General :: File Fragmentation Under Ext Filesystem?
Aug 11, 2011I heard that the ext file system does not causes file fragmentation. Could some one explain how this is achieved. And how come a file does not divides in to fragments as compared to Windows based Filesystems.

Apr 21, 2010I have millions of small chunks of new's and delete's in my program. Even though no memory leak is detected through valgrind or purify, memory grows. But the growth is degrading over the number of times of the execution of the tasks. Can i think that fragmentation plays a role in this?
View 6 Replies View RelatedOpenSUSE Install :: Losing Valuable Internal HD Data
Apr 1, 2011to start: I am a 100% linux virgin. I have yet to boot once. I have a 1TB external HD bought today (), which I formatted to 32GB Fat32 and the rest NTFS. (The 32GB partition is the second in order) I tried installing 11.4 with the full release DVD, and managed to get through the 'partition' part of the setup without raging about losing valuable internal HD data. I changed / to the 32GB partition, and figured a native format was safer: formatted it in setup as Ext4, and installed after ignoring the under 128GB warning (the machine is only a few months old).
The installation seemed to go well. The loadup was unsuccessful. There were plenty of "fails". I was given a command screen with "Login:" and after, "Password:". It seemed to take the Login, however the correct password echoed back a "Login module failed" or something similar. Interestingly, an incorrect password yielded a "Incorrect Login". What I may need to do (?):
1. I did not specify a /home or swap during install
2. ?
3. ?
etc
Ubuntu :: How To Ext Fragmentation Resistant
Apr 24, 2010I told my friend ext3 and ext4 are very fragmentation resistant compared to ntfs and he questioned me as to what happens if a small file was removed from in between other file chunks and then another (larger) file was to be written and it wouldn't fit there; where would it go? His argument was that the ext filesystem does need to defragment in order to get past that and his argument seems logical. Does anyone know the answer to this? (because it actually captured my curiosity)

View 3 Replies View RelatedFedora :: Writing To NTFS Causes Fragmentation / Solve This?
Aug 26, 2010For some reason when i write a file to my NTFS-partitioned external HDD the files seem to get severely partitioned. This only happens when writing to it from within Fedora.
Windows Vista doesn't seem to do this.
This image is a screenshot from MyDefrag.
On my other hard drive i have a 7GB file consisting of 1400 fragments.
i'm guessing this is too much fragmented, because it was a completely empty hard drive before it wrote the file.
What could have caused this please? and how can i solve this?
Ubuntu :: Ext3 Anti-fragmentation - Does Not Provide The Extents Feature Of Ext4
Jan 6, 2010I work with lots of big files >500MB. As ext3 does not provide the extents feature of ext4, I am concerned that some fragmentation may periodically affect disk performance. Noted I understand that using ext4 under these circumstances would be pointless, because the extents feature would be required to be disabled to allow compatibility using ext2fsd at this time, thereby removing any tangible ext4 benefit for my purposes.
Question Would an effective method of disk optimisation and anti-fragmentation be to simply copy all files from the ext3 media partition across to another entirely separate empty backup ext3 drive, before copying them all back over to the ext3 media partition again? Would this mean that when all the files are copied back again, they would be placed back in the 'correct and optimum order', so to speak? PS: I cringe in advance at the n00bs who are likely to reply to this thread with 'ext3 cannot become fragmented'!

Oct 7, 2010I'm using Xterm. While running a prog/command if I scroll up and reading something on the screen, the xterm view resets to bottom if there is some output from the running command.
I tried enabling/disabling jump scroll, asynchronous scroll, scroll to bottom on tty output options of Xterm with no avail. In one way or the other way, the screen is scrolling or resetting to bottom if there is some output to screen.
I want to stop this behavior and the scroll should work as if it is in Konsole. The new output to screen should simply add at the bottom and the current viewing point should remain unscrolled. pls let me know if there is any working solution for this xterm problem.
General :: Avoid Logging With Root User?
Jul 22, 2010I have created a linux machine and installed some softwares on it with root user privileges . I used to login with root user credentials for doing the various task.
Later i have realise that this is not the best practice to follow and there should be a new user with less privileges to be created for doing the day to day task.
I have read the steps to create the user but will that new user sufficient enough to do the task that i m doing it through root user?
Will my software allow the new user to work on them?
I would be glad if someone points me to a guidelines on what should be my next step?

View 2 Replies View RelatedGeneral :: Set Up User Account To Avoid Giving Much Power?
Jul 30, 2011I will be setting up a computer for people who have very little experience using computers and I want to limit their ability to break things. I'm thinking Linux is the way to go but I don't know what distribution to use. I don't know anything about their hardware other than it is an old laptop. I don't have a lot of experience with Linux, but I would think that without sudo there is not a lot of things you can break.
What would be a good Linux dist that has everything out of the box? (flash, vnc, office, etc) How should I set up the user account to avoid giving them too much power, yet still allowing the computer to be useable for daily tasks? (Will they be able to update software?) I also want to be able to control the machine remotely since I won't have physical access after I set it up, so I am looking into ssh, vnc, (or a better alternative?).

View 3 Replies View RelatedGeneral :: Avoid "privacy Pitfalls" In Windows?
Jun 7, 2010I have a Windows and a Linux machine.In Windows, everytime I visit a site, a lot of cache/history files are created on my machine. I setup my Firefox to don't save anything.but Windows saves a lot of "temp" files, some filenames I opened for example are inserted in registry (like video names). Each video I open in VLC is shown in "Last shown videos". In windows, all files opened can be found at "Recent opened files" as well.
A lot of these privacy configurations can be tweaked (VLC and "Recent opened files" in Windows) - it's a PITA doing it individually, but it's possible - but there isn't a guide to these "internal" privacy traces that are left on Windows installation (inserted in registry for example) In Linux, I just know there are these problems in app level (like VLC), and in "system level "(like bash_history).
is there a complete guide to avoid undesirable traces of what I did/watch/used in my Windows machine? (Delete everytime the PC is restarted, or even avoiding recording these info at all). (I'm mainly interested in config made by Windows itself when installing software and writing to registry. A guide with configuration guides to different types of software is a bonus, I know it's impossible to have a complete guide for it).I'm not interested in a VM machine, since I want to be able do control these issues in my own host and understand the privacy risks involved.
