Ubuntu Servers :: Strange File Names - Getting Larger And Larger All The Time

May 3, 2011

Using Samba I have looked into the file that stores all my web sites, there were a few strange files that get larger and larger all the time. File names are _Za01716 and _Za01820, they are nearly 50mb in size now. I know these are not Log files so what are they and can I delete them?

Ubuntu :: Opening Files Larger Than 2GB?

Feb 28, 2010

I have this file that is about 3.6GB, I'm trying to open it through wine. But it gives me an error saying I can't open it. I'm not sure if this is a problem with wine, or do I need some special code to put in the terminal?

Ubuntu :: Type Ext4 Partition Won't Let Copy Files Larger Than 4.1 Gb

Jun 30, 2010

I erase XP and do a clean install of 10.04 netbook remix on my Acer AspireOne. Almost everything seems to be working ok (so far.....3hrs after installation and still testing!) except for:

1: My main partition is formatted as ext4, and when I try copy back any (video .iso !) file that is larger than 4.1 gb I get a memory error and so only copies the file incomplete up to 4.1 gb. I know this problem under windows FAT vs NTSF but I have read that ext4 was beyond this... So what did I do wrong? Is the solution to switch the ext4 to ext3 and can this be done without loss of installed programs or files.

2: Video and Sound with video is not good. Lots of disturbance/turbulence and for sure not optimal for both video and sound.

3: my internal micophone is not working in Skype but it does with Sound-Recorder...I connected external mic and this works, but with lots of disturbance. Also the voice sound from telephone calls sound is not as should be.

The "hardware drivers" utility tells me that all is good and no proprietary drivers are in use on the system.

Ubuntu Security :: Secure-delete Won't Work On Larger Files / Sort It?

Sep 16, 2010

I'm trying to clean a hard drive and I'm using secure-delete but it just stands there and takes cpu power but nothing happens, I used -r switch first and nothing, so I tried it on single files, small pictures worked as intended but a simple 50MB MPG file just stands there as well and nothing happens.

I left it running for 24 hours and nothing happened but the cpu was working at 90-100% all the time :/

Any one know what's wrong? I'm using 10.04 UNR

Ubuntu Installation :: Create Larger Then 4GB Casper File?

Nov 23, 2010

I have recently been experimenting with installing Ubuntu 10.10 on a USB/Flash drive, and have finally stumbled on the "Universal USB Installer", using a so-called "Casper" file for persistence.Now I wanted to make the Casper file bigger, and found this article:I was reading it, and got confused at this part:"This tutorial assumes that you have already created a bootable USB Flash Drive that contains Ubuntu or an Ubuntu based Live Distro like Xubuntu, Kubuntu, Linux Mint, Crunchbang, etc. You should delete any existing casper-rw file from the drive to free up all available space before proceeding.

1. Restart your Computer, booting from an Ubuntu Live CD"Do they mean that you have to make 1 flash drive that was created with the Universal USB Installer, and has a Casper file on it, AND you have a Live CD from which you operate?If so, could I use one flash drive that acts like a Live CD (without the Casper file), and create another flash drive that DOES have the Casper file, and then boot from the one without, and follow the instructions? (Sorry for the complex sentence, didn't know how other to put it...)

Ubuntu Servers :: Options For A Larger File System?

Apr 27, 2011

I have considered a range of choices, but at the end of the day the choice I make can quite easily put into a situation that requires even more thinking.

The idea is to have an enormous file system for SAMBA that can scale from terabytes to petabytes. Such as a single directory with say 4 million MP3s in my iTunes collection. iTunes cannot use multiple drives easily.

There are lots of vendors that have offerings galore, I wanted to see what can be done with a roll your own approach.

Ubuntu Installation :: How Makes Larger 'file Systems' Using /etc/fstab

Mar 12, 2011

I have noticed the (understandable) tendency of new Linux users to think about disk drives in the 'Windows way'; their first thought is to exchange a new drive for an existing one, rather than combine both drives for a larger 'file system'.

There are times when replacing one drive with another is indeed the correct action (aging drive, failing drive, slow drive, etc). But in other cases it may be preferable to use the inherent strength of the fstab (file system table) file to combine physical drives to become a larger 'file system'.

Lets first look at a user with an 8 gig netbook who is running out of space. Rather than replace the 8 gig flash drive with a 32 gig device, the old and new devices can be combined to yield a 40 gig 'file system':

This same principle can be applied to a user with a computer using an 80 gig hard drive, and who 'adds' a new 320 gig drive instead of replacing the 80 gig drive with the 320 gig drive:

This same principle can also be applied to building a massive 'file system' without the requirement of using RAID:

The above 12 terabyte system can be built using a basic motherboard with four open SATA ports and four 3tb hard drives. No server based equipment is needed; no raid hardware or software is required. This is just something that Linux does (and does very well).

General :: Disk Based Text Editor To Edit File Larger Than Memory?

Aug 2, 2010

I am using Ubuntu and looking for a good editor to edit a file that is > 4GB. I just need to put content at the end and beginning of the file. I suppose I could use something like

cat "text to add" >> huge_file

To append to the file. Is that the route to go? What about prepending? In general, what is the best route if I wanted to edit somewhere in the middle?

I've tried VIM and it fails miserably. I assume emacs and nano would be even worse. What else is there? I assume to accomplish what I am looking for, the editor would have to be specifically designed for this by not keeping the entirety of the file's contents in memory.

