General :: Ext4 Partition Turned Into Unknown According To Gparted?
Jul 7, 2010
I was using gparted to resize my /var partition, which is supposed to be an ext4 partition, and during the beginning stages of the resize/move procedure I cancelled out of the process despite the warning this might be bad. The process was in the middle of the "read" stage so I figured nothing can go wrong during a read, but now I cannot access this partition mount wise. Is there anyway to repair this?
I have 3 Ubuntu installations & a PCLINUXOS, plus Windows XP installed on one hard disk. I still can boot to each one of them and can mount each one using Ubuntu.
The problem "may" have occurred when I reduced the size of some linux partitions using gparted. I still have plenty of space in each of those partitions.
When I started gparted all of the HD was unallocated. I did that from each ubuntu installation and the PCLINUX installation, plus LIVECDs. All indicated the space was unallocated.
When I did an fdisk -l from a Puppy Linux LiveCD I got a normal start and ends of each partition.
When I tried it from Ubuntu installation or live cd, I received the following types of responses:
Code: ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda5
Disk /dev/sda5: 28.5 GB, 28566397440 bytes 255 heads, 63 sectors/track, 3473 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System ubuntu@ubuntu:~$ sudo fdisk -u /dev/sda5
The number of cylinders for this disk is set to 3473.There is nothing wrong with that, but this is larger than 1024,and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Plus the Windows partition seems to go over its limits.
Since all of my OS installations are still working, I don't know how critical this is. From reading another post, I understand this might be able to be fixed by making some changes in fstab.
I want to convert a vfat partition into an ext4 partition. This is on my wife's machine and she deleted the Windoze partition as she now prefers Linux. Here is the (edited) output from fdisk -l:-
/dev/sda2 514048 4708351 2097152 83 Linux /dev/sda3 4708352 6805503 1048576 82 Linux swap /dev/sda4 52693200 234436544 90871672+ f W95 Ext'd (LBA) /dev/sda5 59006800 234227699 87610446 83 Linux
I want to change /dev/sda4 to 83 to free up space for Linux without losing the partitions in this 'extended' partition!
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
Ok my current issue is that my ubuntu partition(my currently most used os) at the moment is getting low onspace so i decided to take 40GB from my windows one since it wasn't using it. I made it smaller and left the area unallocated. I got into gparted using the live disk and it refuses to work for me. I cannot move my ext4 partition to the 40GB partition and put that free space at the end. This is the first time i've ever had this problem. This is the first time i've ever tried ext4.
i had an ntfs partition..i formatted it to ext4 with gparted..w i cant write any files to it..i think because gparted executed with root previliges so it has now made root the owner of the drive.
The following is a screenshot of GParted run on my system. There is a small unallocated space at the beginning of the list. This 1 MiB space is kind of annoying and I'd like to merge with any other partition except /dev/sda1, /dev/sda6 and /dev/sda4. When I right click on the unallocated partition, the only available operation is "New". And, if I click on "New", I get the following error message.
It is not possible to create more than 4 primary partitions
how to go about merging the small unallocated space with other partitions?
I have 3 partitions on my hdd right now, a Windows 7 one, the associated System Reserved and my Linux Mint partition. I was trying to use GParted to make another partition by splitting my Linux Mint one in two smaller partitions. I can't, however, unmount it, and so can't partitions it. I have considered partitioning it from Windows 7, but I'm afraid it will screw some things up and stop booting up correctly. So, what could be making the partition unable to unmount?
I tried to repartition my hard (320GB) drive yesterday because I need (40 GB) more space in windows, below I mention the previous file system and later file system architecture. It is dual boot (windows 7 and Fedora 13). I am sorry that I did not take screenshot!
