HOTPLUG_ERROR

[kudos]

I am experiencing a HOT PLUG ISSUE with my livecloned SalixLive CD LXDE 13.1.2 Frugal Install via Legacy Grub which I will try to describe below.

Please Note that the SalixLive CD LXDE 13.1.2 is working nicely and this experience is with my livecloned Frugal Install which includes many extra packages.

The following sequence of THREE windows occur when CLICKING on a newly hotplugged pen drive or sata Hard Disk Partition in PCMan File Manager.


1/ "Unable to mount device" window appears with following message:

Error <i>org.freedesktop.Hal.Device.Volume.UnknownFailure</i>

CLICK on OK yields

2/ another identical window with the same message:

Error <i>org.freedesktop.Hal.Device.Volume.UnknownFailure</i>

CLICK on OK yields a third window

3/ called "Error" with the following message:

Directory doesn't exist!

CLICKING OK yelds no further window.

df in an LXTerminal indicates that the device sdc and it's three partitions are not listed:

I then tied MANUALLY MOUNTING in an LXTerminal as AS FOLLOWS:

one[~]$ su
Password:
root[one]# mkdir /mnt/sdc1
root[one]# mount /dev/sdc1 /mnt/sdc1

NOW df shows the mounted /dev/sdc1 on /mnt/sdc1 properly as follows:


root[one]# df

/dev/sdc1 305136 305136 0 100% /mnt/sdc1

root[one]# ls /mnt.sdc1 DOES SHOW ALL THE FILES PROPERLY ALSO.

NOW going back to PCMan File Manager DOES show the Partition with the it's CORRECT LABEL and CLICKING on it shows the contents.

SO, I suppose it is a hot plug issue.

Final Note: I am booting from a Frugal Install using a Legacy Grub with following menu.lst entries:

title salixlive 13.1.2 LXDE
root (hd0,1)
kernel /boot/vmlinuz root=/dev/ram0 rw quiet
initrd /boot/initrd.gz

NEWS FLASH !!! NEWS FLASH !!! NEWS FLASH !!! :)

I just noticed that PCMan displays /media when clicking on a partition when booting from the CD Itself

BUT PCMan displays /mnt when clicking on a partition when booting from my livecloned Frugal Install

THEN I looked for /media after Frugal Install Booting and there is NO /media directory.

Upon perusing liveclone.py, I wonder if it is possible that LINE 483 is the culprit ?

Tx for the report, I'll look into this too.

I imagine that in your frugal install, you only used the module created by liveclone which means that the rootcopy skeleton where media was created is missing. I actually didn't foresee this usage of LiveClone. I'd better rethink some things.

You did point in the right direction. Could you try to replace both lines 482 & 483 by this one line (making sure you keep the same indentation):

Code: Select all

subprocess.call("mksquashfs /bin /etc /home /lib /media /opt /root /sbin /srv /usr /var " + live_workdir + "/salixlive/base/01-clone.lzm -keep-as-directory -b 1M -comp lzma -wildcards -e 'media/*' '... *pid' '... wicd/*-settings.conf' ", shell=True)

I think that should fix both issues you brought up. Please let me know. Tx.

[kudos]

Akuna,

A VERY POSITIVE REPORT:

Booted a vanilla LXDE from Optical Drive
spkg 49 Packages (431.2 MB)
RAN the "MODIFIED" LiveClone
23 min later, the ISO was created.
Dropped it into /base on my pen drive containing the Frugal Install
Rebooted Nicely
EVERYTHING IS WORKING.
!!! GREAT !!!

Nice work. By the way I was very happy to see that you wrote it in Python. I will mention this when I speak about Python

IMHO SalixLive is really shaping up and 64 bit will be the "Cherry on the top"

One question, do you believe that this "Modified LiveClone" would work on SalixLive KDE, xfce, Fluxbox or are there different LiveClones for each ?

Thanks again for the LiveClone in the first place and for your help

Same LiveClone for all editions of SalixLive CDs.
Thanks for the report, I'll include the fix on SVN.
