NFS problem with autofs

rilicek · May 14, 2019, 10:17pm

I can mount NFS via FSTAB without problems.

fstab:

10.0.0.2:/srv/net/dysk2/publiczny        /mnt/FSTAB/Publiczny   nfs    nfsvers=4.2                   0  0

But I have problem with autofs.

I have:
**auto.master
**

+auto.master
/mnt/serwer /etc/auto.misc --timeout 10

auto.misc

publiczny            10.0.0.2:/srv/net/dysk2/publiczny

I get:

ls -l /mnt/serwer/
razem 0

automount -f -v
100000000|Starting automounter version 5.1.5, master map auto.master
100000000|using kernel protocol version 5.04
mounted indirect on /mnt/serwer with timeout 10, freq 3 seconds
attempting to mount entry /mnt/serwer/.directory
key ".directory" not found in map source(s).
failed to mount /mnt/serwer/.directory

What am I doing wrong?

PS.
I haven’t problem with identical configuration in openSUSE 42.1.

What happens if you try:

ls /mnt/serwer/publiczny

Here, I don’t see anything in the mount point directory unless something is already mounted. But if I look explicitly at something that should be in that directory, that forces the mount.

I don’t know if the order makes any difference, but this is my auto.master

#
# Sample auto.master file
# This is a 'master' automounter map and it has the following format:
# mount-point [map-type[,format]:]map [options]
# For details of the format look at auto.master(5).
#
#/misc    /etc/auto.misc
/media/auto  /etc/auto.nfs   --timeout=60

#
# NOTE: mounts done from a hosts map will be mounted with the
#    "nosuid" and "nodev" options unless the "suid" and "dev"
#    options are explicitly given.
#
#/net    -hosts
#
# Include /etc/auto.master.d/*.autofs
# The included files must conform to the format of this file.
#
#+dir:/etc/auto.master.d
#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.
#
+auto.master

The +auto.master is the last entry.

Also, as nrickert indicates, the auto mount occurs on demand. the --timeout parameter is the umount delay when the folder is no longer in use.

@nrickert

It was so easy.

ls /mnt/serwer/publiczny

solved the problem.

Thanks for help.

See description of option “browse” in man autofs.master.

@arvidjaar

Thanks.

I added

DEFAULT_BROWSE_MODE = "yes"

down:

/ etc / sysconfig / autofs

and I’m testing this configuration.

Earlier I was creating symlinks and it was working too, and still works.

I am running Leap 15.1 on a new computer, autofs package 5.1.3-lp151.7.2
autofs misbehaving as discussed in this thread
I have two other Leap 15.1 machines, autofs (same package) working perfectly

Where does file /etc/sysconfig/autofs come from?
The file /etc/sysconfig/autofs on the new (misbehaving) machine is very different from the two working macines.
Is the file locally generated?

malcolmlewis · October 26, 2019, 2:13pm

Hi
No, it’s part of the original source, if you have made modifications it will not be over written if an updated package is installed as it’s set to noreplace. In the two working systems is there a autofs.conf.new file?

It actually gets put into a directory first (/var/adm/fillup-templates) then rpm macros install it.

cmcgrath5035 · October 26, 2019, 2:49pm

Thanks, Malcom.

No, my “working” 15.1 systems do not have a “autofs.conf.new” file, but they are both updated since at least Leap 14.x and perhaps much longer.
Maybe something got lost.

The new machine is a completely clean install of 15.1.

Just for the fun of it, I might try migrating the /etc/sysconfig/autofs to the new system to see if that works.

malcolmlewis · October 26, 2019, 3:35pm

Hi
Yes, that should work, I would check the differences first between the older file and the new.

cmcgrath5035 · October 26, 2019, 6:38pm

OK, I replaced /etc/sysconfig/autofs with an older version from a working 15.1 computer, restarted the autofs service and autofs now working as expected.
Here is the autofs loaded by my clean install (does not work)

And here is the /etc/sysconfig/autofs that works, copied from an evolved (serially updated via zypper dup) 15.1 machine
As you can see, big difference.

I have no idea how this appeared on my older system, autofs has worked for a long time.
I know I did not build it from scratch

As you can see, the Browse item is changed along with other parameters, per the Tumbleweed discussion above.

Thanks for your help, Malcom
