Fedora :: Can't Resize Encrypted / Home In LVM
Feb 13, 2011
Recently installed Fedora 14 64 bit on a hardware RAID 1 from distro DVD, and set up an LVM with an encrypted /home partition. I now need to resize (enlarge) the /home partition and have not been able to do it due to system-config-lvm telling me:
"Logical volume is not mounted but is in use. Please close all applications using this device (eg iscsi)"
I have tried doing this logged in as user, and also as root. I've tried with a Live CD, but an additional problem there is that the Live does not recognize the hardware RAID and tells me I have the same /home partition in two devices, which are the two disks in the RAID array, and refuses to resize.
I found this link:
< https://help.ubuntu.com/community/Re...ptedPartitions >
which details a rather complex process to achieve what I want, but I am wondering if there is an easier way ?...
PS... forgot to mention I have been able to successfully resize all other LV's within the LVM, so I am assuming it is the encryption that is causing the problem....

fter my first fedora 10 installation I reinstalled FC 10 keeping my home partition from the first install.I then installed a software as a USER which indeed installs applications on USER's home. Now I'm short of space for installing the applications and so I want to resize my existing home (of USER).Can this be done without reinstallation? Can I borrow needed amount of space from the home partition of 1st install.also I have unformatted and unpartitioned free space can this be made use of? Or the only way is to reinstall

I'd like my /home partition to be encrypted. Does this need to be selected during installation (I don't remember seeing an option) or can it be enabled after installation?
How stable is this with ext4 on Fedora 11?

I encrypted "/" and "/home" during boot with F12. Now I'm trying to install F13. The problem is it will not allow to specify /home as the mount point. It will take /home and not complain but when I get back to summary there is no mount point, just blank. When I entered the passphrase it didn't complain so I think that is okay. The / dir I said I wanted to format, so it accepted the / mount point.
I tried to go ahead and install F13 anyway thinking it may figure this out. However it didn't use my /home but created a new /home.

I have let the debian installer set up with separate partions forrootusrvarhometmpIt ended up with a huge home partition and little place for the others.So I wanted to give some of home's space to the others and didlvreduce on homelvextend on the others.Following some info on the net it tells you toe2fsck -f partition1 followed by aresize2fs partition1But when I try to fsck the reduced home partition I got the following error:The filesystem size (according to the superblock) is 73113600 blocksThe physical size of the device is 20447332 blocksEither the superblock or the partition table is likely to be corrupt!Abort? yesIs there any way to save this?

l my root (/) partition has 11G free space and my /home is only left with 5g around and /usr has around 8g in my fedora 13 .So is there any possibility to "resize" the root partition and add it to home partition bcoz i see the opposite in the threads(resize home to add space to root).My home has nothin more than a movie which is 700MB and i've installed some new application yesterday. But it shows half of the space is almost used!!!
/dev/sda7 12G 925M 11G 9% /
tmpfs 497M 2.6M 495M 1% /dev/shm
/dev/sda9 12G 5.0G 6.0G 46% /home
/dev/sda8 12G 4.1G 7.3G 36% /usr

I need to disable my encrypted home directory because it prevents me from logging in with my fingerprint scanner when I first boot up. I'm running kubuntu 9.10.How do I do this?Also, how would I revert back to it being encrypted if I decide to not use the fingerprint scanner for initial log in anymore?

Dummy me let root run out of space because I didn't know to use logrotate. I was able to compress the system logs but not before the damage was done me thinks; now the computer is unbootable. I booted from a LiveCD and got my old partitions mounted under /media/oldroot to try and recover files; however, I forgot that I had encrypted my home. I found [URL] and was following it; however, I seem to run into a bunch of path issues after I chroot.
The chroot command returns:
bash: groups: command not found
The su command returns:
-su: cut: command not found
-su: getent: command not found
-su: expr: command not found
-su: groups: command not found
Finally, the ecryptfs-mount-private command returns:
-su: ecryptfs-mount-private: command not found
I have separate partitons for /, /home, /tmp, /usr, and /usr/local and bothered to mount the first 2. (If only I had been ambitious enough to create a /var). I was running Ubuntu 10.10.

I have choosen to encrypt Ubuntu 10.10 during installation (no alternate installation). After some time of working properly I get following error message after I put in correct password :
"Could not update ICE authority file /home/surf1/.ICE authority"
When I click "ok" following error message is shown :
"there is a problem with the configurationserver (/usr/lib/libconf2-4/gconf-sanity-check-2 finished with status 256)"
When I click this "ok" next error message appears :
"Nautilus could not create following necessary files : home/surf1/Desktop,/home/surf1/.nautilus"
After I click here ok nothing else happen anymore and I get not access to my account and so to my data.

After update to 11.4, I would like to regain access to my encrypted home that I left intact. Both user.img and user.key files are there, but when I create the same user again in YaST, it does not recognize their presence and it asks again for size of the image. I am afraid it will just overwrite the old image. I do have full backup of hte data, but since its 150GB, I would rather not have to transfer it again.
How can I remount my old encrypted home?

