General :: Stuck Choosing Between Ext4 And Ext3 For The File System?

Jul 7, 2011

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?

General :: Ext4 New File System Mounting Compatibility With The Older Ext3 Type?

Sep 7, 2009

How 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 ?

OpenSUSE :: .jar File Runs Fine In Command Line But Not From File System?

May 3, 2010

My .jar file needs and uses some files in the same directory it's in (everything, including the jar was unzipped into said directory). It runs perfectly when I do java -jar file.jar in the command line, but there's trouble when I double-click the file when running from the file system manager. I've tried a custom command under properties ie java -jar, but the problem is that the .jar file doesn't seem to be able to use any of the files in the same directory. When running, the jar can't find any of the files that it needs.

Ubuntu Installation :: Cannot Boot System After Migration From Ext4 Down To Ext3

Mar 22, 2010

I 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, 2011

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.

CentOS 5 :: 5.5 Ext4 Conversion - Ext4 Partition Is Recognized As Ext3?

May 19, 2010

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

Ubuntu :: Ext4 File System Hosed After 11 Upgrade (duplicate Directory & File Names)?

May 8, 2011

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:

General :: Recover A Deleted File Using The Ext3 File System?

Jan 10, 2011

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.

Ubuntu :: Corrupted EXT3 File System?

Feb 9, 2011

I am using Ubuntu since release 8.10, but it is first time when i can`t solve problem

when i tried to create new NTFS partition on unallocated disk space with Paragon Partition Manager (damn, that was stupid). Process was aborted with error (later i finally made it with Gparted without problems)

After reboot mine Ubuntu say:

Code:
Errors were found while checking the disk drive for /

Press F to attempt to fix errors, I to ignore, S to skip mounting or M for manual recovery. I pressed "F" but that had help only for a boot and doesn`t really fix error :`(

Later i booted from liveCD and had checked partition (/dev/sdb1; file system - ext3) with gparted (result - aborted fixing process with error) Now i can`t even boot from that partition and even mount it from other linux system.

mine fdisk -l
Code:
/dev/sdb1 * 1 5957 47849568 83 Linux - problematic partition (unmountable)
/dev/sdb2 5958 29983 192988845 7 HPFS/NTFS

[Code]....

PhotoRec recover most of my files, but i need complete partition.

Ubuntu :: Ext4 File System ?

Aug 6, 2010

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?

Ubuntu :: Filesystem Ext2 - Ext3 And Ext4 ?

Apr 30, 2010

I run an upgrade and an update on a lucid lynx beta 2. --- got no problems. but about the filesystems i have some questions because it seems for me that at every system boot the system will run an fsck. somtimes it's shown up, somtimes not. but in /var/log/messages and in syslog

I have always following messages ( occured in beta 2 too ).

But first before i continue - here my disk layout:

And here my filesystem types:

This is my problem because those values are seems to be static ! ( note: this partiton is mounted but not in use ) and last not least: the drive is an external usb scsi disk. but on the other side lucid lynx is running fine on my box.

Ubuntu Installation :: Ext3 Vs Ext4 When Upgrading To 10.04 From 8.04?

Sep 7, 2010

I am going to do network upgrade of my 8.04 to 10.04 LTS. I have a dual boot with Vista, and currently I can read Ubuntu partition from Vista using Ext2fsd. However, I read that using Ext2fsd with ext4 (default in 10.04) is problematic because of "extents".

My questions: Will the upgrade convert my current ext3 partition into an ext4 one? How can I keep the ext3 partition? The release notes for 10.04 say:

The simplest way to select a different file system such as ext3 at installation time is to add the partman/default_filesystem=ext3 boot parameter when starting the installer.
