If I have a file server/vol server that I have signaled with -STOP (i.e. suspend them
so that they will still be listening on port, but not doing anything with received
packets), and then issue an afs call on a client against a volume on the server - it
hangs.
That's expected.
What controls how long the client sits there before generating the "Connection timed
out" message?
Is that mechanism different for a readonly volume located on that server?
-------
The reason I ask - I was finally able to reproduce a symptom we have seen MANY times
when we've had problems with a server that would cause the clients to be unusable.
Note - this isn't a reproduction of the problem with the server, but something I can
do on the server that reproduces the symptom we've seen.
Add vol1 on srv1
Create some large files on the volume
Replicate to srv1 and srv2
Set server prefs on client to prefer srv1 (not sure this is necessary)
Access the volume, but don't touch one of the files, cd into it and ls or
something
Kill -STOP both the fileserver and volserver on srv1.
Now, attempt to access one of the files you haven't accessed. (I did a tail on
a 500MB file.)
It was almost 10 minutes before the client station gave up and switched to srv2.
Needless to say, in an environment that makes heavy use of afs, if that volume was
root.cell, it would have caused a significant problem (in some cases, would have
brough to their knees) any client that was pointed at that server.
In the case of a read-write volume doing the same set of steps, it took about 30-45
seconds before it switched.
If there is another read-only server, I would like it to switch after 10-15 seconds at
most. Maybe there is some reason that's a bad idea, if so, I'd like to discuss it.
BTW, This was on a linux client running -current on 2.4.18pre7, file+vol server srv1
same kernel and afs, and file+vol server srv2 running an older (around June 2001)
file+vol server on solaris.
