Fedora :: Recovering An Encrypted Partition?
Apr 8, 2010
I have been using fedora 12 for last 6 months, recently I bought an external USB hard drive of 320 GB capacity. I made 2 partitions using the Disk Utility in Fedora. I encrypted the first partition as it was supposed to hold a lot of sensitive data, and yes it did have. Now I had to change my OS to AV linux for some audio-video editing work which wasnt being done properly on fedora due to some issue beyond my knowledge. now the problem is my encrypted partition is not accessible in my new installation. I see an empty space on my /dev/sda1. although no change to partition data has been done and the data on the second partition /dev/sda2 is easily accessible. when putting the drive on automount, is does not ask me for the password and neither does it show me the data. I have tried fdisk and sme other utilities but have failed to get my drive unencrypted.

I recently suffered a hard disk failure, meaning I had to replace the faulty device. After attempting to mount the old faulty hard drive using and external caddy, I got the following message... Unable to mount 144 GB Filesystem Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb5, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
I'd like to attempt to recover what I can from my /home directory but unfortunately I use encryption (although I do actually know my pass phrase). What procedures and software can I use to try and recover data from this drive?

I have recently recovered from an HDD failure on my Drobo. One of the disks died and corrupted the entire array (which is not supposed to happen). I have since managed to copy the data off onto smaller disks and after replacing the failed drive, have copied everything back.
Now that im up and running again, i was wondering how this situation would play out on encrypted disks, or in the case of a drobo a large encrypted partition (as you cannot encrypt the entire array).
Would i still be able to recover the data if i were to encrypt it? It is a 4.2TB array, and i assume that I would need to copy the data in its entirety to recover it, so using multiple smaller disks would be out of the question right?

I have installed fedora 11 in my system. While installing it asked me encrypted password which i passed. But I forgot that. Now the problem is whenever i boot my system before going to root itself it is asking for volume encrypted password, which as i told you i have forgot. Now i am not able to access my hard disk since it is completely locked. Is there any way to decrypt the password or unlock it. Or if that is not possible can data be recovered,which is my primary requirement..

I purchased a larger hard drive to upgrade my HTPC running MythTV and a Samba file server. I put the old hard drive into an e-SATA enclosure and can still boot to it to access my files, but I can't seem to mount it correctly under the new installation to copy over my files even though I have the mount passphrase and encrypted filenames key.I have tried using this howto, but I run into problems with the encrypted filenames.This is how I'm doing it. I replaced the actual key data with A's and B's to protect my keys:
Code:
$ sudo -i
# ecryptfs-add-passphrase --fnek
[code].....

Let's begin from the top. I have a relatively new laptop that I've been running Ubuntu on (along with a little-used Windows boot). Picked it up in November or so, installed the current "latest" version of Ubuntu at the time (9.10). I have been doing incremental upgrades, and it's been progressively breaking down more and more. Yes, this includes 10.04.
After GRUB stopped working, I decided it was time to try a reinstall from the top. I told it to leave all the other operating systems alone and do a full reinstall.
Fortunately, I had managed to stuff most of my current work in duplicate locations during this whole debacle, somehow. Don't ask me how I managed to do that when GRUB wasn't working. However, when I installed, I conscientiously said "Oh, yes, Ubuntu, encrypt my home folder! I love privacy!" As a result, about... 30 gigabytes of useful (but ultimately re-downloadable) material is rather inaccessible at the moment. When I try to boot the old system using the newly fixed GRUB, it goes into kernel panic. This seems like a no-go.
I have a saved hojillion-character long passphrase for decryption from my install back in November. Conscientiously saved in the case of just such an emergency.
I read this how-to and followed it to the letter as far as I could tell, trying to mount with ecrytfs to recover my data.
[USERNAME] here is a proxy for my actual username. Yes, the location of my old home folder may seem a little bizarre.
Code:
sudo mount -t ecryptfs /media/c82ca9fe-2b15-4aca-a98d-6482b1d80a32/home/[USERNAME]/ /home/[USERNAME]/oldhome
Passphrase:
Select cipher:
1) aes: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)

I'm running Debian Squeeze AMD64 with full disk encryption and LVM. After reinstalling Windows 7 I lost GRUB from the MBR. I managed to install GRUB after following this guide and using an Ubuntu 10.04 graphical installation disc, but I only get to a GRUB CLI when booting, so I can't actually choose an OS there.
I tried following this guide but I'm stuck after "# Mount the partitions to /mnt/root" and don't know what to do.
Does anyone know how I can fix GRUB so I get to choose between Debian and Windows 7 there?

