OH?? I wish THIS had been announced. Particularly to those who had
previously registered problems about it with Transarc.

Here it is:

Mitch-
I'm attaching mail sent to Transarc directly from HP explaining the
relationship between AFS and HP-UX clusters. Let me know if you have
any questions.
Regards-
Kathy
*********************************************************************
From: Rose Palombo <[EMAIL PROTECTED]>
There's been some public discussion recently about AFS and HP-UX's
Diskless. Some sites have tried to run AFS on HP-UX diskless
workstations and have experienced kernel panics. This note is
just to clarify the relationship between DUX (our diskless protocol)
and AFS.
Since the filesystem looks exactly the same from every machine in a
DUX cluster, putting AFS anywhere in the cluster causes DUX to be involved.
In order to have this one filesystem view and file coherency, diskless
has hooks into the UFS and CDFS filesystems. The only filesystems that
can be used with diskless clusters are UFS, CDFS, and NFS. Therefore,
you cannot put AFS on a diskless cluster. It will not work.
In HP-UX 9.0, we have restricted third party filesystems, like AFS,
to standalone workstations via our new vfs_mount facility. At 9.0
customers will be restricted, by the kernel, from attempting to install
AFS on a diskless workstation. This will reduce to zero the number
of our customers who will attempt this and panic their system.
In case you're curious, the changes required to fully support
AFS on diskless are in both the kernel and AFS code. Kernel changes
are required to recognize AFS in diskless operations and changes to AFS
are needed to handle the additional diskless protocol operations.
It's also worth noting that the whole diskless landscape is planned to
change for HP-UX 10.0.

And futhermore, when I asked why it wasn't better known by Transarc
and publicized to AFS customers:

This issue has only come up twice. Once with a customer inquiring as to
whether or not it was supported and then your problem.
I've asked management to send email to all site contacts warning against
this.

But I don't recall ever seeing e-mail from Transarc management warning
about this problem. Your having never heard of it, given Kathy's
request of management, is interesting.
