I am using Ubuntu since release 8.10, but it is first time when i can`t solve problem
when i tried to create new NTFS partition on unallocated disk space with Paragon Partition Manager (damn, that was stupid). Process was aborted with error (later i finally made it with Gparted without problems)
After reboot mine Ubuntu say:
Errors were found while checking the disk drive for /
Press F to attempt to fix errors, I to ignore, S to skip mounting or M for manual recovery. I pressed "F" but that had help only for a boot and doesn`t really fix error :`(
Later i booted from liveCD and had checked partition (/dev/sdb1; file system - ext3) with gparted (result - aborted fixing process with error) Now i can`t even boot from that partition and even mount it from other linux system.
I think that my external hard drive was either "unsafely removed" or powered off at a critical moment because when I tried to connect it to any OS Mac, Windows Ubuntu etc. It could not be read. I forget the Windows error message but the Ubuntu one was "mount error 2".In any case I downloaded testdisk asked it to analyze my hd and about half way through it said that the number of heads per cylinder were 128 and it more than likely should be 255 (or the other way around I forget which but I know the numbers are right). So I went and changed the geometry of the external HD such that the number is what testdisk told me was and the result is that my computers can read it but it seems that all the files are missing.
I used photorec and I have recovered all the files (unnamed and disorganized of course)So this leads me to the following question: is there any way I can repair my file system or access the files so that I don't have to go through the 16,000+ files rename and reorganize them again?
i have an external harddrive, hooked up by usb. /dev/sdb it came as a fat drive (sdb1). when i realized, i had copied 250 gb to it already. so, i made a new ext3 (sdb2) partition, copied the data from the fat to ext3, and then deleted the fat drive and moved the ext3 it with gparted. it mounted fine after it was moved, but after i tried to resize it, which didn't work, it will not mount.
I 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.
Recently I installed openSuSE 11.3 x64 on PC with Intel motherboard, 4GB RAM & two of 1TB WD RE3.Of course I set RAID1 during installation After some struggle with GRUB which pointed to wrong devices after installation I started to work. But suddenly I found that file system is corrupted after every reboot (It does not depend on what I use and what the way I use - reboot, shutdown -r now or even just poweroff - everything follow to:
Starting MD Raid mdadm: /dev/md2 has been started with two drives mdadm /dev/md3 has been started with 2 drives mdadm /dev/md4 has been started with 2 drives mdadm /dev/md5 has been started with 2 drives
I'm going to reformat my external drives to get rid of the crud that I've built up. (Crud being incremental backups, windows software, and similar things.)(I also want to get rid of the FAT32 file system that they use.) These are USB 1TB drives. The theory is that data is written to it once, but read back a number of times. (I also burn that data to DVD. If there was software that could organize 5TB of data on DVDs, I'd be using them.)
I"m trying to decide whether to use ReiserFS, Ext4, or another file system. Basically, I want something that:
* Won't get corrupted when the power fails; * Can handle files that are 4+GB in size; * Uses extends --- preferably without user intervention;
The Ext 4 file system of the partition (dev/sdb1) is corrupted. When I seek to repair this using the boot repair tool it is unable to resolve this. I admit that I don't fully understand the problem - except that I'm unable to open and use programs.
I need evaluate the ext3 file system performance; i need define:
- 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?
I accidentally formatted a HDD when I meant to format a USB thumb drive. The HDD is a 250GB drive that had about 180GB of data in the EXT3 format. I was actually attempting to make a bootable USB thumb drive with TRK (Trinity Rescue Kit). Kind of funny/ironic to mess up a drive while trying to make a rescue disk. Anyway, as soon as I realized what had happened, I pulled the drive out of the computer to make sure I didn't do anything else stupid to it. I have been searching for some way to recover and haven't really found much. There are a lot of programs to get Windows data back, but I haven't seen anything specific on the EXT3 file system.
I 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?
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 have an image of an ext3 file system done with dd. I know that the file system is corrupted but I want to try to recover some files. Whatever I dd it again to the original partition or assign the dd image to a loop device, that's what happens:
- dumpe2fs -h gives me a valid ext3 superblock.
- as I try to mount the device read only, it fails with a bad magic number error.
- executing dumpe2fs -h again gives bad magic number error.
- trying debugfs or fsck with backup superblocks fails the same way.
For me it seems that in spite of mounting the device as read-only, mount command do something wrong with the superblock as before the mount the superblock is correct and it's there.
I have configured a "Syslog" server on /var directory as a separate ext3 partition - to receive the logs and events from the clients & the firewall as well. The directory needs to grow dynamically as the logs are populated. Is there a way i can make the filesystem grow dynamically as and when the directory is full.
There were some files residing on my ext3 file system, using Ubuntu as my linux distribution. Yesterday I formatted the hard drive using a windows install CD, rewriting it with a new NTFS partition. I'm willing to restore my personal files deleted due to this format.
I have dual boot system..i.e, windows XP and ubuntu 9.10(insatlled side by side). when i try to boot ubuntu, Im gettin sh:grub > prompt
I am getting something like this.. root mount file system failed.. ext2 ext3 ext4 ....... kernel panic message and hanged at kenelthreadhelpper+ what can i do.. I cant reinstall ubuntu again.. Because I have installed nany application there..
i needed to change my external hard drive's file system from ext3 to fat32, to use it in windows, which i did the simple way: i shrunk the ext3 partition, made a fat32 partition, copied the files over, removed the ext3 and made the fat32 bigger. unfortunately, while gparted was making the partition larger, my computer shut down. i lost all my files and the partition messed up immediately. i made a new fat32 partition, after deleting the old one, but noticed that gparted was showing 100 gigs already in use (???). so now i have a 300 gb hard drive with only 200 gb i can use; i ran df to make sure gparted wasn't messing up, but indeed it shows the partition as being only 200 gigs in size. i haven't tried making any other kind of partition yet, such as ext3, for fear of losing my files again, and because it wouldn't be permanent anyway, because i need those files in windows and stupid microsoft won't make their OS ext3 compatible.
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 ?
I just rebuild the kernel for slackware 13, everything works, but root file system which is ext3 is mounted as ext2. Normally I've build ext3, ext4 and so on as modules, not in the kernel... but if I do this, then the kernel mounts the file system as ext2, which is build in the kernel. I also modified rc.modules so I can make sure that ext3,ext4,jbd are loaded, but it doesnt work.
