Hi folks.

I use OpenPli 2011-11-09 in my CT9100

I realize that every USB mass storage device (HDD or FlashDisk) inserted after E2 is up and running are mounted RW (ReadWrite).

So if I insert my USB HDD 500GB full of MKV videos, when I want to detach it I need to 'umount' it
How ? I've not find any simply E2 way to do it.
I need to connect to console and do a manual 'umount /dev/sd??' This is very annoying.

So yesterday I've made a simple E2 extension (I've called SimpleUmount) to provide a simple way to umount one device simple pressing remote control blue button and select SimpleUmount from extensions list.

There is a better way ?
I.e. force USB mass storage device inserted AFTER E2 is up and running to be mounted as RO (ReadOnly) ?
But mounted RO ONLY device inserted AFTER E2 is up.
I.e. I've an internal ext4 SATA HDD and and external 2GB ext2 usb flash drive always connected (I use this device to store some data as logs and CrossEPG data avoiding writing in main 128MB motherboard flash and avoding HDD wake-up): these devices are always connected and should be mounted always RW

I suspect that not skilled users know nothing about mount/umount procedures. They simply insert and remove device don't care about umount .... and probably they can have damage in device filesystem.


If you find useful SImpleUmount or want to test it, I can attach here.
And If you wish I can join E2OpenPlugin github community and add my simple plugin ....

Excellent idea, make it so!

If someone wish to test it ...

- Download the file attached here
- Put it in STB / directory
- cd /
- tar xvzf SimpleUmount.tgz
- restart Enigma2

Press on remote control the BLUE key and select SimpleUmount

Thanks for feedback.

Mmmhh ... I've tried to recreate the problem without success.
Dima73, a question for you:
- which image are you using ?
- which STB ?
- have installed an HDD or something else ?
- can you post the output of a 'mount' command, please ?

I've not understood.
If you are able to umount the USB drive, the plugin is working. WHEN it crash ?

[ambrosa]

Ok, found the bug :-)
Wait for correction.

The questions may not have to answer ?
I just seen them.

Yes and I'm happy about your feedback. Thanks
But remember that if anyone try to solve a bug, more details are appreciated
Often bugs are not in main code but in a strange user customization, so it's important that a developer know exactly how and when the problem occours.
This time the very_stupid_idiot_bug it's my own and I've solved it
Try new release and let me know.
Thanks again.

Version 0.2 ALL OK

Wait please.
I'm working in an improved version with some confirm messages, warning message if device cannot be umounted (because "busy") and auto reload device list.
When finally all will be fine, I will add multilanguage support in po/gettext fashion