I used Ubuntu for years now, but since the latest decisions got public I deceided to try something new: Fedora. I installed the system as a dualboot,Ubuntu and my old data. Because Fedora got installed inbetween of two partitions,ad to do the partitioning manually. I just made one partition /dev/sda4. During the installation process I got asked about the password for my /dev/sda1 partition. Of course, I entered it. So far so good.Now, everytime when I boot, the boot process stops and asks me for the password of the /dev/sda1 partition. However, the boot process does not go on, unless i press STRG+C.After the log in, I can also not access my data, by entering the password (GUI).The only way I can acces the data on that partition is:
Code:
su -
cryptsetup luksOpen /dev/DEVICENAME luks-fedora
[code]...

Somehow my file encryption password changed so when I went to re-install Fedora it said SDA-2 will not be available during installation.Is there a way to erase the whole disk including the ecrypted portion?

I keep my /boot partition on a usb stick, where i keep the keyfile as well. I already generated the keyfile and added it to the LUKS LVM partition.Right now, on bootup I get a nice GUI to enter my 40 character password which is nice but a little tedious What do i need to modify for the system to automatically unlock the partition with the keyfile that is stored on the /boot partition

I encrypted my /home partition in my last installation F13. For some reason, I have to reinstall F13. After I login, I can not access /home. I followed some instructions like
modprobe dm-crypt
modprobe dm-mod
cryptsetup luksOpen /dev/vg_vit/lv_home vg_vit-lv_home
[code]...

I need to access /etc/modprobe.d on an encrypted LVM LUKS partition. I m not sure how to go about it though. Mount usually handles my mounting needs, do I need to decrypt the physical volume first? LIst of commands need would make my day.

I have encrypted a partition while installing Fedora 13, and I need to disable its automount - I will mount those manually.
But even though I commented out the corresponding line in /etc/fstab, I am still asked for the passphrase for the partition at startup.
How to completely disable this behaviour - and how to mount the partition manually afterwards?

I just picked up a 1.5TB external drive. I want to wipe the NTFS partition (I assume that's what it is) that is there and replace it with an encrypted ext4 partition.
Is there a HOW-TO somewhere for this?

couldn't find anything similar on the forum.I am writing a kickstart for fedora 14 with a partition table similar to:
part / --asprimary --fstype="ext4" --size=10000 --encrypted --passphrase=pass1
part /boot --asprimary --fstype="ext4" --size=130
part /var --fstype="ext4" --size=5000 --encrypted --passphrase=pass1

Anyone had any experience with unlocking a LUKS encrypted root partition via ssh? It is ok to leave /boot unencrypted.
There are a few pages from google with the debians variants, archived by putting dropbear into initrd.
I like to do that with my fedora/centos remote servers, but struggle to find any resources specific to it. Anyone has any suggestions and thoughts as to what might be a suitable way forward?

I need a FREE solution that can image an entire Luks system encrypted volume and the rest of the used HDD, the MBR and /boot partition. Note: MBR and /boot are not encrypted. Note 2: I want to be able to restore entire drive from image with only a couple of steps. Note 3: Destination HDD space is a factor. Image file must be compressed and the image file must be around 40 to 50 GB or less. The smaller the image the better.
I have used clonezilla live cd before but not for encrypted volumes. I know you can install it in Linux. But, I don't know how to configure it after installation. I would be very happy if someone could tell me how to configure clonezilla in Fedora. How to guides are also welcome. I have one more question. If I image the encrypted volumes and all the stuff I mentioned above while logged in to Fedora, and I restore the drive from the image, will the recovered drive still be encrypted?

I was trying to delete a logical drive in windows xp and the damn disk management tool in windows not only deleted my other windows partition but also my linux /data ext3 partition. Now I have a unallocated space in place of these partitions. The data is still there but the entries in the partition table have been removed. So how do I recover my partition. I was trying to use the following tutorial. [URK]
I used the sudo parted /dev/sda -- and then rescue START END command and could get back the /data partition. But it gives me the following error while mounting the partition. mount: wrong fs type, bad option, bad superblock on /dev/sda7, missing codepage or helper program or other error. In some cases useful info is found in syslog - try dmesg | tail or so.
What does this mean. How to I fix this? Also when I try to recover my windows partition using parted it scans for a while and then does nothing. It doesnot ask for writing the lost partition in the partition table. What do I do?

After realizing 10.04 Final doesn't support Intel 855 graphics card the hard way (upgrading to 10.04 from 9.10), I did some very silly things and now cannot even choose past kernals or go into failsafe graphics mode (which had worked prior to this).Long story short I screwed up GRUB. Because I am an amateur end user.I still have the 10.04 live cd. Can I reinstall this to put GRUB back to the original state?

