Hey, thanks for all this!
No worries. Thanks for the feedback.
I created a thumb drive for testing. Using the actual drive takes too long,
as the cable is awkward, the drive spins up and down, etc.
I added my uid/gid to the rule for jollies, so it mounts as me instead of
root.
I'm uncertain of the advantage if you are a member of user. You can
use the USER tag in the rule to run commands as someone other than
root.
Plex should work in either case with wide-open 777 mode.
Agreed
ACTION==add, PROGRAM==/sbin/blkid -o value -s TYPE /dev/%k,
RESULT==ntfs,
ENV{mount_options}=%E{mount_options},utf8,uid=1000,gid=1000,umask=000
Oddly uid=N and gid=N in the ntfs-3g man (rather than uid= and
gid=) I'm not sure if that's why mount | grep $SomeNTFSSlice
reports single digit uid and gid [puzzled]
There was a problem in the dir_name,
Could you expand on that?
so I changed these two lines:
#ACTION==add, PROGRAM==/sbin/blkid -o value -s TYPE %E{device},
RESULT==ntfs,
ENV{mount_options}=%E{mount_options},utf8,gid=100,umask=002
ACTION==add, PROGRAM==/sbin/blkid -o value -s TYPE /dev/%k,
RESULT==ntfs,
ENV{mount_options}=%E{mount_options},utf8,gid=100,umask=002
What do you get from mount -L | grep Win?
# Get label if present, otherwise assign one
#PROGRAM==/sbin/blkid -o value -s LABEL %E{device}, ENV{dir_name}=%c
PROGRAM==/sbin/blkid -o value -s LABEL /dev/%k, ENV{dir_name}=%c
When I unmount the drive, the directory is not deleted. The
owner/permissions change from me/777 to root/755. I see you have commands
for umount and rmdir (Clean up after removal), but I'm not sure what is
meant to kick those off.
That /media/$NFTSSliceLABEL dir will remain. That the notoriously
fickle NTFS 'might' be damaged if the mounted NTFS device is suddenly
removed (more likely you might just get into a futile tug-of-war).
Belt and suspenders?
I pulled out the drive without umounting first, not
that I think you had that in mind, but that didn't change the behaviour
(much).
Did a program have access to that file system at the time?
It seems that only root can umount the drive, but I've seen mention of that
for NTFS, or maybe it was udisks in general?
NTFS-3G. After digging through policy kit it 'seems' if a non-root
user who is not a member of the disk group wants to umount NTFS they
need to recompile ntfs-3g with build-in FUSE and then setuid the
resulting binary.
Almost there!
Lots of room for improvement - if I had time I'd refine the rule to
*only* apply to a unique NTFS slice, and figure out a way so that the
slice icon that appears on XFCE desktop and in the sidebar of Thunar
*is* the mounted NTFS slice.
An alternative approach to solving the above two niggles would be to
hide the dysfunctional icons, and automagically (using udev) add an
icon to the desktop - which when clicked would umount the (WinBackup)
slice (gksudo or similar - if you use sudo that wouldn't be
necessary).

Rick

Sorry for replying to my own post...
I see now that it's the XFCE's volume management that is initiating the
(hotplug) mount. Some digging found that udisks is involved, so I
attached strace to the udisks-daemon and found this:
[pid 29472] 10:58:32 execve(/sbin/mount.ntfs, [/sbin/mount.ntfs,
/dev/sdg2, /media/WinBackup_, -o,
rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,dmask=0077,fmask=0177],
[/* 3 vars */]) = 0
So the mode that I'd like to change is coming from the udisks-daemon (or
its parent). Strace on udevd shows that it's involved but I don't see
any file modes.
That's were I'm at now. I played with udev rules a bit but I've never
worked with them before.
Quick comment (I will get back to this later today or early tomorrow):-
grep ntfs /lib/udev/rules.d/*.rules
/lib/udev/rules.d/80-udisks.rules:ENV{ID_FS_TYPE}==ntfs|vfat, \
If this does control the effect you note, (which is easy to determine),
then it's simple to create a rule based on it
(/etc/udev.d/$something.rule) that will treat your WinBackup disk
differently
I grabbed the src for udisks, but didn't get very far. It has code that
checks fstab and uses its entries if found, but that code isn't used. It
always makes a call to udev_glib instead.

