Description

I have a failing SSD drive.

I was using Kubuntu Linux as usual, when the system became slow and certain operations (that required write access to /var/) started to fail. The root / partition was suddenly mounted read only!

I tried to reboot the system, but it wouldn't book anymore. Basically. my root partition was on a failing drive! I am currently using a live disk to access the internet.

I'll try to document as much as I can as I try to recover as much as I can.

It still won't mount:

       missing codepage or helper program, or other error

Mounting the image works, though:
# mount -o loop ./ssd_root_drive_sda1.iso /mnt/image/

augustin - 08/25/2011 - 10:12

Basically, my problem is similar to this fellow's:
http://forums.linuxmint.com/viewtopic.php?f=49&t=60411
who got no answer either...

Since we can make an image of the partition and actually mount the image... what is the best course of action???

#16

augustin - 08/25/2011 - 10:18

Now that I have an image of the drive, and at least access to the most important configuration files I wanted, I'll try to reformat and cp everything back.

I install gparted on the live disk:
# apt-get install gparted

#17

augustin - 08/25/2011 - 10:21

Hmmmm.... that's interesting. When opening gparted, it sees /dev/sda1, as well as the total size, the amount use and the amount of free space... How does it do this, since the partition is not mounted?

#18

augustin - 08/25/2011 - 10:24

Using gparted to fsck the partition gives the following error (in gparted_details.htm)
e2fsck: unable to set superblock flags on /dev/sda1

Creating a new partition doesn't work either!

I bought a new Intel SSD drive to replace the old one. Still within the live CD session, I plugged it in via a USB adapter, formatted it and copied all the root data over from the image of the old drive I had done previously.

Then, I unplugged the computer, physically replaced the old drive with the new one, but the computer didn't boot. It's probably because I forgot to update /etc/fstab with the new UUID and update grub accordingly.

Used blkid to find the UUID of the new drive and updated /etc/fstab.
