- Not a total answer to your question, but maybe a step in the right
- direction. As I have gathered from information on the AFS mailing
- list AFS reserves a fixed part of the disk when formatting it. This
- part of the disk is used for directory and file headers. If you only
- have a few large files on your disk much of this space will be unused
- (wasted?). For now the amount of header space is a fixed fraction of the
- total disk/partition size and cannot be configured. FFS manages disk space
- in a very different way and current disk info programs calculate disk info
- data according to the FFS algorithm which is not very proper for AFS disks.
