Hi, I am trying to recover data from my old system which had LVM. The disk had two partitions - /dev/sda1 (boot, Linux) and /dev/sda2 (Linux LVM). I had taken a backup of both partitions using dd. Now I am booting of CentOS live cd for system restore. I recreated partitions like previous system using fdisk and then used dd to dump all the data onto it. I would like to mount sda2 as LVM, but I

Hello everyone, I am trying to install windows xp as a guest OS. It runs through the installer just fine, but every time I reboot, it keeps booting back to the installer. Here is my config: ------------<code>--------------------------------------- kernel="/usr/lib/xen/boot/hvmloader" builder="hvm" memory=512 device_model=''/usr/lib/xen/bin/qemu-dm''

Hello everybody, I am in the process of setting up a really cool xen serverfarm. Backend storage will be an LVMed AoE-device on top of DRBD. The goal is to have the backend storage completely redundant. Picture: |RAID| |RAID| |DRBD1| <----> |DRBD2| \ / |VMAC| | AoE | |global LVM VG| / | \ |Dom0a| |Dom0b| |Dom0c| | |

I have a centos 5.6 server that has xen domUs installed on their on logical volumes. These logical volumes contain their own volume groups and again their own logical volumes. I want to access the domU logical volumes and tried this: [root at kr ~]# fdisk -l /dev/VolGroup00/LogVol02 Disk /dev/VolGroup00/LogVol02: 274.8 GB, 274877906944 bytes 255 heads, 63 sectors/track, 33418 cylinders Units =

I am trying to mount this (my old hard drive) from my Centos 5 install as a USB drive so I can copy files over. I have made the change to max_luns so that I can have more than one drive on a USB drive. The first partition, /dev/sda1 mounts automatically as /boot_ The second partition, /dev/sda2 is the one I really want and it is an lvm partition. When I am booted from this drive (as the

CentOS 7 for everything I am probably never using lvm again. I have never not once actually benefited from its capabilities but this is probably the third or fourth time it has gotten in my way. Issue is that I use the tools so rarely that I can't recall what needs to be done to properly mount the drives on another system and finding that info on the web is becoming more difficult as the

Hi, We just migrated xen on gentoo on amd64 from 4.0 to 4.1 and encountered a few issues that were not documented. Here is how we solved them and what issues are remaining: 1. Our config files were referring to the LVM devices like /dev/vg/domU-root with disk = [ ''phy:vg/domU-root,sda1,w'' ]. This does not work anymore, we have to include ''/dev/'': disk = [

Hi guys, sorry if this is trivial, but I have been googling a couple days and already compromised a test disk trying to figure this out, so I thought it is time to ask for some advice. I have a disk that comes from a clean and working CentOS4.2 install, and I am trying to use an external usb to ide converter to mount it on another workstation with CentOS4.2. I am trying this to better

Suse 10.1 AMD64 Xen3 New to Xen. The dom0 is up and running. I am trying to get my first domU working. My approach is to use precompiled images from jailtime.org. After some manual tinkering with the .cfg file the domU proceeds to boot but stalls with the following error. I cannot get past this - any ideas ? Brian Using config file "/etc/xen/vm/vm1".

Hi all, One of our Dell servers has failed badly, and one of the domU's has been corrupted in the process. It boots up to a point and then gives me a kernel panic: Loading dm-zero.ko module Loading dm-snapshot.ko module Scanning and configuring dmraid supported devices Scanning logical volumes Reading all physical volumes. This may take a while... No volume groups found Activating

I have a CentOS-6.8 system which has a suspected HHD failure. I have booted it into rescue mode from a CentOS-6.5 minimal install CD in order to run fsck -c on it. The system hosts several vms. I have activated the lvs associated with these vm using pvscan -s ; vgscan ; vgchange -ay. An lvscan shows the lvs as ACTIVE. None are mounted. When I try to run fsck on any of them I see the
