I tried it on loop. 1. mount /dev/loop0 /mnt/test -t ext3 2. cp files to 100% full 3. umount /mnt/test 4. fsck.ext3 -f /dev/loop0 Inode xxxxx, i_blocks is xxx, should be yyy. Fix?

Hello Mailing List! A quick question. Has anyone gotten a resize (in my case grown) a Xen DomU disk image? Here is the procedure I have followed: 1. Install a DomU using virt-install Customize xvda to be all one partition ext3 2. On Dom0: dd if=/dev/zero bs=1G count=1 >> <my_disk_image> ll -h (Image is now 1GB larger) xm create <DomU> On DomU: df -h (Size has not

I've been trying to figure this one out for some time now without success and can't find anyone else with this exact problem, so hopefully there's a guru around here that might be able to point me in the right direction. I've got a copy of Dark Reign I want to play on my netbook. The problem is that I only have a USB CD drive which I don't normally connect, but can for a

Hey, guys. I have a problem when installing syslinux 4.06, and I'd be grateful if someone could tell me how to solve the problem. My task - to install the bootloader on the virtual machine image. The image contains the MBR and the only partition with the file system ext4. The file system contains all the files for the guest OS. To install bootloader into the image of the guest OS, I use the

hi all, i have SCEVAddRec {{(32 + @edge.8265),+,32}<Loop0>,+,4}<Loop1> where Loop0 and Loop1 are brothers (loops at the same level of the loopnest), and Loop0 have a computable backedge taken count. when i call getSCEVAtScope({{(32 + @edge.8265),+,32}<Loop0>,+,4}<Loop1> , Loop1), it just give me a {{(32 + @edge.8265),+,32}<Loop0>,+,4}<Loop1>, instead of

Hello, here is the second release of kpartx : the shameless perversion of util-linux's partx. As before it : 1) compiles against klibc 2) read partitions table like partx 3) drives the device mapper to present the partitions bdevs Find it at http://dsit.free.fr/kpartx-0.0.2.tar.bz2 This release adds a interesting functionality : it can now read partitions tables from regular files,

Hi, just out of curiosity: Within a kickstart postinstall script, I tried to do a loop mount, which failed. It turns out that there is no /dev/loop0 (no /dev/loop<x>). After creating it with mknod /dev/loop0 b 7 0 everything works fine. Now this script executes in the chroot system. This is the system on the hd. A plain chroot system should not have any /dev or /proc mounted. But

Hi, I'm trying to build a bootable MSDOS disk and put it on a ISO with floppy and hard disk emulation. I want to use commonly available Linux tools like dd, losetup, mkdosfs, memdisk etc. I have done the following: 1. dd if=/dev/zero of=myImage bs=1M count=50 [ Builds a 52MB image ] 2. losetup /dev/loop0 myImage [Links /dev/loop0 to myImage file ] 3. vi /grub/stage1; %!xxd; [ NULL the partion

Here's the problem. We perform full tar backups of our CentOS 4/5 machines in real-time at regular intervals. And when a disaster happens, we are able to restore those backups onto virgin filesystems, make the /dev/null, /dev/zero and /dev/console devices .. and boot the machine. This has worked well on standalone systems, and also on Xen 3.0.3 guests on CentOS 4.4 machines, where each guest

Hi, I have potentially found a (minor) bug (or missing feature) in btrfs, but it might be a misunderstanding, so I like to ask here first before reporting in Bugzilla. I have a btrfs file system in RAID1 mode with two missing devices, but I know that all data is still present on the remaining device. btrfs refuses mounting this fs in rw mode (too many missing devices), as it probably just counts

hi ya syslinuxerz - i've been slowly working on a making a custom bootable standalone usb-stick with X11 and kde - it's basically builds itself off of a slackware-10.1 server - create a custom initrd.gz ( /dev/ram0 ) http://linux-boot.net/Bootable/InitRD/ - create a custom rootfs.gz ( /dev/loop0 ) http://linux-boot.net/Bootable/RootFS/ - create X11 and kde loopfiles

I'm trying to use a shareware program called PowerISO to extract a .daa cd image to a raw iso9660 format so that I can view the contents.

I had to create a single floppy image holding the kernel and initrd of SuSe8.0 distibution. When I boot the computer, it first loads the kernel, and starts loading the initrd. After a short while it halts saying ?Boot Failed: please change disks and press a key to continue.? The floppy image is served by a PXE server, so I am not sure if the problem I am facing has anything to do with ?bad

Have been trying some things, but something isn't working at least with using Virtual Box with EFI option. With it off, the cd boots as normal, and works, but with EFI on, it has an error that flashes on screen, and then it drops to a shell prompt. I'm hoping it is just a dumb mistake I am making, and can be resolved. Perhaps I've named the directories incorrectly, or there is a
