Is there any intellectual property being created? If so is it being
protected?
It appears that the proposed improvements are superior to Microsoft's
filesystems.

looking at src/volser/dumpstuff.c, it appears that dumps are done in
ascending vnode order. AFAIK, rename is a first-class operation so it
should only dirty the source and dest dirs.

Subject: [OpenAFS] Volume creation tool
I was searching for something else recently, and happened across
a web page mentioning a tool or utility which creates an AFS
volume on one of several partitions, choosing the one best
suited according to some configurable criteria. Unfortunately
I didn't keep the URL, and I can't find the thing despite some
searching. Does anyone know what this may be and where it may
be documented or obtained? I thought Stanford was mentioned in
the original page, but I can no longer be certain.

You're probably looking for my volcreate utility, which is at:

Hello Jim
here is another stack trace. It is from the salvager:

This salvager problem hits me most because no salvager version works on the
OpenAFS server and I have about 150 GB of data on it including important web
pages. One further information: the fileserver is a namei server and the
vicepcp partition is an JFS2 filesystem.
Thanks for any assistance
Gunther
