my second partition on sda needs to be wiped out and i want to use dd to restore a backed up filesystem to it. can this be done without using mkfs? i don't want ot use mkfs because it is a ssd and it won't restore the nand to factory condition.
View 4 RepliesI recently did a clean install of 11.04 Beta, and I must have done something wrong with the mount points during installation, which resulted in me having a different home folder mount point or something. The old partition on which I have my home folder needed to be mounted manually. I did that once, and then upon reboot, I couldn't access the partition anymore. Disk Utility now shows the partition as "unknown filesystem".
The output of fdisk is as follows (if that helps at all):
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
[Code]....
On a side note, I tried using TestDisk to restore the partition, but I only created a DD image of the damaged partition, but now I'm stuck, as I'm not sure how to mount it, or if it's possible to retrieve files if I succeed in mounting the image.
I have created two logic disks /dev/VolGroup00/LogVol00 and /dev/VolGroup02/LogVol02
After reboot has disappeared /dev/VolGroup02/LogVol02
How to restore logic volume?
I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage
*Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?
are there any sweeper / cleaner apps which can take back my installation as to when it was new. I know home directory could have config files etc..but that doesnt matter, i want all packages and applications reset to how it was when i had a clean install. I am using Natty

This only started happening quite recently - before this I could boot to Linux quite happily.
I am trying to mount a file image, like this
mount -o loop /tmp/apps.img /media/apps
But I get the following:
mount: you must specify the filesystem type
I try ext3:
mount -o loop /tmp/apps.img /media/apps -t ext3
dmesg says:
error: can't find ext3 filesystem on dev loop6.
I've also tried ext2, vfat etc. How can I detect the filesystem type of apps.img?
I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.
I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

I've been doing a bit of customization on my ubuntu install and have added "auth required pam_fprint.so" to my pam.d file in order to allow fingerprint recognition upon boot. After rebooting, I discovered that my fingerprint reader no longer functions (I get the message "Module is Unknown"). I was wondering how I could remove those lines from the common-auth file. I have tried booting a live CD and typing "gksudo gedit mnt/etc/pam.d/common-auth", but when I try to save, I get the error "Could not find the file /home/ubuntu/mnt/etc/pam.d/common-auth."

View 2 Replies View RelatedMy friend's computer is giving him the blue screen of death (have to LOVE Vista), so I decided to help him. I am pretty sure that it's from a virus that corrupted Vista, but I could be wrong, it could be the hard drive that went corrupt. Being that it's a laptop, I am hoping it's just the OS.
Now, I have Ubuntu on a disc, and it runs very smoothly. (Didn't install it, just chose run on the disc.) However, I couldn't see the files on the computer. I was wondering if there is a way to get those files without installing Ubuntu, because I am planning on upgrading the computer to Windows 7, but using the Ubuntu disc was the only way I could actually get to the desktop.
So, I guess my question is: is there any way to get the files from the computer on the C drive without having to install Ubuntu
I have remastersys backup on DVD but I have no idea how to restore. There is install option when I boot from DVD but it doesn't install anything to hard drive. It looks as if my system was loaded to memory or was run as LiveCD.

here's the situation: My WD external drive got the tables corrupted from being improperly ejected, I plugged it in and after mounting, The entire folder hierarchy was there, but none of the folders showed any data in them, it seemed that they were empty, but disk still registered being 40%full of data)After digging around on google/forums I discovered that what might be wrong was a damaged superblock.I unmounted the external HD and ran gparted to "fix" the problem. It deleted the file names and now after mounting the drive in Nautilus it seems like they have been deleted for real...I'm normally very careful about my data but now I'm afraid that i've lost everything! i'm still hopeful however because running fsck on /dev/sdb1 it still prompts me to delete "orphaned long entries" which i haven't done yet.

View 3 Replies View RelatedWhen I used KDE 4.3.1 with Slack 2.6.29.6 kernel, there were no option to shutdown the computer from KDE. I always had to log off, then issue a "sudo /sbin/halt". The same goes for the reboot option.When I tried XFCE and Gnome Slackbuild on the same kernel, I noticed that there was options to reboot and shutdown. But when I compiled a new 2.6.33 kernel, it seems such options disappeared from Gnome. I didn't check XFCE.
How can I restore it to Gnome, and add it to KDE? I tried looking in the kernel config, but couldn't figure out which option is related to that.
