High Volume File System Question
 

Hello,

I have been a linux user for over a decade but am coming across an issue I havent had to deal with before and would love some input.

I have a need to store many individual small files (under 1mb) in individual folders. I have read ext4 allows 64,000 directories in a sudirectory. So if I am reading this right,

I have directory /A and /B and they both can have 64,000 subdirectories? Can each of their subdirectroies also have 64,000 children?

If one is to have literally thousands of small files and folders is there a better FS than ext4? Reiser? Opinions are very welcome here.

Thanks!

I recommend JFS or XFS or any other filesystem that uses B+ tree allocation. This removes any limits for number of files.

ext* doesn't use B+ tree allocation, and so there is a limit.
