simple automount question

simple automount question

[chris barry]

I've googled, but have not found an answer to this seemingly simple
question.

I'm automounting /foo from box1 on box2. /foo has no files, just other
directories, one of which is bar.

box2 $ cd /foo
box2 $ ls
box2 $ (nothing shows up)
box2 $ cd bar
box2 $ cd ..
box2 $ ls
bar
box2 $


Q: how do I get all of the directories under /foo to show up after it's
automounted?

/etc/auto.master
/foo	/etc/auto.foo --timeout=60

/etc/auto.foo
(all on one line)
*              /
-fstype=nfs,rsize=32768,wsize=32768,tcp,rw,bg,hard,intr,noacl,nocto,async   10.20.30.40:/foo/&

Is my auto.foo wrong for this application?


Thanks,

Chris,
    if I understood your question right, you just want the folders to be 
fisible. If that's the case  you could try the -g (--ghost) option of 
automount.

cheers

No you're not.

You're mounting individual directories from box2.
Things like, /foo/bar, /foo/baz, etc, are mounted individually, as
requests to access them come in.

How would autofs know what these directories are, to create them, from
that map, * doesn't really say much and, even though this map has an ip
address in the location others may not?

I though '*' said everything ;)

So, the problem is auto.foo. I don't want it to make individual mounts
to every dir in /foo, I just want it to mount /foo when someone
accesses /foo/whatever. I'm assuming it should look like:

(all on one line)
/foo              /
-fstype=nfs,rsize=32768,wsize=32768,tcp,rw,bg,hard,intr,noacl,nocto,async   10.20.30.40:/foo/


I like the fact that /foo is disconnected automatically, so I don't want
to use fstab.

Read what I said again and ask yourself this question (again).
How does autofs know what these directories are, since it can only rely
on the map, not what may be inferred from the mount location (it could
include macros that aren't known till mount time!

What are you trying to say?
Describe what you are asking and include the version of autofs.

If you are saying that 10.20.30.40:/foo is an export that you want to
mount on a single level directory path, /foo in this case, then you will
need to use a direct mount and version 5 of autofs. This won't work in
version 4 and never will.

For example, in the master map
/-	/etc/auto.direct

and in auto.direct
/foo	10.20.30.40:/foo

will do this.

Ian,

That was the answer I was looking for.

Thank You,
