FS limits

[Alet Barnard]

Hi

I have the following request from a client:

Please assist in identifying file system directory limits for Tru64 Unix (and HP-UX).

We are running Tru64 v5.1B and using AdvFS but the question was wider.. If you can point me towards the right documentation, it will be greatly appreciated. I have looked at the AdvFS manuals and there seem to be no limitations (like in the previous versions)?

Here is the path: www.hp.com -> software -> OS: Tru64 -> Documentation

The quickspecs have the limits.

V5.1B file system:

Since 5.0 and later the AdvFS uses a b-tree index method for directories. Most AdvFS limits, including directories are just limited by the physical resources (CPU power, memory) you can make available. No hard limits. You will be in a lot of (performance) trouble before you get close to limits. For example, you may be able to stick 10,000,000 files in one directory, but it hurst getting there!

hth,
