Removing USB memory
|
|
|
I'm running a GNOME desktop on a Debian Sid system.
I've noticed that if I right-click a USB memory stick icon on the
desktop and choose "Unmount Volume" the icon disappears immediately.
However the device may be busy in the background, and if I remove the
stick too early files copied to the stick may not "have arrived yet"
(the sync isn't done yet).
I've found two ways around it:
1. Unmount in a shell using `pumount'.
2. Keep a system monitor in the panel and have it show disk activity.
Is there any other way?
I'd kind of like a brief notification at the end informing me that the
device is fully unmounted.

I usually use KDE and I see that by unmounting a USB device from its
icon on the desktop, the icon seems to stay as long as the USB stick's
activity LED keeps blinking. For large files (images), I have noticed
that the icon stays on the desktop for quite a few seconds. Never had
corruption on the USB stick. So it appears KDE removes the icon of a USB
device only when the sync is complete. I am surprised Gnome doesn't do
so. BTW, I let udev mount the pluggable devices automatically. If you
are using fstab to do so, you can fix the mount options to set sync to
happen every time the USB device is accessed.

Not a very good answer!
If I'm in a terminal to issue a 'sync' command I might as well issue a
'pumount' command (which will trigger a sync as well). :-)

I let udev/hotplug/gnome-volume-manager do the mounting, that's a lot
easier then fstab.
Yes, it would be better if GNOME left the icon on the desktop until the
device is fully unmounted, however it doesn't :(

It does on my system. The icon will not be removed from the Gnome
destop until umount completes.
In other words, this is not a Gnome vs. KDE issue. It appears to be
a configuration issue.

This, however, may be the issue: your system may be misconfigured, or
this undesirable behaviour may be a result of the file system you
are using on your USB device.
So the question is: what file system do you have on the device that
disappears immediately when you umount it, and if applicable, what
are your fstab options for this device?
Finally, how do you have your system configured to automount hot
attached mass storage devices?

Sorry, the above sentence was supposed to be: "I am surprised OP's Gnome

I suppose the above sentences are aimed at the OP and not me. I have no
issues with the icons of automounted devices on my desktop (both KDE and
gnome).

If the behaviour *is* different (if pmount does properly wait for sync
to complete before it returns), then you almost certainly have a
configuration issue. If not, then you might be looking at either a
kernel/pmount mismatch issue, or more likely, a bug.

I'm quoting from my original email:
I've noticed that if I right-click a USB memory stick icon on the
desktop and choose "Unmount Volume" the icon disappears immediately.
However the device may be busy in the background, and if I remove the
stick too early files copied to the stick may not "have arrived yet"
(the sync isn't done yet).
So, there's no problem with pumount, it does its thing. The problem is
that there is no feedback to me, the user, of when it's done since the
icon disappears immediately.
| Quote: | Try logging out of any gnome sessions, then make doubly sure that no
gnome daemons are running, then switch to a virtual terminal, login,
and try pmount, write large file, pumount, and see what happens.
That gets any Gnome config out of the way.

As you see, GNOME _is_ the problem, getting it out of the way won't
solve anything :-)

I am surprised too :-)

I doubt udev is the party that mounts it. udev creates the device in
/dev, I don't think it can mount things.
AFAIU on GNOME this is what happens when a storage device is plugged in:
1. udev creates a device node in /dev
2. hal is informed about the new device
3. gnome-volume-manager gets informed by hal and calls pmount to mount
the device

Hmmm, what system is that?
Mine is a Debian Sid.
How do you unmount your device? In terminal or by right-clicking the
icon on the desktop?

Two partitions on the USB stick. One with vfat, one with ext2.
No entry in fstab, udev/hal/g-v-m/pmount does the mounting when I plug
in the device.

Yes, that is what happens. Nice explanation. I was being sloppy with my
one liner which was more or less meant to a 'slang' for the above steps.
My bad.
