General :: Convert Ext3 To Ext2?
Mar 28, 2011I would like to convert my /tmp and /boot partitions from Ext3 to Ext2 on my Arch Linux setup. I don't see any use in having journaling for either partition. I want to make sure that I have the right steps lined up so could someone verify that this is correct (from a live cd):
Code:
#sudo tune2fs -O ^has_journal /dev/sda7
#sudo e2fsck /dev/sda7
#sudo tune2fs -O ^has_journal /dev/sda5
#sudo e2fsck /dev/sda5
I then edit /etc/fstab to reflect these changes (ext3 to ext2 for both lines)
Does it matter what order I do it in (/dev/sda7 is /tmp and /dev/sda5 is /boot).
General :: /var On SD Card :: Ext2 .vs. Ext3 .vs. Jfs .vs. Jffs2?
Apr 22, 2011We are running debian off of an SD card and want to know what's best for /var?
- Plenty of room on 2GB SD card, so do we, make /var as large as possible (everything else is read only) to reduce block overwrites, or do we make /var as small as possible, hopefully reducing the load 'pdflush' places on the 200 Mhz system?
That said, why not ext2? Is there damage that can happen in /var due to insta-crash or power loss that will prevent proper system function? We heard ext4 is more optimized, but ext4 on 2.6.29, not sure.
If we must use a journaled file system for /var, then which is lowest load on system, or "better": jfs, ext3, jffs2 ...
General :: Cannot Copy File Over 16,843,020 Kb On Ext2 Or Ext3 Partition
Aug 26, 2010i m not able to copy a file over 16 gigs on an EXT2 or EXT3 partition. Is there a way to do this. I even tried to split my iso file too. I splitted my iso file in 4 files then copy them on the ext2 or ext3 partition. But as soon as I was trying to join the files together it never went over 16 gigs. Actually it stops at 16,843,020 kb exactly. is there a limit for those partitions or is there an another way to see my 20gigs iso file in one piece?
View 1 Replies View RelatedGeneral :: Change Umask For Files Created In Ext2/ext3
Oct 28, 2009I have ext3 partition mounted on /mnt/shared/ as follows
Code:
Permissions above are of the actual mounted fs.
Goal is to have all files created on the fs
1) to belong to group 'users'
2) to have this groups permissions set to rw (rwx for directories) so that all users who belong to group 'users' have full read/write access to data and everyone else to have only read access.
Now because of setgid bit (s) in group permissions every file created has group 'users' and additionally setgid bit is set for directories. Because every users umask by default (on my system) is set to 0022 all created files will have permissions 644 for ordinary files and 755 for directories.
Net result of above means that users A and B who both belong to group 'users' won't be able to modify files created by the other.
So how can I make files created on the fs to be created always with umask 0002 WITHOUT changing default umask for users that is used elsewhere (like in their home directory) ?
Ubuntu :: EXT2 Vs EXT3
Apr 23, 2010I am planning on dual-booting Windows XP and Ubuntu on a new laptop, and because I have a program that lets me mount an ext2 filesystem on Windows, I was thinking of installing Ubuntu with ext2 instead of ext3. I am concerned, however, that it might open up a security risk for my Ubuntu partition. Would this cause a problem? (In case it's relevant, I use AVG Free antivirus in Windows.)

Nov 5, 2010I use 8GB USB sticks for backup of Ubuntu 10.04. I have had a variety of problems with ext3 format (security tar file not readable, etc) and have reformatted to ext2, so far without a problem.
But - am I missing something by not using ext3 (or even ext4)? Should I be sticking with ext3 and try to resolve the problems - bearing in mind that as the USB stick is my backup I need it to be secure!

I have always following messages ( occured in beta 2 too ).
But first before i continue - here my disk layout:

Fedora :: Convert LVM Volume Formatted Ext2 To Ext3?
Nov 5, 2010I have a question, i accidentally formatted an lvm volume as ext2 after creating it. Then of course, we copied a ton of data to it before I realized it was ext2. (I guess ext2 was the default when using mkfs without a -t) Anyway - can I just use tune2fs -j on the LVM just like I would a /dev/sdx device?

Fedora :: Hard Disk Data Recovery Of Ext2 And Ext3
Jul 1, 2010I am student of MCS and working on final project. I am the user of windows xp. I am new in Linux. I am working on a project that titles "Hard disk data Recovery of ext2 and ext3 in linux". In windows, including dos.h and bios.h header files in program of c language I can send interrupt to bios and access most of the devices like parallel port, hard disks etc. But problem is that there is no bios.h and dos.h files in gcc. Now how can I access my hard drive using c program. How can I call int13h interrupt in linux or there is any other function in the linux to access the hard disk. In fact I want to access sectors of my hard disk using c language program. How can I do it?

