I need to convert my server(10.04) to ext4 from ext3 and want to make sure I am going to do this the correct way.
Edit fstab to ext4
Code:
sed -i s/ext3/ext4/ /etc/fstab
Run the tune2fs command, the filesystem is mounted is this ok?
Code:
tune2fs -O extents,uninit_bg,dir_index /dev/md0

I have installed ubuntu to my pc. i made 3 partitions. one for system, one for data and one for swap. two of them were ext4. after some time i have reinstalled ubuntu again. but this time i didn't put to format the second partition, but just mount it using ext4. after that i cannot open my files. checked with gparted shows that 2GB used, but with df 188MB. and in properties writes ext3/ext4 filesystem. i used chown, chgrp but didn't help. please help, these data are ver important. i cannot lose them.
View 7 Replies View RelatedHow can I format a USB hard drive to ext3/ext4 or whatever file format and have full permission to read, write and execute all files afterwards? When using the command line (as ROOT of course) mkfs.ext3 /dev/sdb? Restricts the rights to ROOT as does the procedure gParted. The man mkfs did not help much. Configuring the fstab- file is a bit of a hassle, so it would be nice, if there was an option to set the permissions "correctly" right from the beginning. Setting Ubuntu (I'm using Ubuntu 9.10) up, so that it mounts USB devices not as ROOT as default but giving all users all permissions seems to be really complicated, as a guy from my local LUG told me.

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?
View 4 Replies View Relatedis there a way of sharing an ext3/ext4 formatted partition on an external USB drive between different users (uids) on different Linux machines without creating a group for this purpose, setting the group ownership of the partition to this group and adding each respective user to the group on every machine?This would mean that I need to have root privileges on every machine... which I may not have in some cases.I'm using the partition to store the code I'm developing on Linux and I would like the option to be safe... if possible.I could use a vfat partition but then I have no control of the rw rights + I cannot develop directly in the dir: I would always have to tar.gz the directory, extract, work, tar.gz, copy to the external drive.

View 4 Replies View RelatedI 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).
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 ?
View 6 Replies View RelatedOS: Debian unstable 32bit, kernel 2.6.32-2, grub 1.98 from late january 2010 (only have working net-access from work now, so I am grabbing information from memory). EXT3 and EXT4 support is compiled into the kernel along with chipset/scsi/sata support (not as modules), and I have tested to boot ext3 with it before proceeding. Prereq: my old disk started to have too much S.M.A.R.T errors, so I bought another one, put in a USB cabinet, added swap and ext4 partition/filesystem to it, and copied over all data from the old system to the new that was mounted at /dest using the command "find ./ -xdev -print0 | cpio -paV0 /dest". Swiched disks, so I now have the ext4 disk sitting at /dev/sda (partitions: sda1 => ext4, sda2 => swap), and booted into rescue-mode from cdrom, using /dev/sda1 as root with a shell on. After doing this, I performed the following commands:
mount --bind /dev /dest/dev
chroot /dest
modified the /etc/default/grub to instruct the kernel to boot using ext4, ran grub-install --recheck /dev/sda
ran update-grub to modify /boot/grub/grub.cfg (which looks as it should) After doing this, grub finds my partition and mounts it. It however stalls with the message: "warning: unable to open an initial console" and does nothing after this point. I have no ramdisk, but my old kernel booted fine from ext3 (and still does if I copy it to a ext3 partition), and since the ext4 support is compiled into the kernel - should I really need a ramdisk?
Is there guide for converting ext3 to ext4 on Fedora? I use Fedora 12 which is regularly updated. How safe is procedure for data, I have only one ext3 partition on disk which has one ntfs and that ext3 partition (and also one small swap partition).

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.

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

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.
I have a drive with ext3 that was my old /home drive.When I moved to 9.04 I went with ext4 and just linked to my old home drive.My old ext3 drive is becoming unstable so I want to back it up.I have a 500gb ata drive (unfortunately not a sata drive) thatto wipe and put 10.04 on. I want to move my data from this backup driveIm going to back up to, to the new 10.04 until I get another hd as abackup drive.My question is, I know there is some issue between ext3 and 4 and I dontwant to get into a bind. What would be the best format for moving
View 3 Replies View RelatedI'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 have Debian Squeeze with linux-2.6.32-5-amd64Ok, so what I did is first changed fstab ext3 to ext4, rebooted, everything looked good. Then I enabled extents and other ext4 features on my root and home partitions using commands
tune2fs -O extents,uninit_bg,dir_index /dev/sda3
tune2fs -O extents,uninit_bg,dir_index /dev/sda4
then I ran e2fsck -fDC0 /dev/sda3

It 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 4 Replies View RelatedI compiled a kernel using a previous kernel config after I switched to the ext4 file system. Previously it was using ext3 and the kernel compiled and ran fine. I added support for ext4 to the config but when I went to boot I had a kernel panic. The error was "kernel can't mount vfs on (8,5)". Root is on sda5, I don't know what the 8 is. I started over, using mrproper and made a new config, but got the same error. I created an initrd with the ext4 file system but then the kernel said it couldn't mount root on ext3 because of unique options. (something along those lines) I booted back into the default kernel and saw that it had a similar error right after the bios check, but it loaded fine. I'm wondering why the kernel is saying that the ext4 file system is ext3.
View 11 Replies View RelatedThe ext4 features are well listed in the Ext4 Howto.
Most of these features seem to be aimed at newer systems, having petabytes disk drives and handling huge files -- neither of which applies to my system.
Can a modest 3 year old system, having only two 500GB HDDs, used mostly for Android development using Eclipse (64-bit), benefit from choosing ext4 over ext3?
With 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
