Data truncated for column 'VARIABLE_VALUE' at row 1

    XMLWordPrintable

    Details

      Description

      Global variables table from information_schema database variable_value column varchar(2048) doesn't seems to be enough and generates warning "Data truncated for column 'VARIABLE_VALUE'".

      CREATE TEMPORARY TABLE `GLOBAL_VARIABLES` (
      `VARIABLE_NAME` varchar(64) NOT NULL DEFAULT '',
      `VARIABLE_VALUE` varchar(2048) NOT NULL DEFAULT '' 
      

      For instance:

      ssl_cipher  ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384
      ssl_key /etc/my.cnf.d/keys/redacted_server.key
      

      And wsrep_provider_options can't hold it and value truncated for ssl_cipher variable.