OpenSUSE Install :: Boot Error Because E2fsck Thinks Ext3 Filesystem Is Ext2 ?
Jan 19, 2010During the file system check of an ext3 partition at boot I get the following output:
The super-block could not be read or does not describe a correct ext2 filesystem. If the device is still valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate super-block:
I'm then forced to login in as root and given the following prompt:
I'm reluctant to do as advised by the output and run e2fsck -b because it is not an ext2 filesystem.
Although I can still enter runlevel 5, it doesn't seem to recognise mouse and keyboard input in KDE so my system is effectively redundant at the mo. For this reason any short term workarounds are welcome, but a fix is needed. This problem is part of a longer saga to do with recovering a Windows Vista installation which started failing to boot. I have used both Vista and SUSE tools to try and recover my bootloader to no avail, and this has been the result. If more detail about this is needed please ask and I can explain what I have done.
Server :: Mounting Ext3 File System As Ext2 On Slackware With Custom Build Kernel?
May 16, 2010I just rebuild the kernel for slackware 13, everything works, but root file system which is ext3 is mounted as ext2. Normally I've build ext3, ext4 and so on as modules, not in the kernel... but if I do this, then the kernel mounts the file system as ext2, which is build in the kernel. I also modified rc.modules so I can make sure that ext3,ext4,jbd are loaded, but it doesnt work.

Software :: List The Difference Between Two Files?
Apr 4, 2011I just upgraded my kernel to version 2.6.38 & I seem to have missed a few modules. I tried using diff to get a list of the differences between the files lsmod-2.6.35 & lsmod-2.5.38, which I created for this. Unfortunatly I can't seem to figure out the right syntax to do what I want which is to just show me whats missing. For example, I want to subtract the lines from file1 & file2 which are the same, leaving me with the difference in file3. i.e. file3 = file1 - file2 Is this possible or am I just using the wrong program.

General :: Recovering 1Tb Ext3 With Fsck.ext3?
May 20, 2011I Tarred and GZipped most of the data on one 1Tb partition and stuck the archives on a second 1Tb partition on a separate disk. I then proceeded to format the first partition with NTFS (from Linux.) The only problem is that I completely forgot that I had a CD drive and formatted sdc1 instead of sdd1! I began doing a full NTFS format and after a minute or two I cancelled it and decided to do a quick format. I then realized my mistake. I managed to find a copy of the superblock and began trying to recover the disk. fsck -t ext3 recognized the partition as NTFS but I luckily didn't have fsck.ntfs installed so it didn't touch it. I managed to get it working with fsck.ext3 (with -b,-B and -y) fsck.ext3 didn't mind that it was an NTFS partition.
Roughly how long will this take? It's running from Knoppix within a virtual machine to a USB hard drive which is 100% full. Days? Being that for a few minutes I attempted a full format am I going to end up with a bunch of corrupted archives? If I do end up with file corruption can anyone recommend a way of recovering the data / sorting it out? Is it likely to be just a few old files that are corrupt (It's my understanding that filesystems like to keep files in the same area on the disk to minimize the amount of head travel.) This might just be wishful thinking but as the filesystem fills up will ext3 put the newer files towards the end of the disk? If so then I'm hoping that a full NTFS format starts at the beginning of the disk.

View 3 Replies View RelatedGeneral :: Can't Delete The EXT2 Partition
Oct 31, 2009I had to install a new disk drive in my PC a week ago because the old drive died. The new drive is a 160 gig drive. First I installed Win XP with S/P 3 and everything was fine. Then I installed Ubuntu 8.04 and the troubles began. Ubuntu resized the Windows partition down to 8.81 gig and used the other 137.44 gig for Ubuntu. When I booted into Windows I started getting nasty little messages about "not enough disk space". SOOoooo....... I booted using the Ubuntu install CD and ran "sudo gparted" in a terminal window. I tried to resize the ext2 partition but got an unknown error.
Then I ran fixmbr in Windows to get rid of grub. Then I tried running gparted again to delete the ext2 partition. Got an error that said "can't delete the partition because it's mounted". So I tried to unmount the partition but got a message that the command "unmount" could not be found. After that I installed Partition Magic in Windows and tried that. It sees the ext2 partition but says it's unsupported when I try to delete or resize it.
I ran fdisk but it doesn't see the Linux partitions either, so I can't delete them in that program. I finally tried to format the disk but now I have a 9 gig drive with nothing on it. How do I get those Linux partitions off the drive so I will have a 160 gig drive that I can start over with? I've spent 6 days this week reinstalling XP and all of my programs, and now everything is gone because Ubuntu decided to be a disk hog.
General :: Recover From Deleted Ext2 Partition?
May 3, 2010I was installing windows vista on my computer, so I backed up everything to a external drive which was formatted with ext2. I then proceeded to install windows vista. When I got to the partition section I tried installing windows vista to my raid 0. When it didn't work I decided that I would delete all my existing partitions and create a new one. Well in my haste I accidentally deleted my ext2 partition from my backup drive that was still connected. As soon as I realized what I had done I shutdown the windows install and disconnected my external drive. This is the current state of my drive from parted:
Model: WD 15EADS External (scsi)
Disk /dev/sdb: 1500GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
I know that the drive only had one partition before and that it took up the entire disk and it was ext2 (maybe ext3).
