Hi there,

I just wanted to share what I hacked up through some frustration. It's a script that will automatically mount usb devices that are attached.

It ties in to the hotplug architecture as closely as possible, without changing anything. So then I subscribed to this list to announce it.

Of course, that's when I discovered
http://users.actrix.co.nz/michael/usbmount.html by Michael Hamilton.

So I'll first give a rundown of differences:
My solution:
- only mounts the device that was just inserted (with some luck)
- is called automount_usb, so that, by changing the usb.usermap, it gets called every time a device is inserted and not just the first time
- creates remover scripts that have /bin/sh as the only dependency
- creates nicely readable names as mount points
- supports devices with multiple partitions
- is really small

But Michael's solution:
- makes KDE icons
- is easier to read

So, please have a look at the attached code, and tell me what you think about the device detection code. Michael, if you read this, we could perhaps merge the two efforts and get all the features.

Also, let's start a thread on making a gui.agent script that gets called by the hotplug scripts. It would notify the user of hotplug events. I feel that it should be called with the same environment as the other agents, with an extra HOTPLUG_PATH variable indicating the path on which the device is available, if applicable.

This could then be used by KDE, Gnome etc to notify the user.

Cheers,

Wout.

Hi,
Does anyone know whether this will work on the following situation:

1. The usb-storage device (ie USB card reader) is alreay plugged in the
system.

2. No CF/MS/SM/SD are plugged in yet.

Given the above assumption , Will the system automount the CF when the CF
card is plugged in ? Or We still need to manually enter " mount -t vfat /dev/sda1 /cf ".

I guess what I would like to see is to have something like CD's automount
when a CD is inserted.

Thanks

In reply to Wout Mertens

Hmmm,

Only one way to find out :)

The script is real easy to install, just copy it to /etc/hotplug, and run the line that registers it (you can find it inside the script).

I think the issue will be if the card reader sends usb plug/unplug events or not... if it doesn't, I really wouldn't know how to do it.

Actually, there's an easier way to test:
Plug in the reader, have hotplug enabled, and watch /var/log/messages to see what the kernel thinks is happening. If you see messages every time you plug/unplug a card, you're lucky, and it will probably work.

Good luck,

Wout.

In reply to Wout Mertens

The problem is you need a notification in the first place that a card has been inserted. Unfortunately, I don't think any card readers on the market provide this functionality. I've only been able to solve this with a kind of daemon that periodically tries to mount the card reader's filesystem and then pings it occasionally to make sure the card hasn't been removed. It's ugly and wasteful, but what other alternative is there?

That's it, I think Window's must have done the same thing you described. BTW, when you say "ping it to make sure card is not removed", do you mean that you try to mount it and check the status return from the mount?

Thanks for the feedback.

In reply to Wout Mertens

Maybe a possible check would be to try to read the first few sectors (partition table and boot record), and keep an md5 hash. If it changes, do the sensible thing... Could be faster and less resource intensive than trying to mount it.

That's it, I think Window's must have done the same thing you described. BTW, when you say "ping it to make sure card is not removed", do you mean that you try to mount it and check the status return from the mount?

Subject: Re: My first usb storage automount script :)
The problem is you need a notification in the first place that a card has been inserted. Unfortunately, I don't think any card readers on the market
provide this functionality. I've only been able to solve this with a kind of daemon that periodically tries to mount the card reader's filesystem and
then pings it occasionally to make sure the card hasn't been removed. It's
ugly and wasteful, but what other alternative is there?

Hmmm,
Only one way to find out :)
The script is real easy to install, just copy it to

the line that registers it (you can find it inside the script).
I think the issue will be if the card reader sends usb
plug/unplug events
Quoted 7 lines
or not... if it doesn't, I really wouldn't know how to do it.
Actually, there's an easier way to test:
Plug in the reader, have hotplug enabled, and watch /var/log/messages to see what the kernel thinks is happening. If you see messages every time you plug/unplug a card, you're lucky, and it will probably work.

Hi,
Does anyone know whether this will work on the following situation:
1. The usb-storage device (ie USB card reader) is alreay
plugged in the

2. No CF/MS/SM/SD are plugged in yet.
Given the above assumption , Will the system automount the

Hi there,

- is called automount_usb, so that, by changing the

- creates nicely readable names as mount points
- supports devices with multiple partitions
- is really small
But Michael's solution:
- makes KDE icons
- is easier to read

So, please have a look at the attached code, and tell me what you think about the device detection code. Michael, if you read this, we could perhaps merge the two efforts and get all the features.

This could then be used by KDE, Gnome etc to notify the user.

In reply to Wout Mertens

That's pretty much it. The logic is more or less:
On mass storage hotplug, try to mount FS.
If mount fails, start daemon which tries again every N seconds. If mount succeeds, start daemon which tries to read N sectors every N seconds.
If read fails, umount the FS and start waiting again.

Keeping a hash is a good idea to bulletproof the whole thing.
