Fedora :: Convert The Ext4 Root Partition To Ext2
Oct 31, 2010I have a usb flash drive and according to sources I found out after the fact that I should have used ext2 instead of ext4 due to the extra write operations.
Is it possible to convert the ext4 root partition to ext2 or do I need to backup, reformat, and restore?
CentOS 5 :: 5.5: Migrating Root (and Any Other) Partition From Ext3 To Ext4?
May 20, 2010With 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
Ubuntu :: EXT4 Root Partition Errors Not Corrected At Boot Check?

Ubuntu :: Disk Space Is Wrong On Root Partition?
Jan 15, 2010My root partition seems to be full bur is wrong because I have a partition with 15Gb space and the data is arround 7.5Gb I have:
Quote:

PHP Code:

/dev/sda5 15G 14G 660M 96% /

When I look for specific info about what is taking the space using du command I get that the space used by the root system is 7.2Gb. I get to the same conclusion when checking the space with Nautilus.

Ubuntu :: Ext4 Partition Recognized As Part Of Original NTFS Partition In Fdisk
Jul 18, 2011I just installed ubuntu via the windows executable and I couldn't mount my NTFS partition. I found this a little odd and I checked fdisk and it seems to think I don't have an ext4 partition as my entire internal HD is displayed as NTFS.
Here's the fdisk output:
When i try to mount the NTFS partition /dev/sda2 i get the following output:
I can't make heads or tails out of this. Anyone know what's going on here?
Windows recognizes that 30GB were taken from the NTFS partition for my linux install. It reads the max partition size as 465GB. fstab reports the NTFS partition size as 488GB.

OpenSUSE Install :: 11.2 - Root Ext4 FS Corrupted On SDA6
Jun 2, 2010I was unable to boot into my system after I'd just shut it down, so I tried repairing it using my installation media... only to find that though my root Ext4 fs on sda6 was corrupted & *supposedly* repairable, the cd could not do so for some reason! All I can get is a command line, saying something about the root fs being mounted as read only, and I have no idea how to resolve this. I cannot afford to loose ANY of the data I have on here.
View 2 Replies View RelatedFedora :: Shrink Down The Ext4 Partition Which Has Ubuntu On It?
Feb 11, 2011Currently I have a four partition setup: One ext4 /boot partition for Fedora, one LVM partition, one ext4 partition (which has Ubuntu), and one swap partition. What I would like to do is shrink down the ext4 partition which has Ubuntu on it and increase the size of my LVM parition (and increase the Volume Group, filesystem, etc. within the LVM). However, I've been searching on Google and the only solutions I find is to make the free/unpartitioned space and then create a new LVM partition and stretch the VG over the two LVM partitions. However, I already have 4 partitions, so I can't make the fifth one.
Is there any possible way I can increase the size of the underlying LVM partition itself?

Oct 5, 2010I have recently updated my ubuntu 9.10 install to 10.04. And with that I've tried to install snow leopard on my computer so i can dual boot between them.the install was successful, but grub2 (that worked fine) wouldn't see the OS X install on its own partition. so i tried reinstalling it, like you do after you install windows and it would remove grub as the bootloader.That didn't work and i got a lot of messages that it wouldnt work because my partitioning (or something like that) is GPT. by the end of it i didn't have grub installed at all!so i started playing around with GParted, and while doing that i also put a bios_grub flag on my main ubuntu install partition, thinking that it would force grub to load from that partition. But that just gave me the GRUB Rescue prompt when trying to boot.
So i unchecked the bios_grub flag. and now it doesn't boot to anywhere and when inserting the ubuntu live cd i cant even see the ubuntu ext4 partition and mount it.Gparted says that its a partition that its File System is undetectable and unknown.Is there any solution that will allow me just to mount that partition and copy files from it?

View 9 Replies View RelatedUbuntu / Apple :: Boot Directly To Ext4 Partition?
Apr 30, 2010I am dual booting Ubuntu 9.10 with ext4 and OS X with hfs+, and I'm getting tired of having to go through Open Firmware, rEFIt, and GRUB to boot to Ubuntu by default. I've done a lot of digging, and my results appear to be inconclusive. I have, however, been able to hypothesize that the reason that I cannot set my ext4 partition as the Startup Disk (via OS X settings) is because OS X does not know how to read ext4. I believe that the Startup Disk settings work by writing to Open Firmware, so I'm thinking that maybe something else would be able to as well, preferably something that is capable of reading ext4.
