Setting up an LVM filesystem is quite easy assuming you have the right tools installed and a recent kernel. LVM has a lot of advantages, most notably the ability to take snapshots of the current filesystem – this is why LVM is often used in live database environments. Assuming a Debian Lenny machine, get the relevant packages. Some may already be installed: apt-get install lvm2 dmsetup mdadm In this example, we will assuming that /dev/sda is your boot drive, and that you want to leave it out of your LVM array, but include /dev/sdb and /dev/sdc. Both /dev/sdb and /dev/sdc should be of equal ... Read Full Story

Moving a Xen Guest into an LVM container from a loopback sparse image is easy enough. You’ll need to power down the VM using xm shutdown mymachine Once done, create the logical volume with: lvcreate –name mymachine-disk –size 10G myvg 10G should match the exact size (if not more) of your current VM. Now create the same for the swap file: lvcreate -name mymachine-swap -size 128M myvg . Now edit your machine’s config (/etc/xen/mymachine.cfg), replacing the disk part from: disk = [ 'file:/xen/mymachine/mymachine-swap,sda1,w', 'file:/xen/mymachine/mymachine-disk,sda2,w', ] to disk = [ 'phy:/dev/myvg/mymachine-swap,sda1,w', 'phy:/dev/myvg/mymachine-disk,sda2,w', ] And use dd to write the disk to your new LVM filesystem: ...

(This blog entry is my German translation of my original blog entry on Sun Ray and ZFS at JavaOne 2009) Was passieren kann, wenn man zwei beeindruckende Technologien auf intelligente Weise kombiniert, konnte man in diesem Jahr auf der JavaOne-Konferenz beobachten: Mehrere Tausend Desktop-Umgebungen wurden mit einer Kombination aus Sun VDI Software 3, ZFS, Sun-Servern and Sun-Speichersystemen dargestellt. Hier einige bemerkenswerte Fakten...
