making the mountpoints visible all the time

making the mountpoints visible all the time

[Alexander Macdonald]

Hi

I've currently got automount setup so that i can cd into a directory 
like /mnt/someplace and someplace will be automatically created and 
mounted... it would be quite usefull if that directory was allways 
visible so that i could browse to it in gui applications... how do i do 
that?

If you want it visible all the time, use /etc/fstab, not autofs.  Work 
is being done on leaving the directory structure before actually 
mounting it, but it is not finished yet.

Or you can fake it by having a directory where autofs puts its stuff and in the
directory where you want the mounts, have softlinks back to the correct autofs
location.

like autofs puts its stuff in 
/.autofs/mount1
and you do
ln -s /.autofs/mount1 /mnt/mount1

there are 2 problems I have seen with this (though I still use it)

1) if your home directory is in /mnt/mount1 you (if PS1=\h:\w\$ on bash) will
see "machine:/.autofs/mount1$ " until you type cd once.

2) if you do an ls in /mnt/ (or navigate a netscape/openoffice.org [save/open]
through it) you will be waiting until autofs has processed mounting all the
autofs mounts.

Umm ...

Beg to disagree.

The autofs4-2.4 module build kit or the patches contained in it or the
patches contained in autofs-4.1.0-beta3 can give you this for some of the
maps. NIS, LDAP and file maps work at the moment.

I's in the expected place on kernel.org.

not sure what you mean by file maps, but I'm trying to mount samba and 
nfs shares so i guess I'm out of luck...

In order to view the mountpoints before they are mounted you need
to have the newer version of the kernel module which is available
at kernel.org.

The maps aren't really specific to the type of filesystem you are
trying to mount.  You can get your maps from a local file, NIS, LDAP,
etc.  They can contain information to mount smb, nfs, or even local
filesystems.

If you install the newer kernel module, you can make your mountpoints
visisible with the ghosting option.  One way to enable this is to 
set it in your /etc/auto.master like:

/somedir	file:/etc/auto.somedir	-g

Or you can add the "-g" to the "daemonoptions" variable line in 
/etc/init.d/autofs.

Maps are where you get your mount information from. You could be using any
map and mounting a kind of share (nfs/smbfs).

If you use local files for specifying which server/share to mount, then
you are using file maps.

If you look in the samples directory, a file map is the auto.misc map.

        Hello, Ian and other.
As I've understand you've implemented readdir relaited syscalls in 
autofs for some map types, have you?

If so then I hope that soon we could see programm maps with such 
functionality.
I want to do progamm map wich allow something more native representation 
of windows workgroups like NetworkNigborhood. It would be very useful in 
plain networks(like our ~900 PC in one workgroup).

            Best regards. Ruslan.

Re: making the mountpoints visible all the time

[Alexander Macdonald]

I'm using kernel 2.6.0-test9, i could only see patches for 2.4 so i 
guess this has the latest autofs in it allready right? I've also 
upgraded my daemon to autofs-4.1.0-beta3. I then tried running this:-

automount -g /mnt/network/samba/computerA file /etc/autofs/samba

in the file /etc/autofs/samba I have this:-

download    -fstype=smbfs,username=guest,password=none ://computera/Download
upload        -fstype=smbfs,username=guest,rw,password=none 
://computera/Upload

it works fine but it still doesnt do the "ghosting"

I haven't tried the 2.6 kernel yet, so anything I suggest would be
based on experience with the 2.4 kernel.

One thing is to make sure you have an entry in /etc/modules.conf
to force loading of the autofs4 module.

It should look like:
alias autofs autofs4

If you have to add the line then stop autofs.  Do "rmmod autofs"
and then start autofs again (I believe the init script will load
the module for you).

Basically, yes.

Some other related changes were also needed to make direct mount handling 
in the daemon simpiler (when working with the updated module).

But how do you know what the keys are?

In order to make mount points visible you need to know what they are. The 
definition of a program map is that it produces map entries as output 
given an input key.

You need a new operation on a map -- enumerate.  Most, but not all map 
types support it.

In the case of a program map I would suggest implementing enumeration by 
passing no argument and expecting the enumerated list back.

I've had some trouble lately with using the -g.
If this is a problem use the long option --ghost, that seemed to work OK.

Now it is my turn to apologize.  I saw the autofs module on the ftp
site, but I didn't have time to investigate.  Has this module been
included in the upstream kernel yet?

No.

I have mailed Marcello Tosatti asking what I need to do for my changes to
be included but he hasn't sent any reply.

On the upside, when I commplained about not getting my changes into the
kernel the other day and copied it to the LKML, Peter Anvin suggested I
submit my patches for inclusion in 2.6. He sounded quite positive and I'm
currently porting the changes. You may have seen the recent discussion.
