Hi abishai ,

I've never seen this problem before. I don't want to hijack the thread, but what version of dsbmd are you using? Maybe there is an unresponsive device which is polled by dsbmd. If you're using dsbmd >= 0.3, you can disable polling by setting poll_interval = 0 in /usr/local/etc/dsbmd.conf, and see if the problem persists.

I use latest version available in ports, to it is > 0.4 I suspect the problem is gvfs node for compatibility with posix applications.
Code: 
/dev/fuse on /home/abishai/.gvfs (fusefs, local, nosuid, synchronous, mounted by abishai)
I think, ~/.gvfs enumeration should be disabled in dsbmd. gvfs tries to mount this folder if user has necessary rights (write access to /dev/fuse and vfs.usermount).
 
when i plug a usb stick with ntfs file system ,i cant open it in KDE4(dolphin file manager) ,i get the error :
image.jpg

(have already done the above instructions) the only way to mount it manual is with the command :
Code: 
ntfs-3g /dev/da0s1 /mnt/flash
still cant see it in file manager but i can see files in /mnt/flash
any way to fix this(skip executing the command) ?

my rc.conf :
Code: 
sshd_enable="YES"
# Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable
dumpdev="NO"
dbus_enable="YES"
hald_enable="YES"
kdm4_enable="YES"
ipv6_network_interfaces="none"
ipv6_activate_all_interfaces="NO"
ip6addrctl_policy="ipv4_prefer"
ip6addrctl_enable="NO"
autofs_enable="YES"
portmap_enable=YES
portmap_flags="-h 127.0.0.1"
amd_enable=YES
amd_flags="-a /.amd_mnt -c 10 -w 2 -l syslog /host /etc/amd.map"
fusefs_enable="YES"

have tryed as well with
Code: 
#hald_enable="YES"
should i make it
Code: 
hald_enable="NO"
?

ntfs is not supported. So it seems it is not possible to mount it with autofs, as far as I know (I've never tried.).
Only fat32 and devices with mtp support. So just use fat32 on your flash drives for compatibility with FreeBSD and Windows machines.

thank you both for your comments ,i have to figure how trueOS has done it,their automount works fine with fat32 and ntfs
 
Checked /etc/autofs/special_media and found that ext2fs(5) also seems to be supported
(ext2fs.ko kernel module should be loaded). As well as "exfat" (but sysutils/fusefs-exfat should be installed).
Didn't find out it before, because I don't use Windows or GNU/Linux anywhere. Added to the first post in this topic.

Yes, for me, it works out of the box; my external memory storage has never failed to be mounted :), and my secondary hard drive, with a NFTS partition, is correctly automounted as well
 
found that ext2fs_load="YES" , causes my fat32 usb sticks not working with autofs

automounting works ,everything is mounted in the /media/daXXsXX
but i cant write on ntfs.

fusefs-ntfs is installed
fuse.ko is loaded
Code: 
$ kldstat
Id Refs Address            Size     Name
 1   63 0xffffffff80200000 1f67a88  kernel
 2    1 0xffffffff82169000 4d18     coretemp.ko
 3    1 0xffffffff8216e000 1a8c8    fuse.ko

any ideas?

OK, forgive my problem that is opposite to everyone else's o_O I would like to NOT mount the ntfs volumes in my workstation because I dual-boot with windows and have no need to have these disks mounted while I am in FreeBSD. I have read the man page on auto_master() but am probably doing this wrong. Is there a configuration that prevents automounting of certain disks? It appears the "-null" parameter or flag I read about in the auto_master() documentation can do this but it is not clear how. I don't have an issue with mounting these drives but boot takes forever because it appears the drives are being checked for consistency and I do not need this to happen.

Thanks in advance.
 
I thought of that, good old occam's razor :). I didn't do it because automount is a dependency but maybe I am confusing autofs and automount. 2 separate things?

Thanks Iluxa.
 
For me autofs does not work at all. I do

#service hald stop
#service automount onestart
#service automountd onestart
#service autounmountd onestart
#cd /media
#ls

and this is what I get:

Code: 
WARNING: autofs_trigger_one: request for /media/ completed with error 5
WARNING: autofs_trigger_one: request for /media/ completed with error 5
WARNING: autofs_trigger_one: request for /media/ completed with error 5
WARNING: autofs_trigger_one: request for /media/ completed with error 5
WARNING: autofs_trigger_one: request for /media/ completed with error 5

When I plug in an USB-Stick nothing happens, output looks like this:

Code: 
$ mount
/dev/ada0p2 on / (ufs, local, soft-updates)
devfs on /dev (devfs, local, multilabel)
/dev/ada1p2 on /Disk2 (ufs, local, soft-updates)
fdescfs on /dev/fd (fdescfs)
procfs on /proc (procfs, local)
linprocfs on /compat/linux/proc (linprocfs, local)
tmpfs on /tmp (tmpfs, local)
map -media on /media (autofs)
/dev/fuse on /usr/home/werner/.gvfs (fusefs, local, nosuid, synchronous, mounted by werner)

My /etc/auto_master looks like this:

Code: 
$ more /etc/auto_master
# $FreeBSD: releng/11.1/etc/auto_master 310007 2016-12-13 04:44:06Z dteske $
#
# Automounter master map, see auto_master(5) for details.
#
#/net           -hosts          -nobrowse,nosuid,intr
# When using the -media special map, make sure to edit devd.conf(5)
# to move the call to "automount -c" out of the comments section.
/media          -media          -nosuid
#/media -fstype=cd9660 :/dev/cd0
#/-             -noauto

I would like to automount optical media, too, so would the outcommented line be OK?

