Security :: Encrypt Entire File System - Fedora 11 64bit?
Jul 11, 2009I recently installed Fedora 11 64bit and I am curious about encrypting my entire file system for security purposes. I've been on Google for a while now and I keep finding info on how to encrypt a specific folder or home directories but nothing on the entire file system (or I'm missing something big here). It's hard for me to imagine that it isn't. If so, do I need to encrypt the partition my file system is on before installing it? What software should I use? There seems to be so many, it's difficult to keep them all straight.

Jul 7, 2011I was in the process of installing Ubuntu 11.10, but got stuck choosing which file system to use. ext3 and ext4; which is better for a personal desktop? If ext4 is better, will it work well on my old PC (bought 3 years ago), or perhaps ext4 is not actually compatible with an old hard disk?

Sep 7, 2009How well is the ext4 new file system mounting compatibility with the older ext3 previous Linux installations ? I refer to Ubuntu 9.04 and the new Fedora 11 which have the option to install with the ext4 file format. Will it be better if I install with the older ext3, so that I will be able to mount all other Linux from each other in a multi-boot system ?

View 4 Replies View RelatedUbuntu Security :: Ext3/ext4 Full Disc Encryption Performance?
Feb 3, 2010I've been using full disk encryption with luks on two Dell laptops for about 2.5 years. One is 64 bit Fedora (upgraded to 12), another is 32 bit Ubuntu (upgraded to 9.10), both were ext3, until recently.Over time, performance degraded substantially, especially on Fedora, which was put to a heavier use. That laptop has 4 Gb RAM, two 2.5 GHz T9300 CPUs, and 56 Gb of free space.
It was especially unbearable after a reboot. Programs like firefox and thunderbird would take close to a minute to start when ran for the first time after a boot. The login process was painfully slow, and some Gnome applets (e.g. Tomboy notes, keyboard layout switcher) would fail to load on the first login, with an error. I experienced this problem on both laptops with full encryption. I had to log out and relogin to make the applets appear. I tried various boot and mount options and was thinking about switching to ecryptfs (encrypted home).
I also use 3 desktops with no encryption and a netbook with ecryptfs on /home, which all work fine. All are Dell, 2 Ubuntu and 2 Fedora. The Gnome applets problem seems to be due to slowness of the installs with the full disk encryption. The last thing I tried is to migrate ext3 to ext4. I also converted /home, /usr, /opt to extents, following[URL].. That seemed to do the trick. Gnome applets now load fine on both laptops, and startup time is back to tolerable.
Is this a typical experience: ext3 performance degradation with time and a much better performance with full disk encryption once ext3 is migrated to ext4?
Ubuntu :: Converting Ext3 To Ext4 On An Installed System ?

View 3 Replies View RelatedUbuntu Installation :: Cannot Boot System After Migration From Ext4 Down To Ext3
Mar 22, 2010I have been able to get most of the way through the process of changing from using ext4 back to using ext3, but something is not quite right so my system does not boot properly.
I have a system that was running Karmic Koala 9.10 as a server (no graphical environment). I had two drives using RAID1 with LVM on top, where the logical volumes of oldvg (old volume group) were using mostly ext4. /boot was not part of the RAID: it's on a separate physical drive and uses ext2.
I recently added two more drives and used RAID1 and LVM, and made all lv partitions (/, /usr, /var, /tmp, /opt, /home, /srv) ext3. I used rsync to duplicate the contents onto the logical volumes of newvg (new volume group). I was careful with rsync's option switches, and this part seems to be fine.
I also edited (the new) /etc/fstab and changed the UUIDs of the seven mount points to point to the logical volumes that are part of newvg instead of oldvg, and added new entries to (the new) /boot/grub/menu.lst to refer to newvg in addition to those that I left around to refer to oldvg.
This wasn't sufficient: rebooting here failed, but I went in with a rescue disk, and first updated /boot/grub/device.map to include the new physical drives. I then mounted all the new logical volumes, mounted boot also at its proper place, and entered a chroot of the new system as it should be mounted. Once there, (and after making a backup of /boot) I ran "update-initramfs -k all -c" to rebuild the initrd images that were stored on /boot. Finally, I also edited /etc/mtab so that the two entries that referred to oldvg now refer to newvg instead.
Now, the machine begins to boot from newvg, but the console text includes messages like:
And a bit later,
Now, at this shell if I type mount, I see:
I am actually confused as to why there are only entries for /root and /var in /etc/mtab, actually, instead of entries for all of the main mount points. I am thinking it must be part of the boot staging process, because there are entries for newvg-usr, newvg-tmp, etc. in /etc/fstab.
When I type any of pvdisplay, vgdisplay, or lvdisplay, I get
In fact, even if I run lvm, I get a similar error:
However, if I go back to the rescue cd, pvdisplay, vgdisplay, and lvdisplay do show that all of the partitions from both the old and new volume groups are available.
Debian Configuration :: Live Migration To Ext3 To Ext4 On A LVM2 System
May 5, 2011I have successful upgraded my system from Lenny to Squeeze and have even installed NVIDIA Driver successful, as well as other applications that I need. My system is now running smoothly and okey. My applications are also running smoothly except Skype 2.2 (Debian Forum Guys are currently helping me solve it).
However, I do want to upgrade my file system to ext4 in order to take its advance features and advantages especially that my system is now in WORK HORSE mode. However, I am not confident enough to do it because the guide is limited and does not tackle the issue of a system using ext3 with LVM2 on it.
Therefore, my question is how do I migrate (LIVE) my Ext3 to Ext4 on my system that uses LVM2? A clear and understandable guide is highly appreciated especially that I am newbie on it.