Rick

The default settings for external drives is in /lib, offhand I can't
remember where filetypes is taken from (somewhere in /etc ?). Take a
look at udisks-doc if you're interested. Most of udisks, as you've
discovered, is binary.
Another very quick comment as I haven't had a chance to do much Debian
User stuff lately (will get back to this and an Apple udev rule this
evening).
The udisk rule I pointed out above - is fine as it is, it hides
disk/slices that would normally need to be hidden.
I need to finish testing a custom udisks rule for you that changes the
default naming of new devices that have an ntfs file system to
/dev/$Label and a udev rule that runs fuser to automount the drive (to
/media/$Label. It can be done with just udev, but it's a crude hack
(doesn't cleanly umount, creates incrementing /media/usbN). Then you
should get the Thunar support you want for Plex.

Rick

It mounts when I plug the drive in to the running system, just not with the permissions that I need. I hope I didn't lead anyone to think I'm asking about a boot-time mount issue. Over the years the hot-plug system (if that's the name for it) seems to have changed a few times, and I admit I've never understood how hal, udev, etc worked/works. It's always worked to some extent, so I've never had to fuss with it. ntfs-3g's umask/dmask/fmask options all default to 0, but somebody is calling it with dmask=0077,fmask=0177. I haven't figured out the chain of commands involved. The ntfs-3g ref I (believe I) posted earlier on the thread is instructive (it's to upstream documentation).

I see now that it's the XFCE's volume management that is initiating the
(hotplug) mount. Some digging found that udisks is involved, so I
attached strace to the udisks-daemon and found this:
[pid 29472] 10:58:32 execve(/sbin/mount.ntfs, [/sbin/mount.ntfs,
/dev/sdg2, /media/WinBackup_, -o,
rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,dmask=0077,fmask=0177],
[/* 3 vars */]) = 0
So the mode that I'd like to change is coming from the udisks-daemon (or
its parent). Strace on udevd shows that it's involved but I don't see
any file modes.
That's were I'm at now. I played with udev rules a bit but I've never
worked with them before.
Quick comment (I will get back to this later today or early tomorrow):-
grep ntfs /lib/udev/rules.d/*.rules
/lib/udev/rules.d/80-udisks.rules:ENV{ID_FS_TYPE}==ntfs|vfat, \
If this does control the effect you note, (which is easy to determine),
then it's simple to create a rule based on it
(/etc/udev.d/$something.rule) that will treat your WinBackup disk
differently
Later.

I saw that rule last night, but it is in the section Partitions which

How to override fuse args to ntfs-3g to set permissions?
Well, many hours of googling, and running grep on my entire filesystem, have failed me this time. I'm running up-to-date wheezy.

Why not uid=$username,gid=users All the options were copied from the mount options in the syslog above. I removed the ones that mount didn't like (blkdev and fsname). I wanted to start with what (I think) fuse is giving ntfs-3g on it's command line (not that that's a valid thing to do). fuse doesn't seem to be a binary executable, and I can't find where these command line args are coming from when mount is called. Do you want to retain and use standard Windows permissions? How many people will need access to the disk? Nobody else uses the machine, but I need the permissions opened up. When my WinXP server died I moved my videos to my Linux desktop. I usually use Serviio but thought I'd give Plex a try (Plex doesn't support XP so I couldn't give it a try until now). Plex runs as user plex and cannot read any of the files on this USB disk when mounted under my account with mode 600 permissions. Plex has an option to let the client delete videos, so while testing I chose . I could tell Plex to run as me, but that's no good because its files are installed under /var/lib/plexmediaserver, and if I change the ownership of those it would likely break upgrading Plex when the next deb file is released.

No. You need to uncomment line 9 in /etc/fuse.conf so that allow_user will work in your fstab (from not-to-be relied on memory - it still won't allow a non-root user to umount the device).
