Recovery DVD failure

[lmfs]

Has anyone used the recovery DVD that comes with the A-110? Linpus DVD, that is.

I just tried and while it boots to a certain stage it fails while (b)unzipping the root image to a ramdisk (/dev/ram1). The image is larger than the allowed ramdisk size.

Creating a USB recovery stick works alright, but I'm not able to recreate the disk using the DVD.

That didn't help the OP at all. You missunderstood the question.


Problem bellow is solved. As I suspected a normal USB pendrive worked.


I'm in a similar situation, I used another computer to create an USB image to a SD-card. When I boot (on the A110) with the SD-card (plugged to an external cardreader) I get the following error message:

intel_rng: FWH not detected
sd 2:0:0:2: [ssd] Assuming drive cache: write through
sd 2:0:0:2: [ssd] Assuming drive cache: write through
finding LiveCD...
finding LiveUSB done, it is .
unziping rd-base.img.bz2...
bzip2: Can't open input file /mnt/rd-base.img.bz2: No such file or directory.
bunzip2 error, maybe memory not enough?
I'll open a shell for you
sh-2.05b#

In the current directory where the shell starts (the "old" root) there is a file called linuxrc, a shell script.
The command that fails (and thinks the memory is not enough) is
bzip2 -d -c /mnt/$RDBASENAME >/dev/ram1 || bzerror="error"

but /mnt is empty, /dev/ram1 exists so I think their is some error earlier.

I've installed 1 GiB memory (so I have a total of 1,5 GiB RAM), only change I've made to my AA1. And I think it would be strange if this is causing the problem.

Here is a full printout of the linuxrc file:

#!/bin/sh

mount -n -t proc proc /proc

# define the rdbase name
RDBASENAME=rd-base.img.bz2

# find and mount the cdrom device which contains rd-base.img in it
echo "finding LiveCD..."
usbinst=`cd /dev; echo sd*1`

for tmp in $usbinst; do
    mount -n -r -t ext2 /dev/$tmp /mnt 2>/dev/null
    if [ -f /mnt/$RDBASENAME ]; then
	  bootdev=$tmp
	  break
    else
	  umount /mnt 2>/dev/null
    fi
done

if [ "X$bootdev" != "X" ]; then 
	#echo I believe the CD-ROM device is /dev/$cdbootdev.
	# save the CD device for remounting later
	if [ "X$CMDLINE" != "X" ]; then 
       if [ -b /dev/ram2 ]; then
	      echo /dev/$bootdev > /dev/ram2
       elif [ -b /dev/rd/2 ]; then
	      echo /dev/$bootdev > /dev/rd/2
       else
	      echo 'Can not find a RAM disk device /dev/ram2 or /dev/rd/2!'
		  echo I will not be able to determine CD-ROM device.
	   fi
	fi
fi

echo "finding LiveUSB done, it is $bootdev."

# bunzip rd-base.img.bz2 now, and made a real root in ram
echo "unziping rd-base.img.bz2..."
bzip2 -d -c /mnt/$RDBASENAME >/dev/ram1 || bzerror="error"
if [ "x$bzerror" = "xerror" ]; then
    echo "bunzip2 error, maybe memory not enough?"
    echo "I'll open a shell for you."
    exec /bin/sh
fi
echo "unziping rd-base.img.bz2 done."

#mount -n -r -t ext2 /dev/ram1 /new_root
mount -n -r /dev/ram1 /new_root
echo "0x100" >/proc/sys/kernel/real-root-dev
cd /new_root
/bin/pivot_root . initrd
hash -r

umount /initrd/mnt
umount /initrd/proc

As seen it the script runs through sd*1 like trail and error (I only have sda1 and sdb1). I checked and sdb1 is not a medium it said. Maybe it is one of the other ports in the memory card reader (4 slots for different kinds). I don't have any 2 GiB USB pendrive right know, that's why I'm using the SD-card.

... That didn't help the OP at all. You missunderstood the question...

Au contraire, I believe I did understand the original poster's question, but my response may have been open to misinterpretation. I believe the OP may have fundamentally misunderstood how to use the Recovery DVD, and I therefore directed them to a post that explains its correct use. I agree that that post does not describe the same problem, only that it is another example of how not to use the Recovery DVD. I should have made that clearer. I apologise. I'm curious to know, however, how you are so certain that my response did not help them? Of course, they may very well have known that they were using it in an unprescribed manner. I concede that that may have been the point of their post.

Whatever the case may be, I am not altogether clear what point you are trying to make regarding the contents of the bash script? I realise that you are trying to create a Recovery SD instead of a Recovery USB, but again this is another example of how not to use the Recovery DVD.

By the way, the "not enough memory" error is a red-herring. I think, the problem with the script is that it cannot find the recovery disk archive file, possibly because it cannot mount the SD device, possibly because it is not a USB device. But I could be wrong. It has been known It is obviously possible to boot from an SD card. It may just be that the Acer Recovery Management System is not setup to do so. Or, that you are using the wrong SD port on the One. Without further investigation, I just don't know. Let us know what you discover