1. boot partition, 100 MB 2. windows-7, around 75 GB 3. extended, around 230 GB
inside extended 3 logical partitions:
3a. 125 GB for backupv(NTFS) 3b. 4 GB for linux swap 3c. 100 GB for linux
I used gparted. Since I had to create more space in between windows and logical partition for increasing windows, (I could not shrink Linux as it comes to the end) so I removed Linux (I reinstalled later) first, moved (hold in the middle and drag) backup partition to the right by 40 GB, created a primary partition out of the left portion of logical partition and merged with windows. Finally installed Fedora on the right most portion (60 GB now) in the logical partition. Now my file system looks like following;
Now my problem is, I don't like that 7.84 MB unallocated space in the logical partition. I was told that it (smaller than the smallest chunk gparted can allocate to any partition) will always be there unless we allow some program to do the partitioning automatically rather than I manipulate/move it manually? It is true? If so is there (m)any software which can do this? Or simply how to get rid of this unallocated space.
First of all, the boot device is an 16GB SD card. I install Citrix XenServer on it but I make the partition too small (XenServer makes a lot of logs file). I resize the partition but now it give "Illegal OpCode" and red screen everytime it boot.I already create the image of the whole SD card using dd and already try these process three times = restore the image, test that it can boot properly, then resize the partition using gparted, then it can't boot.
I already post this question in XenServer forum (with screenshot) but nobody answer there.The hardware itself is HP Proliant ML350 G6 with internal SD slot.
I am trying to create a partition using gparted for my centos installation but I accidentally deleted my partition table. my partition was created on windows7 and dual boot with ubuntu. I am trying to recover it using test disk with ubuntu live cd but after I recover it still I neither can't boot on windows or Ubuntu here is the result of patition quick seart
I realise that this is not a pure Linux Q, but I am hoping for tolerance and even help!After removing the partitions (/,/home) that held an older Linux installation, gparted showed the original Windows XP partition followed by the new unallocated space. On rebooting, there was a Grub rescue error (text not noted, sorry). A live install running gparted shows a totally empty disk!
The removed OS was booted via Grub2 and I imagine that it is choking when there is no secondary(?) file to be found since it was vaped. I also imagine that this is a fairly straight-forward matter, something like replacing the MBR but I am so far from Windows these days that I am unsure how to progress with rescuing the partition. The machine has no floppy - that's how I would have initially booted it way back when. Is this something that I can do either through a Linux live distro or via a Windows CD?
Unable to resize fedora 12 lvm parition with gparted. Need to resize to make room for ubuntu linux on same drive. When the fedora lvm parition is selected gparted says "No lvm support at this time". I am using gparted through the pmagic (partedmagic) linux boot disk. I have almost the lastest pmagic (5.7) there is a pmagic 5.8 on source forge.
This machine has UBUNTU & wINDOWS XP. I'm currently logged into UBUNTU. I was just checking the features of GParted and accidentally clicked Device > Create Partition Table. A default MS-DOS partition table is created. Now if I re-start the Gparted there is nothing. Its showing entire disk as UNALLOCATED space.
Lucky thing is All the drives (C:, D:, E:) are currently mounted and I'm in UBUNTU. I guess its possible to re-create the partition table using current status. how to do this. This is a lab computer. If its not recoverable. I'm completely screwed!
I removed an ntfs partition I had in my HD and then resized my home partition with gparted to occupy all the available space. The resulting partition is supposed to be 129GB, and gparted/partition magic see that size. But the system does not, and all tools report the old partition size and the same free space I had before resizing.
I have a 230GB hard drive wich I don't know it's name.I have a 207GB windows vista partition and the rest of it is for linux (Ubuntu).Today I decided giving it all space to Ubuntu Linux ,but didn't want to lose all my data from the windows partition.I thought that by deleting all things except the folder with my data and leaving enough space to shrink and make enough room for another partition to put my data folder.The logic is that i could then format that partition wich previously was windows and use it all for ubuntu without losing data.After having ubuntu installed i could copy my data folder to /home and then delete the previous partition and make /home bigger.The problem is that after i freed the space,when using Gparted to shrink it says that the partition has bad sectors or the filesystem has problems and so it can't do some operations.
