How to i can encrypt ext3 or ext4 file system.
I 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?

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 ?

I had 5.4 machine. Upgraded to 5.5 today via yum upgrade. All went fine. Rebooted. Wanted to convert root partition to ext4 (I have three partitions: /boot, / and swap). All of them on software RAID 1 (root is /dev/md2). I did the following for converting
yum install e4fsprogs
tune2fs -O extents,uninit_bg,dir_index /dev/md2
nano /etc/fstab # I indicated here that my /dev/md2 is of ext4

I'm wondering if anyone knows what will be Squeeze's default filesystem. Will it be the proven ext3 or the newer (sometimes faster, sometimes slower) ext4?
I currently have ext4 and I have nothing to complain about. In fact, my overall experience has been very positive. Ext4 is definitely faster when fsck runs during boot.
What would be the cons of having ext4 as default in Squeeze?
I'm using CentOs 5.4 (2.6.18-164.15.1.el5 #1 SMP Wed Mar 17 11:30:06 EDT 2010 x86_64). I tested out ext4 on a partition for the last few months and it seems to work fine. The issue is that quotas dont seem to work correctly on it. Is there a way to revert back to ext3? Mainly the quota tools do not work on it.

View 4 Replies View RelatedI have configured a "Syslog" server on /var directory as a separate ext3 partition - to receive the logs and events from the clients & the firewall as well. The directory needs to grow dynamically as the logs are populated. Is there a way i can make the filesystem grow dynamically as and when the directory is full.
View 6 Replies View RelatedWith the release of CentOS 5.5 ext4 is considered stable in this distribution so I decided to migrate to it. Luckily I started from migrating fresh server with CentOS 5.5 using some instruction I found on the internet. I think I shouldn�t say, that I screwed the whole thing up ;) After about 6 hours cursing, kicking, and crying I solved the task and figured the correct sequence of actions. The small problem with migrating root partition is that you can�t unmount it BTW.
During migration task, I found, that CentOS 5.5 rescue mode is somewhat broken a little in terms of ext4 support. It can mount ext4 partitions successfully. But its e2fsprogs package (tune2fs, e2fsck etc.) doesnt see ext4 partitions and say, that superblock is corrupted on a partition once is converted to ext4 (at least it did it for me. May be I should force filesystem type with -t ext4 switch?). Keep in mind, that if you screw your system up too badly, you will not be able to run tune2fs and e2fsck on it from rescue modeBut you will still able to mount it if it is not corrupted badly. In all below examples,Boot your system normally and login as root. Upgrade kernel if you wish (I usually use yum upgrade to upgrade all on new machines). Then upgrade/install some other packages

View 3 Replies View RelatedI 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.
I 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.
I 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.
I 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:
Desktop/
Desktop/
Documents/
Documents/
Downloads/
Downloads/
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:

I'm trying to figure out why files in linux are oriented in the folders the way they are. In Windows it's much simpler to picture. You have program files (C:Program Files(x86), system files (C:Windows), user settings for programs or personal stuff(C:User), and some weird folder names. I was noticing that the Ubuntu ext4 filesystem is a little more complicated. Some folder names are self explanatory, but others are not. Is there a guide, or some reading material on the history of the linux filesystem and how it morphed into what is presently used in Ubuntu?

I 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?
I accidentally formatted a HDD when I meant to format a USB thumb drive. The HDD is a 250GB drive that had about 180GB of data in the EXT3 format. I was actually attempting to make a bootable USB thumb drive with TRK (Trinity Rescue Kit). Kind of funny/ironic to mess up a drive while trying to make a rescue disk. Anyway, as soon as I realized what had happened, I pulled the drive out of the computer to make sure I didn't do anything else stupid to it. I have been searching for some way to recover and haven't really found much. There are a lot of programs to get Windows data back, but I haven't seen anything specific on the EXT3 file system.
View 4 Replies View RelatedI'm trying to mount a second hard drive as a ext3 (rw_acl,user_xattr). I type the ff.:
