Comment 2 for bug 1431101

@Jervin,

Yes, with a $DATADIR/.sst/backup.my.cnf, this can occur.

The .sst directory can only exist if a previous SST failed, and it is not removed as follows:

        wsrep_log_info "Moving the backup to ${TDATA}"
        timeit "Xtrabackup move stage" "$INNOMOVE"
        if [[ $? -eq 0 ]];then
            wsrep_log_info "Move successful, removing ${DATA}"
            rm -rf $DATA
            DATA=${TDATA}
        else
            wsrep_log_error "Move failed, keeping ${DATA} for further diagnosis"
            wsrep_log_error "Check ${DATA}/innobackup.move.log for details"
        fi
