Hi!

For a new EU project we want to setup a OpenAFS cell.
As we could hit some limitations of OpenAFS, I would like to collect all
known limitations of current OpenAFS systems (1.5.70 on windows and
1.4.11 on linux that is).
I know of:

- -one RW copy of a volume
- -max 6 RO copies from one volume
- -max 256 fileservers in one cell
- -max 64k slots for filenames in one directory
- -ACLs on directories only
- -quota only on volumes

Are those still correct?

Some limitations were open:
- -max number of volumes per cell/fileserver?
- -max number of ACL entries in a directory?
- -max numbers of "supergroup feature" includes?
- -max number of db servers in one cell?

Thank you.

MfG,
Lars Schimmer