I just installed kubuntu 10.10, replacing an older installation. I have three hard drives one of which had all of the data I wanted to save, about 500gb. I repartitioned and formatted the other two drives and made sure that the data drive would be mounted but not formatted. When I booted into my new installation, the data drive was blank. I'm not sure if it's relevant, but I had just upgraded the file system from ext2 to ext4 before starting the installation.
I've been trying to recover my lost partition with testdisk. The website has instructions for recovering a formatted partition. It looks like it's working until the instructions tell me to choose Boot and RebuildBS, which I don't see as options. Can anyone give me any advice on how to recover? How did this even happen? Has anyone had a similar issue with installation?

I recently accidentally corrupted my windows vista partition whilst trying to extend it via gparted under ubuntu 11.04 and then cancelling it shortly after starting. Resulting in me being unable to boot into vista (I don't have another copy of any windows OS so I'd really like not to have trashed this one )
Looking on gparted now my partition is Fat32(?) and apparently only has 36mb used =/

I had a tri boot of Win 7 /XP and Mint...I was using EasyBCD 2.0 as a boot manager...I booted Mint by configuring the NeoGrub option in Easy BCD..I wanted to uninstall Win 7 and so what I did was the following
1. Edited BCD bootloader settings ...Marked XP as my default and deleted Win 7 entry...
2. Logged out and wiped my Win 7 partition
With my fingers crossed , i rebooted but Easy BCD booted flawlessly with 2 choices XP and Mint(GRUB)...As Easy BCD is not meant for XP, I thought of restoring original NTLDR of XP so that things would be in place and thinking that this cud avoid problems of detection by other Linux OS I deleted manually the Easy BCD menu.lst file and NeoGrub.mbr in my root...That was it , after I rebooted, I got boot screen of EasyBCD but whichever option I select,I got an error message that address not Valid-NTLDR not found or something like that I booted my XP live CD and like many times before ran
1.Fixmbr
2.Fixboot
3.bootcfg /rebuild
After that , now when I reboot , I am getting "Invalid Partition Table" On booting from a linux CD , I can see the files are in place..I have to get boot sector and partition table fixed...

I've tried to resize my home partition using parted. Prior to it I had removed ext3 flags following some advices found on net. Resizing failed and I ended up with filesystem bigger than partition. Then I managed to enlarge the partition using fdisk but it didn't help. When I run fsck on it it prints:
Code:
fsck from util-linux-ng 2.16.2
e2fsck 1.41.9 (22-Aug-2009)

Something bad happened to my partition table,so right now I'm working from a Live CD. My partition table is completely screwed, although the data on the lost partitions hasn't been overwritten. I've been messing around with TestDisk for about an hour, but I still didn't figure out how to fix my problem. Before the crash, I had 5 partitions:
NTFS - 30GB
NTFS - 8GB
ext4 - 20GB
and here comes the extended partition:
linux swap - 8 GB
NTFS - 400GB
TestDisk can see all those five partitions. I can mark swap as Logical, but I can't do so with the 400GB NTFS partition - there is just no selection. Turning on "expert mode" didn't help. I have read about using sfdisk to fix partition table, but I don't think I'm able to do it by myself.
Here's how it looks in TestDisk:
Code:
Disk /dev/sda - 500 GB / 465 GiB - CHS 60802 255 63
Partition Start End Size in sectors
D HPFS - NTFS 0 1 1 3915 254 63 62910477
D HPFS - NTFS 3916 0 1 4959 254 63 16771860 [Windows XP]
[code]....
I've filled sizes according to TestDisk's findings. First 3 partitions were OK, the problem lies in the extended partition holding 2 logical ones. By the way, TestDisk is able to enter the 400gb partition and see the files.

I have an external USB hard drive that I need to recover some data from, but I see from fdisk -l that the partition uses LVM:
Code:
[root@localhost ~]# fdisk -l /dev/sdd
Disk /dev/sdd: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[code]....
I've followed various lvm tutorials all of which describe setting up lvm from fresh on empty disks. Unfortunately non mention how to 'install' new a drive that was previously set up with lvm. I have had a go anyway and may have now lost my data. Here's what I've ended up with (the partition in question is sdd1):
Code:
[root@localhost ~]# pvdisplay
--- Physical volume ---
PV Name /dev/sdd1
VG Name vg02
[code]....
I've tried mounting with other fstypes, but all give the same error.
