InnoDB: "Cannot open <ib_buffer_pool file>" should not be an error

    XMLWordPrintable

Details

    Description

      In InnoDB 5.7 innodb_buffer_pool_load_at_startup has become ON by default. Now InnoDB produces an error when it starts and doesn't find the dump of the buffer pool. 

      2017-01-19 13:51:49 140427969689344 [ERROR] InnoDB: Cannot open '/data/bld/10.2/data/ib_buffer_pool' for reading: No such file or directory

      It can happen, for example, on upgrade from a previous version.
      But in fact the situation is harmless, so it shouldn't be an error – a warning, at most.
