We are using Red Hat 4.5 with autofs 4.1.3. We are in a mixed
Solaris/Linux environment. We have an automountMapName that needs to
support both NFS 3 and NFS4. To complicate things, the solution must
work on both Solaris and Linux. Here is what I have:
AUTO_MASTER:
dn: Automountkey=/-,automountMapName=auto_master,dc=foo,dc=bar
automountInformation: auto_direct
automountKey: /-
objectClass: top
objectClass: automount
dn: automountkey=/.hidden,automountMapName=auto_master,dc=foo,dc=bar
automountInformation: auto_hidden
automountKey: /.hidden
objectClass: top
objectClass: automount
Auto_hidden:
dn: automountkey=hiddenNfs4,automountMapName=auto_hidden,dc=foo,dc=bar
automountInformation: -fstype=nfs4 server:/
automountKey: hiddenNfs4
objectClass: top
objectClass: automount
dn: automountkey=*,automountMapName=auto_hidden,dc=foo,dc=bar
automountInformation: server2,server3,server4,server5:/vol/&
automountKey: hiddenMain
objectClass: top
objectClass: automount
From above in * of auto_hidden this must be nfs3 as that is all that is
supported by the servers in that automount. In the hiddenNfs4
automountkey this must be nfs4 as it has to cross a firewall.
The * is working perfectly. The problem is the hiddenNfs4 automount
map.
I can get it to work with Solaris with the following:
dn: automountkey=hiddenNfs4,automountMapName=auto_hidden,dc=foo,dc=bar
automountInformation: -vers=4 server:/
automountKey: hiddenNfs4
objectClass: top
objectClass: automount
Linux will work this this:
dn: automountkey=hiddenNfs4,automountMapName=auto_hidden,dc=foo,dc=bar
automountInformation: -fstype=nfs4 server:/
automountKey: hiddenNfs4
objectClass: top
objectClass: automount
Solaris will work with this, but fail for Linux
dn: automountkey=hiddenNfs4,automountMapName=auto_hidden,dc=foo,dc=bar
automountInformation: -fstype=nfs4,-vers=4 server:/
automountKey: hiddenNfs4
objectClass: top
objectClass: automount
Solaris will also work with this:
dn: automountkey=hiddenNfs4,automountMapName=auto_hidden,dc=foo,dc=bar
automountInformation: server:/
automountKey: hiddenNfs4
objectClass: top
objectClass: automount
Solaris looks like it tries nfs4 and then if that fails it will continue
to try 3, 2, etc....
What I need is either an automountmap entry that works with both or a
way to have Linux mirror Solaris in trying NFS4 first and not requiring
any options.
Can anyone please help me out on this. I have been stumped for a while
on this.
Thanks,
Daniel Lohin

Have you tried looking at a debug log of what's happening?
See http://people.redhat.com/jmoyer for information about setting debug
logging.

I don't know what's going on from this information but, depending on
mount(8), one or more of these should work.
Look at the debug log to find that out what is failing.
Linux mount(8) defaults to v3 ... so you can't make Linux work like
Solaris in this case.

BTW:
I would not recommend using NFSv4 with RHEL4 on a production system. It
is unstable and I have easily managed to crash the system while using
it. Go for RHEL5.
