Software :: Most Lightweight Non-Journaling Filesystem
Jul 6, 2011
I am trying to install debian on a slow netbook, and I can only install to a bootable SD card. The SD card is 200x, so it should be fairly fast. I was just wondering what filesystem would be the fastest, and use the least amount of cpu. I think it should be a non-journaling one, since this is flash media. I was thinking ext2 originally, but I heard ext4 has a non-journaling option, and is faster. However does ext4 take up more cpu usage?
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.
Does anyone know of any high-quality journaling software out there for F12KDE? I tried Keepnote, but it is not installing properly. Needs a Python(abi) dependency.
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
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)?
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.
I use Slackware64 -current. I will buy a SSD drive, normaly the filesystem in my laptop is EXT4. Is there anything that I need to know? How to improve life of the SSD? Is journaling a good option? How to disable?
I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage *Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?
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.
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.
I recently tried to install Ubuntu on an old disused laptop I inherited. I bought a new hard disk just for the purpose. Unfortunately it crashes when trying to install Ubuntu/Xubuntu/Mint. Long story short, not enough RAM and an old processor are the cause. I was wondering if there are any very lightweight OS out there for old computers. I realize it depends on what I want to use the laptop for. But I dont know what I want to use it for until it is usable. SO I'm just looking for anything. I found this linux distro : [URL]..
I was running it portable on a 4gb usb drive via virtual box which worked great unless I used a computer that had virtualbox on it. The portable version would remove files that the original version needed. I decided to try Qemu. The problem is that the portable version only allows 1gb of space to install regardless the size of a usb drive. so the question is: Is there was a way to trim ubuntu 9.10 down to less than 1gb of disk space? If not is there another portable emulator that could be used instead? the only uses for this are for the use of evolution and opera in a linux environment.
My issue is that I have a small VPS (512MB, 1024 burstable RAM) and I am planning on using it as an application server for say a voice server and maybe a small game server.
Coming from a Windows background, the only way I know to do this is to have a GUI + Remote Desktop and download + install the servers and run them as one normally would on a desktop PC.
But obviously this would eat up a considerable amount of my RAM.
Is there a way to download and run something like Teamspeak 3 just through the kernal alone?
If possible, is it worth the hassle (especially if I am running multiple server applications)? Or am I better off using a desktop environment + Remote Desktop?
With gnome-do, you can do things as quickly as possible (but no quicker). In a low-spec application, the 'do uses up ~16mb of ram even in idle mode, if I recall correctly. Are there any lighter alternatives to gnome-do? It's so useful - but I feel like its functionality could be even snappier.
I have a problem with my old pc the hardware : RAM: 192 mo . HDD: 120 GB (no probelem here). CPU: 600 mhz. Card graphic: 8 mo. The problem that I need a dstro can run using these requirement but distro must be provided by the (wubi).
My Hard Drive in my PC went poo poo, so until I get a new one, I am going to be running off of a live cd for a while. What is a good small distro that is lightweight enough to be used on a Pentium 4 and 512mb of ram?
I was reading about ext3 feature and I have read about its journaling modes. I would like to ask what is the default journaling mode of ext3 fs in slackware(or is it in all distro using ext3)? I'll install slackware when my new pc arrive and the fs I will use will be ext3 and I like it to have data=journal mode for its journaling. I have read in some wiki how to set the journaling mode into data=journal mode.
Code: # tune2fs -O has_journal -o journal_data /dev/sdXY Do i need to issue this command or is this the default mode in ext3 in slackware?
One one my criteria for client machines is the ability "just work" from a generic business standpoint. By this, I mean any user needs the ability to drop in a jump drive or download that contains MS office formatted stuff, work with it, and save it in the same billie friendly format.
That means OOFFICE, right now. Which NEEDS the GTK libs (I confess I have heard of a QT version, but it's the same dilemma, really)
So, why do I bother with Openbox, XFCE, LXDE, E1[6-7], Blackbox, Fluxbox, etc? All the bloat I'm saving on WMs is rendered superfluous by the monsterbig GTK+ libs for the office suite Why not just give up and run a stripped gnome core?
This is really an open rant, but I'd love to hear if anybody has addressed this problem successfully. I guess I'm craving an opensource suite with Office's power and no bloat (I'd also love to meet st. nicholas, the easter bunny, and that guy who smokes marlboros in 'the x files')
Adobe Reader is the best, but it's so resource heavy. It takes almost 10% of my 8GB ram. Evince has trouble with highlighting text and does not support tabs. Foxit Reader for Linux does not support tabs. Any assistance in choosing an appropriate PDF viewer that supports these features on Linux and isn't too resource intensive?
I'm currently installing Arch Linux on my old netbook. What desktop environment should I use? GNOME and KDE both seem way too big and unnecessarily fancy for what I want to do with my basic netbook. I just want internet, read pdfs, run emacs. no fancy stuff. What should I use? xfce? lxde? and why?
Uzbl uses hjkl for moving around, much like vim does. I was wondering if there was a browser (text based like links, or needing X like uzbl) which would be easy for someone used to emacs key bindings?Or if there is an emacs mode for having a buffer behave like a Links browser, but with emacs keybindings to move around...[For linux systems, please ideally something available through AUR or a debian package or both]
I need such a OS on a old system for mass downloading and experimenting downstairs. Also I would prefer if it doesn't require too much Linux know-how and is operable by my Windows 7 system via networking. It doesn't need to be compatible with TrueCrypt or JDownloader specifically if alternative software for it exists.
For a while I have been searching for a new desktop environment to use on my netbook, since gnome 3 is too heavy for it. Currently it is running ubuntu because unity is lighter than gnome 3, but I am planning to go back to fedora at some point in time. So far I found LXDE to be my favorite, after trying XFCE and Enlightenment.I'm not looking for a solution here, just opinions, what is your favorite lightweight desktop environment (and with which WM if you wish) and why?
For coding under X11, I am looking for an a lightweight alternative to GEDIT with 2 Panels + GTK? left is the all the files into a given folder right is the notepad
When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.
I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.
After installing UNR, I found the unity interface to be lacking advanced features, support on forums and tweaks. So I installed the ubuntu desktop, but I kept maximus (and tweaked the list of apps which shouldn't be maximized, so I am pretty happy with maximus). Since netbooks aren't as fast, I wanted to get a more lightweight desktop environment. I started with replacing Metacity with Openbox (since it seems to be quite popular). I noticed that after logging in my memory usage was 186 MB and 189 MB after running ubuntu tweak, for both window managers. If Openbox would be as lightweight as it claims to be I find it rather strange that I don't notice any difference in memory usage. (about my "test": I changed the default window manager using ubuntu tweak, logged out and logged back in to start a new session, opened system monitor to measure memory usage)
