General :: Old File System Discovered After Disabling Ext4 Journaling

May 7, 2011

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:

Code:

/dev/sda1 ntfs ~100MB win boot,
/dev/sda2 ntfs ~170GB win main,
/dev/sda3 extended

[code]....

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.

General :: Journaling File System For HDD?

Apr 20, 2011

Is there a way to use JFFS2 (or other journaling file system) on an HDD? I'm looking for a file system feature that doesn't overwrite previously written data on an HDD.

Reason I'm asking is I'd like to use the capacity of the HDD as a log of all written activity, with the ability to retrieve old files. i.e. all writes to the HDD would be sequential.

General :: Instructions Work When Turning Of Journaling On An Ext4 SSD?

May 27, 2010

I have an Acer Aspire One with an SSD for storage. I recently installed Ubuntu on it and chose ext4 for my filesystem. Then I read that journaling on an SSD isn't the best idea, so I will try to disable journaling and I have found these intstructions [URL]..

# Create ext4 fs on /dev/sda10 disk mkfs.ext4 /dev/sda10 # Enable writeback mode. This mode will typically provide the best ext4 performance. tune2fs -o journal_data_writeback /dev/sda10

# Delete has_journal option
tune2fs -O ^has_journal /dev/sda10
# Required fsck
e2fsck -f /dev/sda10

[Code]...

I will use them on my boot partition. Are there any particularly bad parts here, or are there any missing steps? Will my boot partition be fit for being on an SSD after this? Or should I consider switching to ext2, or even reinstall it all and choose ext2 at partitioning time (I'd rather not though, since I've configured quite some stuff already)?

Ubuntu Security :: Wipe With Ex4 Journaling File System?

Feb 17, 2010

I was reading a website about securely wiping data from your hard drive with wipe on the right click menu, when I stumbled across part of the article where it talked about journaling filesystems.Article

Quote:

There are three types of journaling: journal, ordered and writeback. Using shred, with an ext3 file system presents the user with the problem of secure deletion because it can only really be effectively used with ordered and writeback journals. It also lists ext4 as a journaling file system in the article, so I looked up the wikipedia page on it and I also found this:

Delayed allocationExt4 uses a filesystem performance technique called allocate-on-flush, also known as delayed allocation. It consists of delaying block allocation until the data is going to be written to the disk, unlike some other file systems, which may allocate the necessary blocks before that step. This improves performance and reduces fragmentation by improving block allocation decisions based on the actual file size. So I am confused about this delayed allocation thing. My thoughts are that ext3 and other journaling filesystems are bad to use with secure wipe when they are set on journal mode because that writes the file to the journaling sector as well as to the hard drive. Apparently, in ext3, the default was ordered mode. I would like to know if anyone has any idea if the ext4 file system on karmic 64bit is hazardous to the security of using the wipe command.

Ubuntu Security :: Delete Files Off Journaling File-system?

Feb 19, 2010

I have some very confidental files on my computer that I store such as credit reports, and other things. I always encrypt them with GPG, but there still is that original non-encrypted file left that needs to be deleted. I looked into tools like wipe, and shred but they all say that it really doesn't help on journaling filesystems directly on their man page.

I am not asking how to wipe the whole drive with dd or anything, but I am simply asking if there is a tool that'll delete a single file securely.

General :: Stuck Choosing Between Ext4 And Ext3 For The File System?

Jul 7, 2011

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?

General :: Recover Files From Ext4 File System Overwritten By New Installation

Jul 3, 2011

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.

General :: Ext4 New File System Mounting Compatibility With The Older Ext3 Type?

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 ?

Ubuntu :: Ext4 File System Hosed After 11 Upgrade (duplicate Directory & File Names)?

May 8, 2011

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:

Desktop/
Desktop/
Documents/
Documents/
Downloads/
Downloads/

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:

Ubuntu :: Ext4 File System ?

Aug 6, 2010

I'm trying to figure out why files in linux are oriented in the folders the way they are. In Windows it's much simpler to picture. You have program files (C:Program Files(x86), system files (C:Windows), user settings for programs or personal stuff(C:User), and some weird folder names. I was noticing that the Ubuntu ext4 filesystem is a little more complicated. Some folder names are self explanatory, but others are not. Is there a guide, or some reading material on the history of the linux filesystem and how it morphed into what is presently used in Ubuntu?

Ubuntu :: Edit File Discovered It Didn't Exist - Configure Grub?

I have recently installed Ubuntu Karmic on my laptop, which also has Windows 7. It now has GRUB, and I have been able to modify some settings via the GRUB command line. However, these changes are not permanent; they are reset the next time I load GRUB. I have seen many people trying to configure GRUB who have been pointed towards /boot/grub/menu.lst. I expect it would) I went to edit that file... and discovered that it did not exist. I am certain that I am using GRUB, not some other bootloader. Is there another possible way to configure GRUB, or somewhere else I might look for this file?

OpenSUSE Install :: Mounting Or Checking A Partial Ext4 File System?

Sep 3, 2011

If you have a contiguous partial piece of an ext4 file system (assuming it's perfectly clean), starting from the beginning of the partition, is there any way to check it, or to mount it to get the files whose parents, inodes and data are all completely contained inside?

Have (or maybe had) a very large 11TB RAID 6 array, filled with a single large ext4 partition. Something strange happened when a single drive failed and the array ended up failing 13 out of the 11 drives. I had trouble getting the array restarted, and got to the point where I exhausted all of the options I considered completely safe. I considered a few things that may have worked, but mdadm doesn't seem to have a definite "do not change anything" option. So I decided the only way to be absolutely safe would be to clone the disks before proceeding - then I realized how much time that would take and sent the drives off to a recovery service so they could image them and check it out.

Before doing so, I copied the first 2GB from each disk. I XORd the images from the working drives to reconstruct the data chunks that were on the failed disk, manually assembled the chunks, and am very confident that I have 22GB of "correct" data in a single file. The parity and Q syndromes all matched (with RAID 6 you can still check with only 1 missing device). I've learned the fine details of ext4 from [URL], and have looked at lots of raw data from the reconstructed partition, and it all looks good. The recovery company says that they're not finding many inodes, but I found a lot of them, exactly where they're supposed to be. I tried to mount and e2fsk, but both processes seem to be extremely unhappy that the device size doesn't match the size implied by the file system geometry.

I considered hacking the superblock to manually reduce the size, but I figure that wouldn't work because there would then be more group descriptor blocks than it would expect after the superblocks. I might try doing that and compensating by incrementing the "reserve block count" to compensate. Alternatively, if there is some way to make the file appear to be the expected size with nothing but zeroes after the end of the actual data, maybe I could mount it and not get any errors until I cause the kernel to read past the true end of the file.

Ubuntu Installation :: The Ext4 File System Creation In Partition Failed?

Feb 11, 2011

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.