Ubuntu :: Larger Resolutions In KDE?

Ubuntu Installation :: Make /tmp Buffer Larger?

Mar 16, 2010

I have read that if /tmp is too small, videos choke, and other problems occur.

On my machine, one of the problems was that I couldn't download things because /tmp got full and when I went in to delete some tmp files, I wrecked the system...(not too intuitive I guess).

So this time around, how can I increase the size of /tmp, as well as have it emptied on startup?

I don't want to have it emptied on shutdown, because if I get a crash, the /tmp will still be full...shutdown just doesn't seem to be a reliable place to put essential housekeeping tasks.

Ubuntu :: Any Way To Make Power Icon Larger In 10.04?

Sep 8, 2010

Is there any way to make the power Icon at the top right of gnome panel larger in 10.04? This has been a problem for a while now. For people with less than perfect eyesight (my mother) it is far too small to be functional. Increasing the size of the panel to something useful on a large screen increases the size of most icons also, but the power button remains resolutely tiny. Another problem for her is the selection of window edges (too be honest, I find this frustrating myself) The selection area is incredibly small on a 22" screen and impossible for her to select.

Ubuntu :: Replacing With Larger Drives In RAID 6?

Jun 14, 2011

I have a RAID 6 built on 6x 250GB HDDs w/EXT4. I will be upgrading the RAID to 4 2TB HDDs.

How would one go about this? What commands would need to be ran? I'm thinking about replacing the drives 1 at a time and letting it do the rebuild, but I know that would take a lot of time (which is fine). I don't have enough SATA ports to setup the new RAID and copy things over.

Ubuntu :: Migrate To A Larger HD, Dumping Windows?

Aug 13, 2011

I currently use Xubuntu on a dual boot system, a laptop. The hard drive is to small (30 GB shared between Xubuntu and windows), so I want to clone the existing drive, but I do not want to clone windows.

I bought a 120 GB hard drive, and want to dump windows totally. If I download clonezilla and burn it to a cd, can I instruct it to only clone the Xubuntu system? I think I would run clonezilla from a cd, download everything to my USB drive, then remove the small hard drive. Then, install the bigger drive and restore everything to the newer and larger drive. Will this work??

General :: Clone A Larger Disk To Smaller With Cp?

Jul 10, 2010

I need to clone a 160GB hard drive with Linux Mint 9 (not more than 10GB used) to a 30GB SSD that is partitioned carefully (aligned to cylinder boundaries) and is currently running Ubuntu (which I wish to overwrite with Linux Mint 9). The SSD has a /boot partition, / and swap. The source (160 GB) does not have a separate boot partition. Can anyone help me fill in the steps below? /dev/sdc will be the source (160GB) and /dev/sda is the target (with partitions 1,2 and swap on 5).

make a copy of /etc/fstab from the target drive before proceeding. Ready the target partitions. Can I reuse the existing destination partitions on the SSD? Ready the filesystems on each of the target partitions. /boot is ext2, / is ext4 and swap is already set up too. As I said, all contain data (Ubuntu) that I wish to overwrite. So what steps are needed here? Do I need to erase anything (files, etc.) before the copy/clone? next, use dd to copy MBR (right?) And exclude partition table:


dd if=/dev/sdc1 of=/dev/sda1 count=1 bs=446

Mount the source and destination drives:


mount -t ext4 /dev/sdc1 /mnt/source
mount -t ext2 /dev/sda1 /mnt/boot_target
mount -t ext4 /dev/sda2 /mnt/root_target

I suppose I can leave the swap partition on the target untouched. Copy the files from the source partition to the destination


cp -a /mnt/source/boot /mnt/boot_target
cp -a /mnt/source/ /mnt/root_target

then I assume I go to /mnt/root_target and delete the /boot directory, right? Change /etc/fstab to reflect the new partitions. I mount by label. Will my partition labels be intact after this? Do I have to make any changes to GRUB? Anything else?

Ubuntu :: DD Image Restores Larger Than Actual Size

Feb 13, 2011

I've been working on getting another OS installed on my computer for one of my classes (OS specific assembly instructions). To get this OS running, I had to start using a GPT rather than a MBR table. I backed up my Ubuntu partition (ext4) using the old-fashioned dd command. I've since been able to get everything working again after a dd restore.

The problem is that my original Ubuntu partition was only about 50GB and the dd image only takes up 40 GB. After I restored the image to the new drive (146BG), gparted is reporting 119GB used and only 26GB free. What can I do to reduce the size of my install to 40GB again?

When looking at the disk in baobab, it says the the filesystem is only 47.2 GB and that only 20.9 GB has been used. This is likely what the old partition's breakdown was. So my new question is: How can I make the filesystem capacity (47.2 GB) equal that of the partition that it is on (146 GB)?

Ubuntu :: Move /home To Larger Hard Drive?

Jun 19, 2011

I'm sure that this is posted somewhere but I have not been able to find the right search terms. I have a Dell Vostro 1700 which has 2 physical hard drives. I installed Natty to the 1st drive and during the install I used the entire 2nd drive as /home. I would like to upgrade the 2nd drive to a larger faster drive. I have the new drive in a USB enclosure so that I can access both drives. I'm pretty sure I need to boot from the CD to do this. Then I need to copy all files unmount the small drive then shut down, install the larger drive and have the system recognize it as /home. I am just starting to creep out of N00B stage and don't want to screw this up.