I installed Ubuntu Server because I want to learn Linux and I want to learn about servers. I did a newbie tutorial and then shut down. When I booted up today, the files in my home directory were replaced by Access-your-private-data.desktop and readme.txt, but I have no idea why. I followed the instructions in readme.txt and typed ecryptfs-mount-private. It told me
INFO: Your private directory has been mounted.
INFO: To see this change in your current shell:
cd /home/rmob
But if I do ls /home/rmob, it still shows me Access-your-private-data.desktop and readme.txt instead of the files I created there yesterday. Every time I reboot, it tells me
keyctl_search: Required key not available
Perhaps try the interactive 'ecryptfs-mount-private'
If I try ecryptfs-mount-private again, it still tells me it has mounted it, but still just shows me those same two files. Googling about this tells me this means the directory got encrypted somehow. I tried typing touch ~/.ecryptfs/auto-mount which I found in this tutorial, but it didn't make a difference and I can't find any other solution anywhere.

I'm recently switched my work laptop from running winXP to runing karmic. I'm still at the stage of getting my various bits and bobs working correctly. One of these I (may) have a problem with is backup's. I've ran backuppc on a ubuntu 9.04 box in the attic for the last year or so and I've been backing up my laptop to that. But since the switch, since I have an encrypted home dir, what is being backed up is the encrypted files. First, can I recover these if needed (I kept a copy of my passphrase), or can I get backuppc to ssh in as me with my home dir mounted correctly?
Backuppc is using rsync over ssh I've been using linux on and off since about redhat 5.0, so I'm not afraid of the command line or vi

I recently did a clean install of Ubuntu 9.10 and when I did I chose to have /home on it's own partition and have it encrypted. The more I think about it the more I regret this decision. What if I want to switch distros down the road? What if I have to boot from a live cd to back up files? Is there a way to "undo" the encrypted home folder permanently? I don't mind having it on it's own partition, it's just the encryption that makes me worry.

I recently installed Ubuntu Karmic on my netbook (I tried netbook remix but preferred the look of the regular desktop edition). When during installation, the option to encrypt the home folder appeared, and being mildly paranoid I thought, "sure, why not?" (I must warn you that I am a new user with little technical knowledge other than what I have managed to gather in a semi-passive manner over the past couple of months). The problem is, I (try to) backup my data weekly, and so today I gave it a shot (I got the desktop edition a week ago). I have encountered the following problem.
I backup my system following (approximately) the instructions at [URL] for Backup The exact command I enter at backup is:
sudo tar -cvpjf 2010.02.13.tar.bz2 --exclude=/proc --exclude=/lost+found --exclude=/sys --exclude=/mnt --exclude=/media --exclude=/home/dan/music /
(I exclude my music folder as it is huge and I already have it all in several other locations) When I executed this command all ran smoothly for a while, however it soon began backing up the directory /home/.ecryptfs/dan/.Private At this point, it started backing up the huge number of files in this directory. I assume these are encryption keys? Forgive my ignorance... Anyway, it took several hours going through this folder, and finally bzip gave up, complaining of excessive file size:
bzip2: I/O or other error, bailing out. Possible reason follows.
bzip2: File too large
Input file = (stdin), output file = (stdout)
I assume that excluding the encryption keys and such from the backup would be a bad idea: I guess that if I did not restore the relevant directories along with my home folder, it would be inaccessible? Is there a way to avoid backing up such a large amount of data?

During the installation of Ubuntu Karmic, I picked the option that encrypts my home directory.
A few questions:
(1) Shortly after installation, I was asked to run a command to print a key necessary for data recovery from a rescue CD. I didn't run it at the time and am now looking for the command to run. What is it?
(2) I think I read somewhere that this also encrypts swap. Great. Correct me if that's wrong.
(3) If I suspend the machine, is my home directory encrypted? That is, if I have this on a laptop and travel with the suspended laptop and someone steals it, are my data safe, or not?
(4) I assume the weakest point in the system is my relatively short login password (but I think the install tests it and found it okay). Is there a recommendation how long this should be?

I ran fsck on the wrong partition (which was mounted) and in my haste blew up the file system on that partition. Now here's the kicker, I had 450Gb of data and documents on that partition that was in an encrypted home directory. So the long and the short of it I ran fsck again and I was able to recover all the files, and they are now residing on a Lost+Found folder on my hard drive.I have located the encrypted files, but I don't know what to do with them.

I have a dual boot WinXP / Kubuntu system. Recently, I tried to upgrade from 9.10 to 10.04. I have my Kubuntu partition set up with separate partitions for / , /home , and swap. Naturally, I wanted to wipe the slate clean, so I formatted / and left /home alone before doing the install. However, my /home partition was encrypted with the standard crypto that you get when you install. I just deleted the way in by wiping my / partition. Now all of my files are on my drive but encrypted. I do have the unencrypted passphrase given to me when the hard drive was first encrypted, so I am sure there is some way to get my files, but I am unsure how to apply it.

