ext2

I have an ext2 filesystem with a maximum number of inodes per directory (somewhere around 32k), and also a maximum number of inodes in the entire filesystem (somewhere around 350m). Because I'm using this filesystem as a datastore for a service that has in excess of 32k objects, I'm distributing those objects between multiple subdirectories (like a dictionary separates A-K and L-Z).

My question is this:

Is there any significance to the tree depth when I'm building these inodes? Is there a significant difference or limitation that's going to affect my service if I choose "/usr/www/service/data/a_k/aardvark" over "/data/a_k/aardvark"?

Remove a file on linux using the inode number

as seen on Super User - Search for 'Super User'
If you create a file on UNIX/linux with special chars, like touch \"la*, you can't remove it with rm "la*. You have to use the inode number(you can if you add the \ before the name, I know, but you'd have to guess as a user that it was used in the file creation). I checked the manpage for rm, but… >>> More
