Question

Problem with mounting NIS automounts on solaris

Asked by: netezza

I have a RH server 5.3 as my NIS master. I have solaris 10 system as a client. The user auth works great on our linux and solaris systems but I can only get linux to use the automount.

Our solaris system can see the mounts but will not  mount them.
From solaris system
-bash-3.00$ ypcat -k auto.nfs
perfbar_results -defaults,hard,intr,nfsvers=3,tcp,rsize=32768,wsize=32768       rocky:/sqa-storage/sqa-export1/Netezza/felix/perfbar5_results
tizor-common -defaults,hard,intr,nfsvers=3,tcp,rsize=32768,wsize=32768  snap:/common
sw_serv1 -defaults,hard,intr,nfsvers=3,tcp,rsize=32768,wsize=32768      sw-serv1:/export
data1 -defaults,hard,intr,nfsvers=3,tcp,rsize=32768,wsize=32768 fram-data1:/export
-bash-3.00$ cd /nfs/data1
-bash: cd: /nfs/data1: No such file or directory
How can I get solaris to automount these maps?

Is the Solaris system either cknutson1247.netezza.com or qaweb.netezza.com? If not, that might be the problem. It would appear that the file system is not exported world readable and unless it is one of those two, it doesn't seem to be on the list.

I am not sure what the "/export *" is from, but on my system when the file system is world readable it shows as
"/export (everyone)"

Take a look at hte /var/adm/messages file for any error messages.

If there aren't any, you could try running snoop on the connection:

snoop -o /tmp/snoop.out -q kramer &
cd /nfs/production
pkill snoop

Then do

snoop -i /tmp/snoop.out -V

You can look at the protocol or post the output here.

 

by: netezzaPosted on 2009-09-02 at 13:23:21ID: 25245244

I ran this command and got no output.
bash-3.00# snoop -o /tmp/snoop.out -q kramer &

Does your system have more than one interface? Snoop will only capture packets from one interface at a time, and if the packets were using the other interface then it wouldn't have captured them.

Another thing you can do is try running the automount daemon as root, by hand with trace and verbose turned on.

To do that, first turn off the autofs service:

smfadm disable autofs

Then start up the automountd and automount commands:

/usr/lib/autofs/automountd -T -T -v
/usr/sbin/automount &

Then you can do cd /net/kramer and see what happens.

 

by: netezzaPosted on 2009-09-03 at 07:59:57ID: 25251361

That interface is the correct one. I ran the snoop again and ran showmount -e kramer. Snoop picked up communication between systems.

This looks like the map entry lookup failed. Looking back on your data, I think I see a problem. The format for the auto.master map is different on Linux and Solaris. There is no "source" designator in Solaris. In other words, Solaris expects to see "auto.nfs" in the auto.master map, not "yp:auto.nfs". Try removing the "+auto.master" from the auto_master file and restart the service. That way, the automount daemon will just pick up the /nfs entry from the auto_master file. If that works, you may either have to create a parallel map with the correct entries or just use the auto_master file.
