Can I revert the maxdirsize value to a smaller value?

Applies to

• ONTAP 9
• Data ONTAP operating in 7-Mode
• Directory size (maxdirsize)

Answer

Yes, the maxdirsize options can be set to a lower value. But it should be not reduced to a value lower than the current largest directory in the volume. 

• Reducing the maxdirsize value does not shrink existing directory size.
• Once a directory size is grown, it cannot be reduced without recreating the directory.

Note: It is highly recommended NOT to modify the maxdirsize settings due to the potential performance impact !!! Review the following:

• What are the performance impacts of changing the size of maxdirsize?
• What directory structure should I use to avoid maxdirsize issues?
• Does deleting files in a directory cause the directory size to reduce?
