Oh right, I remember that bug.<br>
I have, BTW, been enjoying the fruits of your AFS Windows endeavors.<br>
The VLDB entries were correct with "vos listvl root.afs/root.cell"
during this confusion -- but may have been in an inconsistent state at
some point.<br>
The only hypothesis I have right now involves clients having bad volume
location info, but why that wouldn't start for two hours escapes me.&nbsp; <br>
The client refresh of the cached volume info is on a 2 hr interval.&nbsp;
Surely some clients would have refreshed prior to the two hour mark at
which the issues began.<br>

I know of at least one that was active during the entire window of

I'm analyzing the file server detailed logs (not FileLog, the -auditlog
output) now and should be able to answer the question with some level of
confidence soon.

The reason I asked about the Windows clients is that there was a bug in
the Windows clients that prevented read-only fail over from working.  I
believe it was fixed prior to 1.4.0.  If your Windows clients were
working and the UNIX clients were not, that could point to a bug in the
UNIX clients.

If however the Windows clients are also failing, then it points to
something wrong in one of the databases.
