autofs direct mounts

Mark Ellzey — Mon, 20 Mar 2006 18:11:36 GMT

Hi,

Does anybody know how to do direct mounts on Linux? I'm finding very little information in the man pages and other supplementary documentation.

I'm trying to use NIS automount maps from a HP-UX 10.20 NIS master. The client is RHEL Ver 3.

I can get the indirect mounts to work fine, it's just the direct mounts I cannot find the information for.

Thanks,
Mark

Can you share your direct map configuration files?

Ivan,

I'm using NIS auto.direct maps from an HP NIS master. It looks like this:

/logs -rw,intr owl1:/vol/vol0/home/logs
/net_data -rw,intr \ owl1:/vol/vol0/home/net_data
/etest -rw,intr owl1:/vol/vol0/etest
/perl -rw,intr \ owl1:/vol/vol0/home/bin_tools/perl56

(owl1 is a Network Appliance)

Don't know if this will help, but any direction is appriciated.

Do you have nis configured in /etc/nsswitch.conf for the automount service?

automount nis files

Ivan,

Yep, that's just the way it looks in the nsswitch.conf file:

automount: nis files

Thanks,

Try changing the /etc/sysconfig/autofs file:

DISABLE_DIRECT=0

Mark,

Linux automounter doesn't support direct maps (at least, didn't support when I last timne checked it http://linux.about.com/od/commands/l/blcmdl5_autofs.htm)

Thanks for the input, fellas.

I suspected that maybe linux didn't support direct mounts. Nothing in the man pages for autofs, automount or auto.master point to direct mounts being possible. In fact, it looks like the only type of mount available is indirect.

Just thought I'd ask. I guess I can put the direct mounts in the fstab, though I would prefer not to.

Thanks again for your help.

Would using indirect mounts and
symlinking to the mounts work?

You could also enable /net mounts and
symlink to the appropriate directory.

Bill,

Yeah, that's my other idea.

Thanks,
