similar to: mount xen partitions inside logical volume from dom0?

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'm new to lvm. I decided to decrease the space of a logical volume. So I did a: $ df -m Filesystem 1M-blocks Used Available Use% Mounted on /dev/mapper/VolGroup00-LogVol00 1953 251 1602 14% / /dev/sda2 494 21 448 5% /boot tmpfs 1014 0 1014 0% /dev/shm

I''ve succesfully installed FC6 domU under RHEL5-beta2 dom0 with virt-manager. I could open a graphical vnc console from virt-manager with no probs and use domU''s gnome desktop. After few days of running the guest I''ve updated it with yum and been using it mostly via xm console. Now I tried to use the graphical console, but all virt-manager was telling me was: "The

Hi all, I am trying to mount images that I previously created with dd and the images have two partitions (swap and LVM). I use these images to house data for my Xen Guests. For some reason (possibly Kernel conflicts for paravirtualized domains) I am unable to boot my Guest images. Failing which I would like to mount the disk images and atleast get my data out of them. dd -o loop server.img

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

I'm playing with software RAID and LVM in some virtual machines and I've run into an issue that I can't find a good answer to in the docs. I have the following RAID setup: md0: sda1 and sdb1, RAID 1. This is /boot md1: sda2 and sdb2, RAID 1. This is a PV for LVM. VolGroup00, this is the volume group and md1 is the only PV in it. LogVol00 is swap LogVol01 is / LogVol02 is /home

Run: # top # vmstat 1 # iostat -x /dev/emcpowerb 1 The latter two you can save to a file. For top, just monitor cpu usage and see if any process is hogging all of it.

I am trying to install CentOS 4.6 to a pair of 750GB hard drives. I can successfully install to either of the drives as a single drive, but when I try to use both drives and mirror the partitions, I start having problems. Anaconda crashes as it is trying to format the drives. This is what I'm trying to create: /dev/md0: 200MB, /boot /dev/md1: 2GB, swap /dev/md2: rest of the

Hi all I want to shrink one of my LVM based domU''s, but don''t quite know how to do it. I have searched the Wiki & HOWTO''s, and they all show you how expand / enlarge a LVM based domU, but not shrinking it. So, I stopped (destroyed) the domU, and then resized it as follows: lvresize /dev/data/cpanel1 -L10GB (It was 100GB), but when I a started it up again, I

Hi. I am new to CentOS (Debian user) and I am looking for way how to install CentOS 5 on domU in the way that I have it directly on dom0 LVM partition. If I install it with virtual-manager then the installation program takes that partition as a disk and then creates new partitions on it. I don''t want it that way because I cannot then mount it from dom0. Is there some way how to

domUloader potentially makes my life a lot easier, but from experiments and looking at the code, it doesn''t seem like there is any way to pass kernel command line arguments with it. Am I just missing something? Thanks, John Byrne _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello, I'm in a slightly unusual situation and I'd really appreciate some advice. I installed CentOS 5.2 on a server about a month ago. Today I happened to check the 'free' command and noticed that the Swap line reads as follows: Swap: 0 0 0 I'm pretty certain that when I installed the OS and created a custom partition table, that I defined a

Hey all, This utility (from Qemu) might be useful to anyone who has multiple partitions on a file-backed VBD and wants occasionally to mount them in dom0. http://www.dad-answers.com/qemu/utilities/QEMU-HD-Mounter/lomount/ You can tell it what partition to mount out of the file and it sorts out the offsets, etc. by parsing the partition table. This allows you to get around the loop

I began an update of one of our servers via yum and, coincidentally or not, I have been getting the following logged into the message file since: messages:Jan 7 15:55:51 inet07 kernel: post_create: setxattr failed, rc=28 (dev=dm-0 ino=280175) Now, this tells me that dev dm-0 is out of space but, what is dm-0? So, can anyone tell me what is happening and why? -- *** E-Mail is

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

Hi, I have a C5.8 machine with several DomU's. I fubared the fstab on one of them and I need to get it into single user mode. Does anyone know how to do that? I tried adding single to the extras line in /etc/xen/machine_name but it still tries to start in level 3. To make things worse, the root partition is on LVM. Alternatively, does anyone know how to access the image from DomU? I tried
