Hi,

We are looking for a method to estimate the size of metadata overhead for a given file system.

We would like to use this value as indicator for the amount of cache memory a system for faster operation.

Are there any counters that are maintained in the on-disk data structuresÂlike free space for examples?

Thank you,

Danny Shavit
