[OpenAFS] vos release problem

[Derrick J Brashear]

I suspect I know the change that caused it, and unfortunately it's a
legitimate bug fix, which means fixing it exposed some other problem which
is actually causing this.

The bug has actually been on my "active" queue on and off recently but I
wasn't aware anyone else was seeing it.

The bugfix, incidentally, is this:
http://www.openafs.org/cgi-bin/wdelta/STABLE12-volser-ros-use-parent-id-20030512
and what it fixes is a case where *sometimes* a file would get the wrong
salvage dirhandle set and thus fail to be associated with the correct
volumeid.

Thank you for the simpler test case. Hopefully I will have an answer soon.

> could someone please review the following problem
> (OpenAFS 1.2.10, i386_linux24):
>
> - create a volume at fileserver A (vos create)
> - mount it and create a file within the volume (touch)
> - define fileserver A as replica site (vos addsite)
> - define fileserver B as a second replica site (vos addsite)
> - create the replicas (vos release)
> - create a second file within the volume (e.g. modify the content of
>   the volume's root directory - touch)
> - re-create the replicas (vos release)
> - look into the RO volume, make sure to access fileserver B by setting
>   the fileserver preferences
> - my problem at this point is: the volume's root directory is empty
>
> Looking at the directory file at the fileserver's partition I see:

> fileserver A:

> ls -ln /vicepa/AFSIDat/j/jITQj=/+/+/=+++?2
