Fedora :: Formatted EXT3 Partition - Recover Lost Data?
Jan 26, 2011By mistake I formatted an ext3 partition on my external hard-drive. Now it has turned into a vfat filesystem. Is their any chance of recovering the lost data?

Nov 13, 2010Yesterday I ran an extremely dangerous command by mistake:
Acctually I intended to dump the iso to a usb disk. Soon I found the "of" is incorrect, but 1 second has passed...
Since everything happens in 1 second, only MBR and /dev/sda1 has been affected. The filesystem of sda1 is ext3.
So, can I get any luck trying to recover data from the broken partition?
General :: Recover Data From Ext3 Partition?
Dec 30, 2009A HP Netserver LP2000r, with original SCSI controller and HP NetRaid-2M controller, 3x 36GB Ultra3 HDD in RAID5, Debian (sarge/etch), has crashed after 992 days without reboot. From all that I can see, a hardware failure, most likely with the memory. The HP Diagnostic tools cannot find any problem, but everytime I boot into Knoppix, I get between 2minutes and 2 hours of runtime, and then either a kernel oops or just a complete and sudden halt.
Well, the box has earned its money. However, there is some data on the drives that I need to recover (yes, I have beaten myself up properly about not backing up that data, don't even go there !). There are three partitions: sda1 is /, sda2 is swap and sda3 is a LVM volume with 3 logical volumes on it. As far as I can tell, the hardware defect must have been creeping in and has made a total mess of the inodes in all these partitions.
After booting into Knoppix, I can restore the volumes using pvscan, vgscan, lvscan, vgcfgrestore and vgchange. If I try and mount them: mayhem. So I try and check them, using fsck.ext3. All sorts of interesting nonsense, such as a completely empty inode 11 (the first inode) and then obviously from there on all else is pointless. I tried using debugfs, but the information on what to do with it is somewhat spurious.
P.S.: Tomorrow I will go and get myself a 16GB Flash Drive and then hopefully I will be able to dump the partitions one by one onto that drive and transfer the images onto a different computer for analysis and data recovery.
General :: Recover Deleted Directory In EXT3?
Jul 19, 2011recover deleted files using "debugfs" & "extundelete" by running:Code:sudo debugfs /dev/sda3
and find inode number of deleted file using "ls -d" command and then running:Code:sudo extundelete /dev/sda3 --restore-file <inode#>but when my desired file was in a deleted folder I can't find my desired file inode number using debugfs
Software :: Recover Lost Files Under Ext3?
Mar 12, 2009Now am terribly frustrated because i reinstalled my linux installation(Ubuntu 8.04) after falling prey to an inode error. So i reinstalled stuff under my root partition under which i had some files which i obviously lost.I have tried recovering the files (mostly mp3 files) using photorec and the max file size i managed to recover was 4.0MB. the rest fall in the tune of 300kb.My question is, is there a way to make a full recovery of the above files seeing that they indeed can be recovered?
View 1 Replies View RelatedHardware :: Recover Data On Ext3 Partition On Ubuntu?
Apr 25, 2009I wanted to upgrade from Intrepid to Jaunty. I opted for a format/reinstall as I figured upgrading usually sucks. To save my important data, I resized my partition (partition A), formatted the empty space with ext3 (now partition B), and moved the necessary files from partition A to partition B. Then I went through the install process and installed Jaunty on partition A, telling the installer to NOT format partition B. It gave a warning about the installer deleting system folders (var, usr, etc) but I figured it didn't apply. I was wrong.
So now partition B is "empty." I know it didn't format it, but I need to get those files off of there. I have created an image of partition B using ddrescue, but I don't know where to go from there. I tried using foremost, but it won't recover things like my virtual machines and completely nukes the original file structure I had. And I've tried mounting it (using sudo mount -t ext3 -o loop /home/user/recovery.img /mnt), but that doesn't seem to work. The mount command completes successfully, but nothing shows up in the folder I mounted it to.
General :: Recover Data From Ext3 File System?
Jun 20, 2009I have accidentally removed vmware virtual disk, my host operating system is RHEL5.2 with ext3 file system, i have used photorec, magicresue and foremost but still no luck to recover the vmdk file. i have seen in foremost configuration file that there are some predefined files (ex- doc, pdf, jpg, avi, zip, etc),
1. is there any way to add vmdk file extension on that configuration file?
2. if yes how can i do ?
3. by adding vmdk on configuration file, can i specifically use recover option for vmdk?

CentOS 5 :: Unable To Recover Deleted Files From Ext3 Partition?
Feb 10, 2011I am using CentOS 5.5.I suppose this is an oft repeated question. I accidentally deleted, using rm command, 2 wmv files. The files were in a single ext3 1Tb drive, with just 1 partition --- the ext3 one. Each file is 600 - 800mb. The 1Tb drive has only about 20Gb data.Immediately after deleting the files i unmounted the drive (/dev/sdc1). Thereafter i searched the the net and came to know of the recovery tools foremost and photorec. I have installed both of them. I am currently running both of them as root --- foremost is just showing a lot of * signs on the terminal and photorec has managed to find some txt and png files --- but no wmv.For foremost i used: /usr/sbin/foremost -t wmv -i /dev/sdc1For photorec i followed some instructions available on the web.
In the meantime, based on some post on the net i ran debugfs as root, then cd into the directory where the files were deleted. Then on typing ls -d i managed to get the inodes of the 2 deleted files and the names of the deleted files are also correct. The instructions on the net http://www.theavidcoder.com/?p=3 tell me to run fsstat and dls both of which i am unable to find in /bin, /usr/bin, /usr/sbin and /sbin. So i am unable to proceed further.
General :: Recover Data From Encrypted Partition (created By EXT3 Ubuntu 10.04)?
Oct 11, 2010I am facing a serious problem.I installed UBUNTU 10.04 and encrypted it during installation. I accidentally erased some of the necessary files from root folder. now the the OS is NOT booting.luckily i still have the encryption key i have some important documents in that drive (desktop folder).
PS: I have tried to run Live Ubuntu it shows the Root, but it does not enter any of the folder.
General :: Recover A Deleted File Using The Ext3 File System?
Jan 10, 2011I used the ext3 format when I formatted my partition prior to installing Ubuntu10.10. I had accidentally deleted a file and began the process to get it back. It wasn't critical but helpful to recover the file. To make a long story short I ran into to some unexpected road blocks. I tried to use PhotoRec to get the job done but with no success.
I'm just looking down the road in the event I might have to recover something important.If it would be better going back to the Fat32 file system I would rather do it sooner than later. Just as a side note I am dual booting between linux and windows.
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.

Red Hat / Fedora :: How To Mount EXT3 Partition
Jan 20, 2010I just made a new storage partition and formatted it as Ext3. Now, this particular partition is shown and can be read at the terminal "fdisk -l". However, unlike in my Mint 7 partition, it does not show in my Fedora 10.
Code: [jun@localhost ~]$ sudo fdisk -l
[sudo] password for jun:
Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xc5e3f820
[Code]....
This partition can also shows be seen in gparted in Fedora. However, even in the "Places" tab, it does not show.

View 1 Replies View RelatedFedora :: USB Automount On GNOME - Ext3 Drive
Nov 26, 2009I have two USB drives, one with ext3, and the other w/vfat. On my new Fedora 12 installation, GNOME properly automounts the vfat drive on insertion. However, it applies a wrong command to mount the ext3 one. The end result is that the ext3 drive appears in /etc/mtab but, unlike vfat, is inaccessible to non-power user.
The mtab is: /dev/sdb1 /media/918fb656-8efc-43b5-bdfd-0bd8004deeba ext3 rw,nosuid,nodev,uhelper=devkit 0 0
/dev/sdb1 /media/49C6-1901 vfat rw,nosuid,nodev,uhelper=devkit,uid=500,gid=500,sho rtname=mixed,dmask=0077,utf8=1,flush 0 0
Somehow GNOME misses the uid=500,gid=500,shortname=mixed,dmask=0077,utf8=1, flush portion of the mount command when mounting the ext3 drive.
Fedora Installation :: 11 - Error - Unable To Use EXT3 Or 4
Dec 10, 2009I am trying to install Fedora 11 in Virtual Box using the Live CD. When I try to format with EXT4 (Default) it says the boot volume cannot be EXT4, when I try EXT3 it says it doesn't match the Live filesystem. This is retarded it won't let me use either. (I don't usually throw around the word retarded, only in rare cases and this is one)
View 3 Replies View RelatedFedora :: Maximum Number Of Files In Ext3 ?
May 26, 2010Is there a limit to the number of files ext3 can support?
Reason I'm asking is because on one of my internal drives, I have around 750,000 files. The drive is 500Gb and currently using 150Gb... I noticed recently that when I try to copy a new directory or file, the transfer rate is extremely slow at times. It is sataII and sometimes it gets as low as 500kb/s (yes, kb!)
Would somebody please shed some light?
I noticed it might be related to the process gvfsd-metadata
I'm using Fedora 12 64-bit
The transfer is from an ext3 to ext3 filesystem.

- services provided
- parameters and
- the performance with different parameter values; for example, changin the value of the "data" parameter (journal, ordered, writeback).
I do not know what services ext3 provides. Well, i know intuitively that it provides services to read, write and erase files. But, there are anything more?. Where can i find the API?. Is the ext3 file system POSIX compliant?
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.

View 2 Replies View RelatedFedora Installation :: 'Upgrade' Filesystem Ext3 To Ext4 While Upgrading ?
Jun 11, 2009Is that possible, I mean when I upgrade F10 to F11 with yum upgrade is there a way to 'upgrade' the filesystem to ext4 for example (with the exception of boot partition)? Or I have to reinstall fedora like new?
While changing the filesystem can I do it by parts? what I mean is for example: I have 2 partitions like '/' and '/home' with ext3, so I backup data in '/home', change '/' to ext4 then mv files from '/home' to '/' and change '/home' to ext4 and finally mv those files from '/' to '/home'. Is that possible?
Fedora Installation :: 11 - Can't Be Mounted When Booting After Converting From Ext3 To Ext4
Jun 16, 2009I upgraded F10 to F11 successfully.
Then I convert the / partition filesystem by the following steps:login as root user in multi user mode read [url], and execute tune2fs -O extents,uninit_bg,dir_index /dev/mapper/VolGroup01-LogVol00 modify /etc/fstab, change the type of / to ext4
reboot
(because fsck say running it on a mounted filesystem can cause filesystem damage, so i decide to reboot to single user mode first. maybe it's a mistake here) try to boot F11 to single user mode, failed
reboot from a SystemRescueCD-1.2.0 LiveCD
run e2fsck -fpDC0 /dev/mapper/VolGroup01-LogVol00 in SystemRescueCD-1.2.0 LiveCD, no error reported
reboot
try to boot F11 normally(multi user mode), but it failed at: EXT3-fs: dm-0: couldn't mount because of unsupported optional features (40).
I tried rescue mode of Fedora-11-i386-netinst.iso after these steps above. The / partition can be found and mounted to /mnt/sysimage correctly. I can read/write files in / partition, and i can even yum new softwares in rescue mode, but it just can't be mounted when booting.
