Hi, yesterday we attempted to update our AFS server encryption
keys. We have done this procedure a dozen or so times under
Transarc AFS with minimal problems. Yesterday was our first time
trying it under OpenAFS and things did not proceed as expected.

Based on some encouraging rumours, we are thinking about trying out
an AFS fileserver to serve very large volumes, 100gb+. Does anyone
who has tried this, or thought about it, have any feedback regarding:

2. size of partitions

Hi Jeff,
You should upgrade to 1.6 so you can increase -p to 255. This
will help but will not address the core problem.
I am working on that...I have a 1.6 server in test mode.
Do these processes communicate with each other to synchronize their work

Hi Jeff, thanks for your analysis and ideas on this issue.
On a similar notewe also experience random abuse on what we

Unless you manually set HAVE_POLL, you may not have it enabled in 1.6:
we didn't actually do the configure test for it. It will be fixed in 1.6.2.
Incidentally, of note, currently salvsync unlike fssync doesn't ever try
poll().
