      Description

      WSREP XID is stored in the TRX_SYS page at innodb_page_size-3500, which overlaps with rseg undo slots, causing the following kind of error:

      170808 12:51:17 [ERROR] InnoDB: Unable to open undo tablespace './undo30579'.
      170808 12:51:17 [ERROR] Plugin 'InnoDB' init function returned error.
      170808 12:51:17 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
      

      In debug build this could also cause innodb-alter-tempfile,4k,innodb_plugin:
