General :: Shrinking Broke Partition Table - EXT4 File System?
Aug 23, 2010
In an attempt to shrink my Data partition on my 500GB drive I had succeded in shrinking it but I think I have broken the partition table as now it refuses to mount. When trying to mount I get this error mount: wrong fs type, bad option, bad superblock on /dev/sda2 I have done some searching around but most fixes haven't worked because they are based on ext2/3 File systems and this partition is ext4. Using Ubuntu 10.04 x64.
I have tried to automate the configuration of a usb drive with not much success.
The problem that I have is that I have a large amount of usb drives that have a partition table of type "loop" and I need to change them to "msdos". The size of the drives vary and I need to use FAT32 or FAT16 file system.
I've tried various partitioning commands and gui applications but cant find one that I can give a one line command to to set the partition table, maximum partition size and file system.
I have nearly 200GB of space free on the HD with my linux main EXT4 partition, and I'm wondering if I can convert a large part of this to a new NTFS partition that I can use for my windows XP paralell install?
Basically, what do I have to do to resize and create the new partition and how do I get windows to recognize it?
I have a Dell Mini 9 netbook. The SSD took a dump, so I ordered a Super Talent 16gb replacement. I put it in yesterday, tried to install 10.10 and constantly get errors. The first error, which I haven't had since, was [ERROR 30] Read-only File System. The install obviously failed. Wondering if perhaps the file got messed up in translation, I redownloaded 10.10, reformatted the flash drive (sandisk cruizer 4gb), put 10.10 back on via the program on the Ubuntu site. No luck, but no longer the [error 30]. Tried again using Unetbootin, no luck. Rinse repeat a few times, no errors just a working cursor spinning and spinning and spinning and spinning and.. you get it.
Tried to put WinXP on it just because I was that frustrated, no luck.
Now I'm back to Ubuntu (because let's face it, who wants to deal with Windows, christ they make it so complicated). I'm currently using 10.04 because I was hoping (praying) it might just be a 10.10 thing.
No such luck, now it goes to step 7/7, starts, and 5% of the way thry "creating ext4 file system" it says "the ext4 file system creation in partition #1 (0,0,0)(sda) failed." I have checked the SSD in the Disk Utility, SMART tests are clean. I have gone to terminal and run fdisk and had a smarter person than me look at the copypasta, no errors, I have deleted all existing partitions in gparted and started fresh. I have tried the auto partitioning, I have tried manual, I am going insane. Literally insane. My preschooler thinks I've leaped off the deep end.
Could it be my flash drive? Could the SSD be defective despite the tests coming back clean? What do I need to type into terminal? Is there a way to entirely entirely entirely wipe the SSD to make it fresh-out-the-box clean? I will happily provide whatever you need if it means I can get my husband off my back about this stupid netbook with its stupid tiny keyboard.
I downloaded the ISO from the Ubuntu site. I can run it from the CD without any problems however, when I install it, it freezes. I am installing on a 2nd hard drive in my computer. It gets up to the point of "Creating ext4 file system for / in partition #1 of SCSI1 (0,1,0)(sdb)... I've tried deleting the partition and creating one by myself with no prevail. I am going to school for computer networking and my counselor told me that it'd be a good idea to learn the Linux OS for my major.
I can't seem to get past step 6 of he installation of Ubuntu 10.04. I get the error: The ext4 file system creation failed... on single partition (no raid). I chose ' / ' as the mount point, and have tried with and without a swap drive. I'm installing on a Sony VAIO VGN-NS160D, and the HDD was previously formatted to NTFS. There's no other OS so I don't see any way of getting a command line to try a sudo fdisk..
I grabbed the new lubuntu 10.10 from [URL] but it turns out I'm having a problem installing it on my netbook (Asus Eee PC 1015PED). While installing, this error pops up:
Quote:
The attempt to mount a file system with type ext4 in SCSI2 (0,0,0), partition #1 (sda) at / failed.You may resume partitioning from the partitioning menu.I'm installing via USB and have selected the option to erase everything and use the full HDD.
Unable to install Ubuntu 9.10 on a new internal harddrive. The hardrive contains no operating system. This hardrive is the only drive present in the system.
Whenever the installation trys to mount the ext4 partition the following error appears: The attempt to mount a file system with type ext4 in SCSI1 (0,0,0), partition #1 (sda) at /failed
Iv'e tried over and over to get past this error to no avail.
I accidentially overwrote the first 1M of my harddisk on linux (using dd). So, the partition-table is gone. I can still access all partition (except the first one) using /dev/sda2 (and so on), so the data is still there. I only need the partition boundaries to restore the table. How can I do this? The Linux-Kernel must still know them because all mount-points still work. fdisk -l /dev/sda doesn't work because it acctualy reads the partition table.
I am a new user of Linux, and I actually had a task that is the ability to resize (specifically Shrink) storage of Virtual Machine, I was thinking that the best to start on is to know how to resize partition in linux using command line since our VM runs in Linux environment.
I have serwer Debian with my website. My provider splited the disc into 5GB partition for / and 495GB partition for /var. Everything was going ok for over two years but now I don't have enough memory on /. I'd like to increase the partition but the problem is that /var is just next to it so I can't easily change the end of the first one. I need some safe solution. It might be even just shrinking partition for /var, adding new one after if it helps anyhow (I have about 450GB free memory).

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?
I bought a ssd drive for my laptop, installed it, installed Windows 7, installed Kubuntu 11.04. Till then everything worked fine, and I had following partitions on my disc:
It worked fine. While using 11.04 I encountered a serious bug in nvidia 270.41.06, and decided to switch to Kubuntu 10.10. I installed 10.10 on the very same /dev/sda5 (clicking a checkbox to format it). Everything worked fine, grub was installed and pointing to win7, and kubuntu 10.10. I disabled ext4 journaling as above, rebooted, and found, that grub now points to win7 and 11.04, and that system (which should have been removed during installation of 10.10) loads perfectly fine. I checked where 11.04 had been installed - still /dev/sda5. Win7 loads fine as well, so no linux on /dev/sda2 I checked if there was 10.10 kernel in /boot - no. File system on sda5 had no trace of 10.10.
I formatted sda5 with gparted, installed 10.10 again, disabled journaling and situation repeated, whole file system on sda5 changed. Enabling journaling did nothing, 10.10 didn't come back. I deleted sda3, sda5, sda6, made them again, installed 10.10, disabled journaling, and finally had my 10.10 on ext4 without journaling. So this is kind of solved, but I would still like to know that the hell happend? For the moment it looked like two file systems coexistened on one partition.
Is there a difference between using GPT partition table when formating hard drives and MS-DOS partition table? What are the advantages/disadvantages of using either?
My main hard disk died and I replaced it. After installing windows in a small partition in /dev/sda, I thought I will try linux mint and went for it. (I need windows to play AOE, but ubuntu is my primary OS)I didnt see the options properly or some distraction, I choose the "install alongside windows" option probably expecting it to install it in the unallocated partition next to the windows installation. I had completely forgotten my second internal drive /dev/sdb which has the backup data. Linux mint went and installed itself on that drive.
Is there a way to recover individual files from the second harddrive. Now if I boot or open it through live cd, all I see in the linux mint file systems. I want to aleast recover my CV/resume from the second drive. The second drive is a single ext4 file system The old drive is completely dead, it doesnt even get recognized when I attach it to SATA.
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 ?
When I start up the thing says "The symbol 'rtoul' not found. Aborting", then it ether boots from a CD, or beeps offensively at me.

I have a GRUB backup pen drive thing, but when I boot from it, it wont accept any keys other than CTRL+ALT+DEL. The partitions can be mounted and are usable, but home is encrypted. I don't want to delete my files.
I was trying to perform a new install, so sensibly made a back-up of my data to my external drive. Unsensibly, I didn't unplug the disc before starting the install and the install trashed the partition table/FAT on the external drive.I've used disktree and can "see" that the disk has lots on it, but I cannot access it.
I need to be able to access the files on the image of a hard drive created with ddrescue. The original drive had bad, unreadable sectors, and was corrupted in a way that damaged the partition table. It was formatted NTFS, but because of the corrupted partition table, nothing recognizes it as such anymore. Is there some other way I can mount it, rebuild the partition table or create a RAW file tree out of the image file?
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:
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:
USB flash disk partition disappeared as well as partition table I'm not sure about the cause
Code:
root@u# less /var/log/syslog usb 5-1: New USB device found, idVendor=058f, idProduct=1234 usb 5-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[code]....
Where did the partition table go? The device had one ext3 partition something around 4GB(size of USB storage device). I need to restore few files from this device.
I have one computer with windows and one with ubuntu. I have an external drive (FAT32) with files taken from an NTFS (mp3s and such) and I would like to put them and use them on an ext4 ubuntu platform. Can I make a partition of the /home folder NTFS and the system ext4 and function properly? I do have configuration files in the /home folder since Im building a domain controller that utilizes samba on ubuntu: would I be better off using a dual boot with windows/ubuntu and placing the files on the Windows partition? what is my best option?>
Can windows read files from a home file server with an ext4 file system? or do I have to partition the drive with the server (ext4) and an ntfs partition with the files on?
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 recently decided to resize a partition on my HDD (partition on which Ubuntu was previously installed).This was in order to remove Ubuntu from one of my HDD. I got rid of the Grub loader by booting on my windows system recovery disk and using Bootrec.exe/FixMbr and my computer now boots directly into windows. I then deleted the Ubuntu partition.
To get to the heart of the problem, I am trying to move the free space that is in the extended partition out and merge it with C. I tried doing this with my Gparted liveCD but it didn't work. I didnt have anything to save the error message onto, but I will try the process again when I get home and save the error onto my external drive so that I can post it here.
I'm trying to define the partition table type (I want to set it to msdos) for an automatic installation using preseeding file. (Why? I want to setup a software RAID 1 with two 2TB disks, by default the installer uses gpt partition tabless on those disks, where it's tricky to install grub(2), as there is no mbr, and the root partition is on a md device) During manual installtion it is possible to set the partition table type (by setting debconf priority to low).
[Code]...
Does anyone know what I have to put in my config file so that a msdos partition table will be created Also any other solution is welcome. I just want to have my root partition on a raid 1 and have grub installed, so that it boots up (No other OS is installed on the boxes. Debian squeeze is used)
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
