Ubuntu 10.04, xsane 0.996, Brother MFC 240c scanner.I just finished writing a long dissertation on my problem with this scanning environment (which I will spare you). In a nutshell the resulting image, when printed, is smaller than the original document. In writing my dissertation for this post I determined that the cause of the issue is that xsane believes I am scanning an 8.5 x 14 inch document when I am in fact scanning an 8.5 x 11 letter. So the question is... can I change the size to 8.5 x 11? and if so, how? I have not found anything in the xsane Preferences.

I never been able to use such services on my 2GB KingStone flash drive, because it's sector size is 2048 and the famous linux error: "Not all ... support more than 512B sector size". Although I formatted my flash drive many times and even erased the whole partition table and cleared all flash contents with 0xFF values but it still has sector size of 2048.I want to know where the hell those softwares like "USB Startup Disk Creator" in ubuntu and kubuntu and fdisk in almost all linux distro's get to know that the sector size is 2048?

In the past I have been able to succesfully install ubuntu on several external usb drives with up to 500gb in size.Now I am trying to install a copy of ubuntu 10.10 on an external usb iomega 1tb eGo drive but I am having major issues.The installer reports the total disk size as only 124 gb, instead of the 998gb that gParted reports for the same disk. Proceeding with "use the full disk" installs ok, but it doesn't boot.Grub2 reports that it cannot find the kernel.After some desperate attempts to repartition and after some googling I think that the issue may be with the sector size, which fdisk -l reports as 4096kb (all my other drivers report 512kb) and I have the impression that linux is not ready for it (or I lack the knowledge, which seems more likely).I have also tried to install fedora 14. This distribution reports the correct disk size, installs properly, but again, it cannot boot (Fedora uses grub, not grub2), with a very similar message to the grub2 installer.Because of the way I work, I need my external usb drive to be able to boot linux. And I find it difficult to believe that linux doesn't handle 4096kb sector disks, so here I am asking for help . Please note I am not a linux expert.

So, I thought I would plug the camera in to the laptop with it set to host the card as media when plugged in as USB, in an attempt to fix the formatting issue.
However, when I plug it in to my linux machine, it does not register as a device (e.g., /dev/sda) due to some errors, therefore I cannot reformat it. Essentially, I think I need to fix the partition table but I'm not sure how to when it doesn't register as a device. code...
I'm going to replace damaged HDDs in my server with new drives, which have sector size of 4096 bytes instead of 512. Does CentOS natively support such drives? If yes, since which version? If no, what actions should I take to correctly prepare such a drive to work. How to check that such a drive is correctly recognized by OS?

When I try to do the same thing, however, with a blank disk I get the following message: "mount: you must specify a filesystem type" So I'm assuming I need to prepare the disk somehow.

my question is according to google search I need to umount the filesystem point in order to reduce its size.... so it means I will require that nobody uses the system? since /var logs a lot information?
I also have the option to reduce /root but I think is more complicated.
so what are the precautions in order to reduce /var/?
When I run df it shows the root device is full.

/dev/sda1 9.9G 9.4G 0 100% /
I looked at the inode usage and there is pretty much space available for root device

Question:Several months ago I upgraded my hard drive on a dual boot machine (xp & U9.10 - both 64bit) from approx 80gb to 250gb. I chose to use DriveClone from windows to clone the old drive directly to the new drive. Operational everything works fine. the problem is the Ubuntu HD size went from around 10GB to approx 150Gb, but the filesystem only recognizes approx. 10GB as the total available capacity. I just tried to reinstall Ubuntu without reformatting and only recovered a few GB's. GParted reports the proper partition size. Is there any way I can correct this problem? It's not a big issue...I thought I would check here first before I reformatted the partition. The pre-boot disk check ran and reported no errors but the file system is still not seeing the unused GB's.
View 3 Replies View RelatedWe have 3 RH5u4-64 servers. Server 1 is a standalone server. Servers 2 & 3 are clustered filesystem servers running Veritas CFS 5.0mp3.
Server 1's filesystem is EXT3 and was cloned from a Sun server running Veritas 5.0mp3-VXFS. Filesystem size returned from 'du' 'df' show about 428GB on both the Linux Standalone Server(EXT3) & the Sun Solaris Servers (vxfs).
We then cloned Server 1's filesystem (EXT3) to the 2-node CFS servers. Cloning was successful, but the filesystem sizes returned by 'du' 'df' show 128GB. Block Size for the EXT3 filesystem is 4k while blocksize for the VXFS filesystem is 1k.
Where did that other 300GB go?
I can see VXFS/CFS being slightly more efficient than EXT3 because it's been around much longer, but that can't possibly account for the vast difference.

