  • Maximum Directory Size (maxdirsize)

Answer

Maxdirsize is a volume level option that limits the maximum size to which a directory file can grow.

  • Maxdirsize determines the number of files a directory can hold.
  • The default maxdirsize is 320MB. (The default value is 320 MB, which allows you to store up to 4.3 million files in each directory)
  • Most environments do not need to change this setting

The default value of 320MB can be increased as necessary.

  • It is recommended not to configure the size larger than necessary, as certain directory operations require the entire directory to be memory resident.
  • And once the maxdirsize is increased, it cannot be reduced without recreating the directory.