I've upgraded to my old dell from Xubuntu 9.10 to Xubuntu 10.04 and set up separate /home partition. I chose to encrypt the /home folder when I installed. I'm wondering if that's the quick answer for why I can no longer sftp from my Ubuntu Jaunty laptop. Both machines are on my desk, and I've been happily using ssh to get files between them before this. The Xubuntu machine has openssh server and client installed, the Jaunty machine has only ever had only the ssh client. Now I get a popup saying "Could not open location ..." and the sftp address, and "Host key verification failed." I've not done much with this new install, so I don't mind just re-installing again. I don't need an ecrypted /home, but I do want very much to be able to continue to ssh into that machine. Is it my encrypted /home that's causing this?

so, after long time of succesfull use of kubuntu, i encountered a 1st major disaster yesterday while using kphotoalbum. It has somehow frozen my machine in so mighty way, that it apparently corrupted a directory with majority of my pictures , which now appears to be empty .My home lies on a separate partition, its encrypted aand using btrfs and I am using kubuntu 10.10. So, could anyone give me some clues how to unencrypt my home partition, that i could obtain an image of partition or whatever else usable for photorec to check for pictures?

I did some minor upgrades to my 10.04 box which grew and grew and grew until I'd hosed xorg, and after some unwise choices about uninstalling X11 as a means to rebuild the system I now have a drive I was using for 10.04 that basically doesn't have an O/S any more... don't ask! First class stupid.Anyhow, I've cracked open a new drive, installed 11.04 and was planning to mount the old /home/me folder as a symbolic link from 11.04. All that was fine until I remembered that 1) I no longer have an OS on my 10.04 drive and I've encrypted my home folder on the 10.04 machine. That home folder is still intact, but obviously not much use right now.
So, have I just hosed myself completely (as I suspect) hosed myself or is there a way to capture the cleartext data from the encrypted folder and move it into the 11.04 machine, either with rsync, restoring the O/S to the formerly 10.04 drive and restoring the encryptied /home to that drive?
Goal 1) recovery contents of encrypted folder to plaintext, but lacking ability to log into O/S that generated the /home folder
2) move data to 11.04
3) attach the cleartext verison of home to my 11.04 account and get to work.

I am trying to open an encrypted home directory from opensuse 11.2 with opensuse 11.3. This means i have a user.img and a user.key So far i have done:
losetup /dev/loop3 user.img
cryptsetup luksOpen /dev/loop3 home
Enter passphrase for /dev/loop3:
No key available with this passphrase. At this point it will not accept my passphrase.
A luksDump reveals:
cryptsetup luksDump /dev/loop3
LUKS header information for /dev/loop3
[code]....
When i try to use the key file, i get:
cryptsetup luksOpen /dev/loop3 home --key-file home.key No key available with this passphrase.

I am having a problem setting up an encrypted home directory with openSUSE 11.3. I used Yast User and Group Management to edit an existing user to encrypt the home directory and the user.key and user.img files were created in the /home directory. I tried it out and logged in as user and created a new file. I logged out and logged in as a different user and was able to see the newly created file in the first users home directory.
I figured I did something wrong so I went back to Yast and deleted the user. I deleted the /home/user directory using file manager su mode. I tried again to create a new user with an encrypted home directory using Yast and now when Yast tries to write the changes I get an error: "pam_mount is already setup for user. Use --replace to replace the
existing entry." I do not know how to proceed from here except to try with a different user name as I do not understand what the error message means and what command to use --replace with.

I'm guessing that a file is created as a loopback device and encrypted (using LUKS?)
What is the mechanism used at user login to decrypt and mount the encrypted $HOME and to re-encrypt it at logout?
I confess an ulterior motive here - SWMBO has recently got her hands on an Acer Aspire one running Linpus Lite and there's absolutely no security on it
Personally I'd dump Linpus and put on openSUSE but it's her box and she likes the simple interface that Acer have supplied so maybe I can set up the encrypted $HOME as YaST does for openSUSE if I can find out what to do.

First off I'm new to the openSUSE community and would just like to say So, to the issue at hand. I recently switched to openSUSE 11.4 from Debian. I noticed the setup didn't have an option encrypt the home folder like it does in Debian, so not being aware of any other way to encrypt it, I created a new partition, backed up my current home directory, created a new partition and mounted it as home before copying in the contents of the backup to the encrypted home partition I created. Now of course it is askingme to put the crypto password in at each boot, which isn't ideal because it's a family machine and no-one would remember the password but me. Is there any way of being able to automount the encrypted partition without having to put the key in every time? Or better yet an encrypted home folder that doesn't require the key to be put in on each login (as in Debian) without even using a dedicated partition.
