[OpenAFS] questions about volume size?

[Harald Barth]

> thanks for reply. however, i did not do vos backup. :)

To Sam:

Never created a backup volume?

To the community:

How does this work "under the hood"? I thought, when I make a backup
volume, files are "cloned" with link(2)? Is this the same for Namei
and Inode?

Does not look like it is done like that (all volumes on server pompano
have backup volumes of the same size as the original ones)

pompano# cd /vicepa/AFSIDat/p0/pGj+U/+/+/
pompano# ls -l
total 5624
---------- 1 root root       0 Sep 19 17:27 0++++6
---------- 1 5937 adm  5754336 Sep 19 17:27 2++++A
---------- 1 adm  root    2048 Sep 19 17:27 =++++2

pompano# stat 0++++6 
  File: `0++++6'
  Size: 0               Blocks: 0          IO Block: 4096   regular empty file
Device: fd04h/64772d    Inode: 2417392386  Links: 1
Access: (0000/----------)  Uid: (    0/    root)   Gid: (    0/    root)

So how is it done?
