centos 6 failed to create entries under /dev for newly created loopback devices. Any one know why? and how to fix/workaround it? The steps to duplicate is pretty simple dd if=/dev/zero of=/tmp/deleteme bs=1M count=100 losetup /dev/loop0 /tmp/deleteme fdisk /dev/loop0?? ## created partitions 1, 2, etc. fdisk -l /dev/loop0? ## confirmed that the partitions do exist mkfs.ext3 /dev/loop0p1 ## failed

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 guys, I have Xen 3.0.3 installed with yum on Centos 5.1. I''am facing an issue trying to resize the disk image of a centos 4.5 VM. The VM disk size is 50Go and i need to add 150Go. I tried two methods so far : -------------1st method----------------------- dd if=/dev/zero of=<image file> bs=1M conv=notrunc count=1 seek=2500 * losetup /dev/loop0 <image file> * e2fsck -f

Dear Xen users! In case you were struggling with recent version of th gplpv drivers, I''ve possibly found an LVM related bug in it, and reported to James Harper. Thats''s the point: I''ve tested the mentioned version of your driver on top of 32bit xen-3.2.1 32bit xen-3.3.0 and 64bit xen xen-3.3.0 hypervisors, dom0 was always an appropriate version of a 32bit PAE kernel,

Hi, When I install Oracle RAC on Xen VM, some problem occurred. How can I configure two NICs on a Xen''s DomU. You know, RAC''s installation requires two NICs on a node. I am a newbie about Xen.

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

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, 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

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

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

use /dev/loop0 only when it really contains LiveCD ISO. mount_live should fail silently when LiveCD ISO is not available, which is the case on boot from HostVG/Root.

It looks like you've backuped an entire disk that might contain partitions. So first check if you have partitions inside: sudo fdisk -lu save.dd If you have partitions inside, use the start offset of the partition to create a loopback device (e.g. a partition starts at 56): sudo losetup -o $((56*512)) /dev/loop0 save.dd Now you should be able to use the partition. First check and than
