How to manipulate xen image size
Hello All,
We would appreciate your advice on the following issue.
We have created a full virtualized Xen guest that its disk is an image file
of 4GB.
We want to use this image file as a template for creating Xen guests which
their disk will be an LVM device.
The disk image file is of type:
file /var/lib/xen/images/rhel52.img
/var/lib/xen/images/rhel52.img: x86 boot sector;

OT: piped greps with regex
List,
Happy NY.
>From the bash command below, I'm trying to parse out the startsector value:
$ sudo file mini_vusb.img
mini_vusb.img: x86 boot sector, Microsoft Windows XP MBR, Serial 0x25d84; partition 1: ID=0xe, active, starthead 1, startsector 32, 390496 sectors
First try was with grep/egrep but I wanted to capture 'startsector 32' as a group (). Nothing came close to working.

Full Virtualized DomU won't boot
Hi, I use Centos 5.4 x86_64

syslinux installation problem
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

Merging os and updates
I've been able to successfully kickstart CentOS 3.9 from the base
repo, but no such luck after merging os and updates. I think I did
everything right - updated base/comps.xml and regenerated
hdlist/hdlist2. Updated the yum repo as well although I'm pretty sure
it's not used by anaconda.
This is difficult to debug. The setup is running under kvm on a CentOS
6.4 host, and for some

Re: Bug#637234: linux-image-3.0.0-1-686-pae: I/O errors using ext4 under xen
Hi Konrad,
Does this look at all familiar? There is some more info in the full bug
log at http://bugs.debian.org/637234 . In particular, contrary to the
message below, the user subsequently confirmed that the issue appears to
be Xen specific (doesn''t happen on native or vmware) and that it arose
between 2.6.39-2-686-pae and 3.0.0-1-686-pae.
Could it be related to edf6ef59ec7e

mdadm --create on Centos5?
Is there some new trick to making raid devices on Centos5?
# mdadm --create /dev/md3 --level=1 --raid-devices=2 /dev/sdc1 /dev/sdc1
mdadm: error opening /dev/md3: No such file or directory
I thought that worked on earlier versions. Do I have to do something
udev related first?

Looking for Insights
Hi Guys,
I had a strange problem yesterday and I'm curious as to what everyone
thinks.
I have a client with a Red Hat Enterprise 2.1 cluster. All quality HP
equipment with an MSA 500 storage array acting as the shared storage
between the two nodes in the cluster.
This cluster is configured for reliability and not load balancing. All
work is handled by one node or the other not both.

CentOS 7: software RAID 5 array with 4 disks and no spares?
Hi,
I just replaced Slackware64 14.1 running on my office's HP Proliant
Microserver with a fresh installation of CentOS 7.
The server has 4 x 250 GB disks.
Every disk is configured like this :
* 200 MB /dev/sdX1 for /boot
* 4 GB /dev/sdX2 for swap
* 248 GB /dev/sdX3 for /
There are supposed to be no spare devices.
/boot and swap are all supposed to be assembled in RAID level 1 across

How does LVM decide which Physical Volume to write to?
Hi everyone.
This isn't specifically a CentOS question, since it could apply for
any distro but I hope someone can answer it anyway.
I took the following steps but was puzzled by the outcome of the test
at the end:
1. Create a RAID1 array called md3 with two 750GB drives
2. Create a RAID1 array called md9 with two 500GB drives
3. Initialise md3 then md9 as physical volumes (pvcreate)
4.

btrfs-convert complains that fs is mounted even if it isn't
Hi,
I''m trying to run btrfs-convert on a system that has three raid
partitions (boot/md1, swap/md2 and root/md3). When I boot a rescue
system from md1, and try to run "btrfs-convert /dev/md3", it complains
that /dev/md3 is already mounted, although it definitely is not. The
only partition mounted is /dev/md1 because of the rescue system. When I

ext3 errors
I recently set up a new system to run backuppc on centOS 5 with the
archive stored on a raid1 of 750 gig SATA drives created with 3 members
with one specified as "missing". Once a week I add the 3rd partition,
let it sync, then remove it. I've had a similar system working for a
long time using a firewire drive as the 3rd member, so I don't think the

Hosed my software RAID/LVM setup somehow
CentOS 5, original kernel (xen and normal) and everything, Linux RAID 1.
I rebooted one of my machines after doing some changes to RAID/LVM and now
the two RAID partitions that I made changes to are "gone". I cannot boot
into the system.
On bootup it tells me that the devices md2 and md3 are busy or mounted and
drops me to the repair shell. When I run fs check manually it just tells
