What version of OpenAFS is 'vos'? What version is the volserver?

What's happening here is that the volserver said "volume 536870936
doesn't exist", and when we tried to clone to volume 536870936, the
volserver said "you can't do that, because 536870936 already exists".
At least, that is what it means with newer versions, I'm not sure if
various older versions are in play.
So of course, that's a little confusing. Can you run on the 'primary':
# ls -l /vicepa/V0536870936.vol
# volinfo /vicepa 536870936
volinfo may be in /usr/afs/bin, if you can't find it. And can you look
in VolserLog and FileLog on "primary" to see if new messages appear when
you try to perform the release? Can you try salvaging the volume
536870926 on "primary", and provide what SalvageLog says? (or SalsrvLog
if you are running DAFS)

I don't think he was asking about an issue with it (unless there were
further emails involving an issue; I'm just skimming that), he was just
asking what the RClone field means / why it's there. So that explanaiton
is about the RClone field appearing, not about an error.

It certainly does exist in OpenAFS; if that option didn't exist, you'd
get an error that the option doesn't exist :) It just doesn't help with
this issue, because we are failing before -f/-force makes a difference.
