A.5 Anticipating Disk-Space Growth

Anticipating Filr Disk Space Growth

Filrsearch Disk Space Growth

  • The /vastorage disk will see the most growth because this is where the indexes reside.

SQL Disk Space Growth

  • SQL disk space growth is confined to the database (/vastorage on the MySQL appliance).

  • Depending on the current size of /vastorage, you should expand /vastorage to allow for growth as follows:

    1. After synchronizing the first 20 million files, run the following query on the database.

      SELECT  sum(round(((data_length + index_length) / 1024 / 1024 / 1024), 2))  as "Size in GB" FROM information_schema.TABLES  WHERE table_schema = "<database name>"
    2. Based on the results, calculate the disk space required for 100 Million files.

    3. Include anticipated growth that in the total.


  • Set the DB innodb_buffer_pool_size to 66-75% of the total memory available to the appliance.

  • This parameter is set on initial configuration with new installs, but if the HyperVisor guest OS's memory increases, this parameter needs to be manually set in the /etc/my.cnf file.

    In /etc/my.cnf, the exact setting is

    innodb_buffer_pool_size = 2048M

  • The byte specifier is mandatory.

    Setting this to more than the available memory on the system prevents the database from starting.