All you need to do, to make it work:
1. Uncomment media line in /etc/auto_master.
2. Add autofs_enable="YES" to /etc/rc.conf.
3. Reboot.

Also it is possible to add sysutils/fusefs-simple-mtpfs support to autofs, check this.
 
The media line was already uncommented, please have another look at my original post. I also tried adding some options like suggested in the other thread to make it look like this:

Code: 
$ more /etc/auto_master
# $FreeBSD: releng/11.1/etc/auto_master 310007 2016-12-13 04:44:06Z dteske $
#
# Automounter master map, see auto_master(5) for details.
#
#/net           -hosts          -nobrowse,nosuid,intr
# When using the -media special map, make sure to edit devd.conf(5)
# to move the call to "automount -c" out of the comments section.
/media     -media    -nosuid,-m=770,-L=en_US.UTF-8
#/media -fstype=cd9660 :/dev/cd0
#/-             -noauto
$

Please note that the media line is uncommented, just as above. I also added autofs_enable="YES" in my /etc/rc.conf and set hald_enable="NO", and rebooted, but this is just the same as starting the services manually. In console mode (without starting X) I also realized the following message in addition to the one originally stated above:

failed to handle special map "-media".
 
For me it works as described above,
so I don't know why it's not working for you...
Just a guess, is /media directory exist in your system?
after adding all settings, your mount output should be similar:
sGm8TNs.png


You don't need to launch something manually after adding autofs_enable="YES" to /etc/rc.conf.

Of course it does, without it HAL would not work either. I do get the same output as you when I do a $mount. But what I am saying is that when I plug in a USB-Stick or a CD, nothing happens. They should be listed in &mount, too, right? And they should appear in the media directory also, but they don't. When I do a &ls /media nothing is in there.

I can only tell you this: My system has always been updated with freebsd-update since the first fresh installation years ago with 9.0 or even 8.x, I don't remember now. But that should not be a problem, I hope. My output is:

Code: 
$ uname -a
FreeBSD amd64.my.domain 11.1-RELEASE-p4 FreeBSD 11.1-RELEASE-p4 #0: Tue Nov 14 06:12:40 UTC 2017     root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64
 
Try this, it may help, may be you got device permissions problems.
This is what I use, create /etc/devfs.rules with
Code: 
[system=10]
[b]add path 'da*'          mode 0660[/b]
add path 'mmcsd*'       mode 0660
add path 'pass*'        mode 0660
add path 'xpt*'         mode 0660
add path 'ugen*'        mode 0660
add path 'usbctl'       mode 0660
add path 'usb/*'        mode 0660
add path 'fd/*'         mode 0660
inside

And add
Code: 
devfs_system_ruleset="system"
to /etc/rc.conf.

("add path 'da*' mode 0660" is your USB flash drives permissions)

Your user should be in operator and wheel group.
Execute
# pw groupmod wheel -m yourusername
and
# pw groupmod operator -m yourusername

Then relogin and execute # service devfs restart.

ILUXA actually adding add path 'da*s*' ( add path 'da*p*' for flash drives containing a BSD slice) sort many issues out in my case, whereas bare 'da*' had failed granting me write permissions on automounted devices.


All things considered I have to say I'm satisfied with autofs. With FUSE I automount mount EXT4 -ro, exFAT USB stick and NTFS external drive -rw without issue. I can also mount HFS using sysutils/hfsutils, when I boot in someone's Mac through a USB stick. Only my XFS Linux-home partition l ends up being umountable on desktop, but really, no harm done.


However, despite having thoroughly looked auto_master(5) over, I still don't know whether I managed to understand or not how it works for real (mountpoints, direct/indirect/special maps). For example, does specifying a custom mountpoint in /etc/auto_master require a custom map? I specified -media as special map since it seemed the most obvious choice, but then apparently no change was applied and /media remained always as automount point even when the corresponding entry in auto_master was commented.

I ended up giving ownership for /media to my standard user and creating a simlink on desktop pointing to it.

It a long time now (years), I'm doing this that way, and I'm fine as lonh as it works, but I was looking for a more proper solution...do if anyone is so kind to enlight me on that I would definitely appreciate it :)

There is no need to add 'da*s*', it should work OK with 'da*' with all USB flash drives.

Well then, guess it was some wrong permission set the first time I tried. It was a long ago, and I was a beginner, I've never tried to see whether simple da* would have worked ir not from that moment on.
By the way, have you ever tried setting a custom mount point, preferably inside /usr/home/user?