Fedora :: Evaluate The Ext3 File System Performance
Apr 13, 2010I need evaluate the ext3 file system performance; i need define:
- services provided
- parameters and
- the performance with different parameter values; for example, changin the value of the "data" parameter (journal, ordered, writeback).
I do not know what services ext3 provides. Well, i know intuitively that it provides services to read, write and erase files. But, there are anything more?. Where can i find the API?. Is the ext3 file system POSIX compliant?
Fedora Installation :: F11 With Ext3 Instead Of Ext4 - Crashed Or Failed
Jun 14, 2009It has crashed or failed to install on a known good system for the 5th time now. I have never had that problem with fedora before. I am now installing with ext3 instead of ext4. I am hoping for better success with it and will update. I was able to try MinGW with WINE before the first crash and I liked what I saw there. Only hoping to be able to get a good install this time.
View 2 Replies View RelatedFedora Installation :: 'Upgrade' Filesystem Ext3 To Ext4 While Upgrading ?
Jun 11, 2009Is that possible, I mean when I upgrade F10 to F11 with yum upgrade is there a way to 'upgrade' the filesystem to ext4 for example (with the exception of boot partition)? Or I have to reinstall fedora like new?
While changing the filesystem can I do it by parts? what I mean is for example: I have 2 partitions like '/' and '/home' with ext3, so I backup data in '/home', change '/' to ext4 then mv files from '/home' to '/' and change '/home' to ext4 and finally mv those files from '/' to '/home'. Is that possible?
Fedora Installation :: 11 - Can't Be Mounted When Booting After Converting From Ext3 To Ext4
Jun 16, 2009I upgraded F10 to F11 successfully.
Then I convert the / partition filesystem by the following steps:login as root user in multi user mode read [url], and execute tune2fs -O extents,uninit_bg,dir_index /dev/mapper/VolGroup01-LogVol00 modify /etc/fstab, change the type of / to ext4
reboot
(because fsck say running it on a mounted filesystem can cause filesystem damage, so i decide to reboot to single user mode first. maybe it's a mistake here) try to boot F11 to single user mode, failed
reboot from a SystemRescueCD-1.2.0 LiveCD
run e2fsck -fpDC0 /dev/mapper/VolGroup01-LogVol00 in SystemRescueCD-1.2.0 LiveCD, no error reported
reboot
try to boot F11 normally(multi user mode), but it failed at: EXT3-fs: dm-0: couldn't mount because of unsupported optional features (40).
I tried rescue mode of Fedora-11-i386-netinst.iso after these steps above. The / partition can be found and mounted to /mnt/sysimage correctly. I can read/write files in / partition, and i can even yum new softwares in rescue mode, but it just can't be mounted when booting.

(b) what is the best method/application to do this?Ubuntu gives an option to encrypt the partition via the installer.

I am predominately using Ubuntu 10.04 i686 with the ext4 filesystem.

Jan 10, 2011I used the ext3 format when I formatted my partition prior to installing Ubuntu10.10. I had accidentally deleted a file and began the process to get it back. It wasn't critical but helpful to recover the file. To make a long story short I ran into to some unexpected road blocks. I tried to use PhotoRec to get the job done but with no success.
I'm just looking down the road in the event I might have to recover something important.If it would be better going back to the Fat32 file system I would rather do it sooner than later. Just as a side note I am dual booting between linux and windows.
Ubuntu :: Ext4 File System Hosed After 11 Upgrade (duplicate Directory & File Names)?
May 8, 2011I recently upgraded to Ubuntu 11 and a few days later my ecryptfs filesystem began misbehaving in a weird way. In my home directory, many subdirectory names are duplicated verbatim. Here's an ls -F excerpt:

I can no longer access files in those directories (if I ls the directory, it appears empty; I can cd to it, but there's nothing inside). Not all of the directories are duplicated/damaged like this, but most are. A few non-directory files are also duplicated in this fashion, so for example:
