempts to SST, the node will see log entries like this, showing that a new InnoDB data file is being created after the SST:
