Best way to extend pv partition for LVM
I've replaced disks in a hardware RAID 1 with larger disks and enlarged
the array. Now I have to find a way to tell LVM about the extra space.
It seems there are two ways:
1. delete partition with fdisk and recreate a larger one. This is
obviously a bit tricky if you do not want to lose data, I haven't
investigated further yet.
2. create another partition on the disk, pvcreate another

Safely Remove Disk on LVM
Dear All,
I plan to replace an error disk that is part of an LV. from LVM how-to
it could be done with using pvmove to move all PE from old disk to new
disk.But the howto also said that pvmove is slow. Anyone has
experience using pvmove on 2TB disk?
Is it possible to make all PE on the old disk empty so I don't have to
do pvmove (assuming that I can make a free space >= 2TB). Thank you in

Looking for a life-save LVM Guru
Dear All,
I am in desperate need for LVM data rescue for my server.
I have an VG call vg_hosting consisting of 4 PVs each contained in a
separate hard drive (/dev/sda1, /dev/sdb1, /dev/sdc1, and /dev/sdd1).
And this LV: lv_home was created to use all the space of the 4 PVs.
Right now, the third hard drive is damaged; and therefore the third PV
(/dev/sdc1) cannot be accessed anymore. I would like

Create CentOS 6 system as "clone" of another - with LVM and different disk sizes
Hi,
I just found myself having to set up a new CentOS 6 system with a nearly
identical configuration to an existing host, so I thought I would just
1. Do a minimal install to set up partitions etc. on the new system.
2. Create an image of the existing system using Clonezilla
(http://www.clonezilla.org)
3. Run a Clonezilla restore on the new system.

Upgrade to new drives in raid, larger
Hi all,
As part of my raid experience, I have yet to have to do this, but was
wondering how you guys would attempt it.
I have 3 drives in a raid 1, with one as a hot spare.
They are 250gb with all space used by two raid devices, 1 with boot, the
other with LVMs filling them up.
Now, lets say down the road I want to put in 500gb drives and replace
them....yikes.
I was thinking of taking out the

This is my current config:

Cloning CentOS workstations
I manage a set of CentOS operations workstations which are all clones of each
other (3 "live" and 1 "spare" kept powered down); each has a single drive with
four partitions (/boot, /, /home, swap). I've already set up cron'd rsync jobs
to copy the operations accounts between the workstations on a daily basis,
so that when one fails, it is a simple, quick process to swap

automated remote cloning
Good morning/day and Happy New Year.
We have a geographically distributed environment (marketing speak: cloud) where we regularly need to migrate individual systems to new hardware (for bigger disks or for better geographical placement, for example). We currently use Cobbler to do our base installs automatically and I am now looking at integrating Clonezilla with Cobbler. The goal is take an

Changing disk UUID after cloning
So, I have a CentOS 6 system, and I want to make several clones of it. I'm using Clonezilla to clone the drives; that's no problem. But the drive UUIDs are driving me up the wall. After cloning, the two drives have the same UUID, but I'd like each clone to have different UUIDs so there's no possibility of a conflict when I am running diagnostics with two drives installed, etc.

LVM - pvmove and multiple servers
Hi All.
Looking for some guidance/experience with LVM and pvmove.
I have a LUN/PV being presented from a iscsi SAN. The LUN/PV is presented
to 5 servers as a shared VG they all have LV's they use for data, they are
all connected via iSCSI.
As the SAN I am using is being replaced I need to move onto a new unit.
My migration strategy at this time is to

I have a 4,1TB Logical volume consist of four disks with size of 2TB,

that I can replace it with 2TB disk. most LVM tutorial ask to use

Hardisk cloning for centos-5.3

I want to clone my hardisk containing the centos-5.3 OS and its swap
region on to new raw hardisk via network

Is there any Tool for that or will DD command be sufficient.I know that dd

Clonezilla SE with CentOS5
Hi all,
I'm looking for a cloning solution for our Windows/Linux/*nix computer park
and ran into Clonezilla. Apparantely the DRBL and other documentation
mentions CentOS as a suitable base for it.
Does anybody on this list use this solution and can say something about it
in the running-Clonezilla-with-CentOS-context, be it recommendations,
gotchas', warnings or whatever?
Thanks.

MAC address changes after cloning
Hi,
I have x86 system and have used clonezilla to clone the entire hardisk of
system A and restored it on another x86 system, system B.
After the cloning process, i notice that the MAC address of the system B
in the /etc/sysconfig/network-scripts/ifcfg-eth0 is changed and
is having the MAC address of system A.
The interesting part is that if i do an ifconfig from the bash prompt, the

[Marketing Mail] Create CentOS 6 system as "clone" of another - with LVM and different disk sizes
Hi,
You can simply boot a live system to create your partition layout and copy it
over the existing system with rsync. Once your system is copied, you will need
to customize all hardware-dependent configuration files such as {crypt,fs}tab,
network configurations, bootloader and so on depending on your setup.
Don't forget to install the bootloader afterwards!
You can also install a minimal

upgrading storage on hardware RAID 10 possible?
Hi all,
Can anyone please tell me, from experience, if it's possible to
upgrade the hard drives in a RAID 10 system from 250GB HDD's to 500GB
/ 750GB HDD's, while the server is running? The server runs CentOS 5.5
x64.
Our hardware vendors simply always say no, so we never actually tried
doing this, and when a client needed an upgrade like this we had to
build a new server with the