I am running CentOS 5.5 with a 14T ext4 volume. We are sharing out a few sub-directories via NFS. Our customer was doing some penetration testing with our web app that writes to one of those NFS shares. We are not sure if they did something to cause the metadata to grow so large or if it is corrupt. Here is the listing:drwxrwxr-x 1 owner owner 470M Jun 24 18:15 temp.badI guess the metadata could actually be that large, however we have been unable to perform any operations on that directory to determine if the directory is just loaded with files or corrupted. We have not run an fsck on the volume because we would need to schedule downtime for out customers to do so. Has anyone come across this before
View 2 Replies View RelatedI recently installed Bio-Linux 5.0 as a dual boot system with XP for some bioinformatics applications, but Im having some problems with the amount of disk space which can be allocated specifically for the Ubuntu install.
I partitioned a 250 GB portable hard drive into:
/dev/sdb1: 154.76 GiB (with 30 GiB allocated for Ubuntu)
/dev/sdb2 : 78.13 GiB
Ive been using blastclust to analyse some very large data sets, which keeps on crashing due to filesystem running out of disk space.
When I installed Bio-Linux 5.0 from the live cd, the maximum size I could allocate to the install was 30 GiB, and I havent been able to find a way to change this.
Ive tried using System->Administration->Partition Editor using the live cd, and can view / delete the partitions, but I cant find a way to specifically alter the disk space allocation for Ubuntu.
How do I increase the filesystem size to larger than the current 30 GiB?

View 3 Replies View RelatedI am using Ubuntu live on a i7 x64 with Zotac nvidia. Not sure if Ubuntu started the issue.
When I am using the PC, suddenly the whole display goes blank except for one horizontal line. Even when I restart, the same line will be only visible.
Then I have to wait for sometime with the PC shutdown. After which the whole display will be back. Not sure what is causing the issue.
I suspect its an issue with the graphics card. But just want to know if ubuntu is contributing to the issue in any way.
Over the course of this year, I've been upgrading my system. Started with a mobo/CPU/RAM/video swap, going to a quad core Phenom-II 955 with 4 Gigs of RAM and an Nvidia GT-240 video card. I then dialed up the clock on that CPU, taking it to 3.415 GHz from its nominal 3.2 GHz, and I overclocked the RAM to 1704 MHz from the system default of 1333 MHz. Then I stuffed another hard drive into the box (the sixth HD in the box). Then I shove another 4 Gigs of RAM into the system, for a total of 8 Gigs.
Over this entire exercise, I have not changed the power supply. It was a Coolermaster 500 Watt supply that has served me well and faithfully. I did a careful power budget of this system and concluded that it was sucking somewhere between 420 and 450 watts at full load. Hence, my PS was very marginal. Allowing for derating as the PS aged, I figured I was really close to the edge.
However, I was having no symptoms, so I went with it. My system sits in a room where the temperature is usually around 28 C, and it would idle with a CPU temperature of 40C. Well, I started having some symptoms that were consistent with inadequate power within the last few days. I wasn't terribly surprised at that, so I didn't complain about having to go and buy a new PS. I purchased a Coolermaster GX 750 Watt supply. This is a high efficiency unit.
Since installing it a couple of hours ago, my system is idling with a CPU temperature of 36C. Mobo temp appears unchanged. No changes to BIOS, overclocking is unchanged, and nothing in the system is different except the PS. The case is an Antec P182, which puts the power supply in the bottom of the case inside its own duct. So, the motherboard and CPU don't see any heat from the PS; all of that is exhausted along its own path.
It is too soon yet for me to know if my symptoms that caused me to change the PS are gone, but the temperature change is quite striking. I have no explanation for it. Does anyone else? Temperature is being reported using the sensors command. Mandriva 2010.1 system. Edit: I am also noticing 1 to 3 degree C drops in hard drive temps, while ambient temperature in this room is constant. There are 6 drives in this box, and their temp history has been pretty constant...
