Description Derrien 2006-07-17 16:03:24 UTC
Description of problem:

The system doesn't wait the mounting of NFS file system defined by a NIS map

Version-Release number of selected component (if applicable):

[root@d380 (FedoraCore 5) ~]$ rpm -q  autofs
autofs-4.1.4-29

(NB same pb with autofs-4.1.4-16.2.2)

[root@d380 (FedoraCore 5) ~]$ uname -a      
Linux d380.irisa.fr 2.6.17-1.2145_FC5smp #1 SMP Sat Jul 1 13:19:14 EDT 2006 i686
i686 i386 GNU/Linux

Additional info:

[root@d380 (FedoraCore 5) ~]$ cat /etc/auto.master
/-      yp:auto.net --debug
/udd    yp:auto.udd

[root@d380 (FedoraCore 5) ~]$ ypcat -k auto.net
/net/usr/local -ro,hard nas1b:/vol/ren1b_soft_unix/local/${ARCH}_linux
/net/usr/share -ro,hard nas1b:/vol/ren1b_soft_unix/local/share
/net/src -rw,nosuid,soft nas1b:/vol/ren1b_soft_unix/src

User ltest needs /net/usr/local to connect on d380 (his login shell is
/net/usr/local/bin/tcsh) :

mac 37 % rlogin -l ltest d380                  
Password: 
Last login: Mon Jul 17 16:28:36 from mac.irisa.fr
login: no shell: No such file or directory.      <== don't work
Connection closed.
mac 38 % rlogin -l ltest d380                    <== immediately after it work
Password: 
Last login: Mon Jul 17 16:35:40 from mac
exec cshrc generique
exec login generique

The log :

Jul 17 16:43:47 d380 automount[2247]: attempting to mount entry /net/usr
Jul 17 16:43:47 d380 automount[4285]: starting automounter version 4.1.4-29,
path = /net/usr, maptype = yp, mapname = auto.net
Jul 17 16:43:47 d380 automount[4285]: using kernel protocol version 4.00
Jul 17 16:43:47 d380 automount[4285]: using timeout 60 seconds; freq 15 secs
Jul 17 16:43:47 d380 automount[2247]: attempting to mount entry /net/usr/local

NB: If I make a file (ypcat -k auto.net > /tmp/auto.net)
and modify /etc/auto.master (/-      file:/tmp/auto.net --debug) 
it works like expected.

Please provide the debug logs for the automounter.  I have detailed instructions
on how to obtain these logs on my people page:
  http://people.redhat.com/jmoyer/

Thanks!

Jul 24 19:07:35 d380 automount[2311]: starting automounter version 4.1.4-29,
path = /net, maptype = yp, mapname = auto.net

...

Jul 24 19:07:40 d380 automount[2311]: handle_packet: type = 0 
Jul 24 19:07:40 d380 automount[2311]: handle_packet_missing: token 1, name usr 
Jul 24 19:07:40 d380 automount[2311]: attempting to mount entry /net/usr

Up to this point, we're doing just fine.  But then:

Jul 24 19:07:40 d380 automount[2311]: handle_packet: type = 0 
Jul 24 19:07:40 d380 automount[2311]: handle_packet_missing: token 2, name
usr/local 
Jul 24 19:07:40 d380 automount[2311]: send_ready: token=2 

Uh oh!  The submount process was supposed to get the lookup of "local". 
Interesting that we simply decide that it was successful and return.  And then,
the event gets propagated to the right process:

Jul 24 19:07:41 d380 automount[2346]: handle_packet: type = 0 
Jul 24 19:07:41 d380 automount[2346]: handle_packet_missing: token 3, name local 
Jul 24 19:07:41 d380 automount[2346]: attempting to mount entry /net/usr/local

I'm not sure why moving this to a file-map would make any difference, though. 
This looks like a kernel issue.
