Autofs picking first server from the automounter map all the time

Autofs picking first server from the automounter map all the time

[Patel, Rahulkumar [NJ]]

Hi,
I have following entry defined in the automounter map.
But, when I try to access it all the time it pick last server defined for
that mount.

perl -ro,soft,nosuid,noquota,intr server1:/vol/vol1/software/perl
server2:/vol/vol1/software/perl.


When I cd /home/perl --> All the time I connect to server2.

I am running autofs-3.1.7-21.

Does anyone has idea why this is happening ?

Thanks
Rahul

Autofs 3.x and autofs 4.0.x didn't have real support for replicated 
server.  It simply picks the first server in the list.

Autofs 4.1.x does include support for replicated server.  You should 
upgrade and test.

I'm not sure if this should work in v3.

It should work in 4.1.1 and above but it seems that I have broken that 
behaviour when I merged the patch for it. I'll have to fix it.

However an entry like:

perl -ro,... server1,server2:/vol/vol1/software/perl

works as expected.

This specific feature didn't work. I must have broken it when I merged the 
patch.

I've been working on it much of the weekend and it's fixed.

As a side benefit I think I discovered one cause of those nasty "BUG: dir 
already mounted" messages which cause things to go pear shaped.

I'm going to post an appeal for help testing it in a minute.

I will help test if you could point the location of the patches.