What could have went wrong?It told me to do chkdisk but as i deleted all the windows files and i can't boot into it anymore.I used the vista dvd to do that.I rebooted 2 times as it says and after that when trying again nothing changed.I tried to use ntfsresize with the --bad-sectors argument and also the -f argument but it's useless.At the end it says it won't do anything until the ntfs filesystem get repaired.Or it says it is too risky to continueIs there any way i could do some superforce command to resize it without losing data?Please don't tell me to put it on an external storage cause i have like 70GB of datas to save...no i don't have an external hardrive
I'm installing Windows to update my BIOS. I've removed a previous partition but I can't merge free partition to my original partition containing data. How to solve this problem? I don't want to format the ext4 partition.
How can I access a Linux partition from Windows? How to read EXT2 from Windows 7 64-bit? Does a ext4 reader for Windows exist?
I am currently in Windows and was wondering if there is any way I could mount my Linux partition, so I can access and transfer files? The file system is ext4
I need a program that allows windows xp to read EXT4 partition. ext2explore.exe is not good, it doesn't give other windows applications direct access to ext4.
I need to examine a hard drive that came from another system running Ubunut Server (not sure what version). I know the drive has LVM on it, so as far as I understand that means the drive will be treated as EXT4 for mounting. I can't boot from the actual disk, but I have used a IDE to USB connector to make a binary copy of the drive, which I've mounted as a loopback device. However, when I try to mount the loopback device properly, I get this:
root@~je:/# mount -o ro -t ext4 /dev/loop0 /mnt mount: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
I tried using -t ext4dev too, but that just gives an unknown filesystem error. The file I've got mounting in /dev/loop0 is a .dd file, created by imaging the drive using dcfldd on the server drive while it was mounted (as /dev/sdb). System I'm working on is running Ubuntu 9.10. All I need is to be able to mount the server drive so I can traverse the file directories, there's a few things I need to check on it. If needed I can dispense with the whole loopback setup and just directly connect the server hard drive again using the IDE to USB cable, but I'd rather not do that; it's imperative that the drive doesn't get altered, or at least as little as possible.
i am trying to compile kernel 2.6.23 on Fedora 12 After fixing a few bugs (getline error, %dil ,etc) i was able to compile the kernel made initramfs img using dracut updated grub and then booted up the new kernel 2.6.23 but it fails to boot with following error mount: unknown filesystem type 'ext4'
I was reading another thread about someone with a bad partition table and I decided to join this forum. I'm not going to take any drastic actions with the partition (/dev/sda3) in question. I am going to wait for instructions on what to do first. I am not very good with Linux and need some hand holding. System: DELL 4550 Dual-Booted with XP and Ubuntu. Works OK, just no swap. Well, here's what I did: I deleted a partition for Windows XP Pro because it was a trial, and it ran out. I then decided to slide the swap partition for the Ubuntu Linux that I dual-boot into over. (If this was successful, I was going to try expanding the root partition to take up the unused space.) I used Gparted on a CD to do this, as I figured it was safe to do.
I now cannot mount the swap space at bootup (and have to go into a backup version of the OS), although I can use Gparted in Linux to execute the "swapon" command, and it appears that it worked because I now see "swapoff" as an option on the context menu. (I actually don't even need a swap partition, except to hibernate.) If I highlight the swap partition and click on "Drive" on Gparted's menu bar and select "Create Partition Table", it will erase all data on /dev/sda, so how do I fix the bad partition table non-destructively?
I usually repartition a disk by backing up, deleting the partitions, formatting them and repartition. I just did a 200 gig backup (so i am safe) and i want to join 2 (ext3) partition together, sdb1 (data4) and sdb5 (data5) into one big partition. Is there a way to do it without scraping the data in sdb5 (data5). It would save me from rewriting the data back to that new partition (200 gig is time consuming).
I didn't know a resize operation on a 750 GB disk was going to take 40+ hours, and I was biting my nails the whole time, until the power went out when "only" 8 hours where left.I can still mount the partition, and many of the files are still there, but some files show as '? ? ? ? ? filename.ext' with ls -l.If I try to go inside such a directory: Input/output error.
is 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.
My windows xp partition crashed for an unknown reason the other day and i was wondering if i could fix it from my mint debian partition. my windows partition starts to boot but then just hits a black screen and freezes and when i go to run it in any safe mode it just lists a bunch of drivers and then stops there.
