We do almost exactly the same thing, except our auto.home map includes the
full path name, i.e.
prob-mp sonia:/h1/guest/prob-mp
rather than using the &. But I'm sure this is not your problem. I
explicitly specify the map type in /etc/auto.master, i.e.
/home yp:auto.home
but again, I doubt that has anything to do with your problem.
We're using autofs-4.1.3; what version are you using?
Since automounting works perfectly if it's a file map, I'm inclined to
blame YP and not look at either NFS mounting or autofs. (Do log files
suggest that I'm wrong here?)
Is it always the same users whose homedirs fail to mount? Or will Mangusa
mount one day and not the next? Do all the workstations behave equally? I
assume both servers have some failing users. Does the failure rate vary
with the time of day or with obvious system activities like backups? I
know that our YP wierds out at 2 AM when the backups kick off, because the
network is overloaded.
YP relies on UDP. If there were network problems that ate YP packets
intermittently, it would explain the problem. If a workstation pings the
YP server host (at a time of day when automount failures are seen), what's
the packet loss rate? Is there any other reason to suspect flakiness in
the YP server and/or client? Suppose you do "ypmatch $user auto.home",
iterating over and over through all your users, do you see any failures?
(We don't, except during backups.)
Good luck; I hope this helps.
