Auto mount USB drive from .X.d Not Working

[pek]

Hi All,
I need another help again today

My aim:
1. To auto mount a USB drive with specific label name after X started.
2. run a script from from the USB.


What I did:
1. create a script to mount the USB /home/tc/mountUSB.sh

Code: [Select]

sudo mkdir /tmp/theUSB
sudo mount -L theLABEL /tmp/theUSB
sh /tmp/theUSB/theSCRIPT.sh
2. create a file to load it in /home/tc/.X.d/loadit

Code: [Select]

exec /home/tc/mountUSB.sh &

The problem:
**After boots up to X, the USB was not mounted.
But the /tmp/theUSB directory was successfully created.

**If I manually type exec "/home/tc/mountUSB.sh" in aterm, everything works perfectly and the script within the USB was launched successfully.

Can anyone help me on this please?
Thank you.

Hi pek
Try it like this:

Code: [Select]

#!/bin/sh

Code: [Select]

sudo mkdir /tmp/theUSB

Code: [Select]

drive="`/sbin/blkid -lt LABEL=theLABEL -o device`"

Code: [Select]

sudo mount "$drive" /tmp/theUSB

Code: [Select]

/tmp/theUSB/theSCRIPT.sh
Make  /home/tc/.X.d/loadit  look like this:

Code: [Select]

/home/tc/mountUSB.sh &

Hi Rich, thanks for your suggestion.
However it behaves exactly the same like the original.

**After boots up to X, the USB was not mounted.
But the /tmp/theUSB directory was successfully created.

**when I type exec ./.X.d/loadit in aterm, everything works perfectly and the script within the USB was launched successfully.

Hi pek
Try adding a  sync  command after the  mkdir  line.
Also, make sure your script is executable:

Code: [Select]

chmod 775 /home/tc/mountUSB.sh

Remove the exec, it may block anything after it from running.

Hi Rich,
still the same.

This is what i did

Code: [Select]

sudo mkdir /tmp/theUSB
drive="`/sbin/blkid -lt LABEL=theLABEL -o device`"
sudo mount "$drive" /tmp/theUSB
sudo sync -f /tmp/theUSB/theSCRIPT.sh
/tmp/theUSB/theSCRIPT.sh
I'm not sure if that the correct sync command and position.
I think it should be invoked after mount instead of mkdir.
But no joy...

Hi curaga,
yes I did as Rich pointed out above.. But still same result.

Hi pek

... I'm not sure if that the correct sync command and position. ...

No, like this:

Code: [Select]

sudo mkdir /tmp/theUSB
sync
drive="`/sbin/blkid -lt LABEL=theLABEL -o device`"
sudo mount "$drive" /tmp/theUSB
/tmp/theUSB/theSCRIPT.sh

[Rich]

Hi pek
If the  sync  command does not help, change the first line of  /home/tc/mountUSB.sh to this:

Code: [Select]

#!/bin/sh -xAnd add these 2 lines immediately after the first line:

Code: [Select]

exec 1>/home/tc/debug.txt

Code: [Select]

exec 2>&1
Restart your machine and attach the the  /home/tc/debug.txt  file to your next post.

[pek]

Hi Rich, it still failed.

Here's the debug.txt

Code: [Select]

+ sudo mkdir /tmp/theUSB
+ sync
++ /sbin/blkid -lt LABEL=theLABEL -o device
+ drive=
+ sudo mount '' /tmp/theUSB
mount: /tmp/theUSB: wrong fs type, bad option, bad superblock on , missing codepage or helper program, or other error.
+ /tmp/theUSB/xyz/theSCRIPT.sh
cd: line 4: can't cd to /tmp/theUSB/xyz: No such file or directory
when I change the mount command into my original one, the debug gives

Code: [Select]

+ sudo mount -L theLABEL /tmp/theUSB
mount: /tmp/theUSB: can't find LABEL="theLABEL".

[Rich]

Hi pek
It's not finding the drive. Is the drives label actually  theLABEL ?

If you run this command manually does it find the device:

Code: [Select]

/sbin/blkid -lt LABEL=theLABEL -o device

Hi pek

If you run this command manually does it find the device:

Code: [Select]

/sbin/blkid -lt LABEL=theLABEL -o device

yes, it returned

Code: [Select]

/dev/sdb1
And the fact that everything runs properly when invoked "./.X.d/loadit" means all is named correctly.

I edited my reply before this.. i tried mount -L command and gives similar result.

[curaga]

Could be timing then? Your device's label is not yet known at that time?

[pek]

Possibly.. but i tried "sleep 9".. still nothing

Hi pek
Change this:

Code: [Select]

drive="`/sbin/blkid -lt LABEL=theLABEL -o device`"
To this:

Code: [Select]

drive=""
while [ -z "$drive" ]
do
drive="`/sbin/blkid -lt LABEL=theLABEL -o device`"
s l e e p 1
done
Remove the extra spaces in the  sleep  command.
