An LVM snapshot is an exact copy of an LVM partition that has all the data from the LVM volume from the time the snapshot was created. The big advantage of LVM snapshots is that you don't have to worry about open files and database connections, and you don't have to interrupt/halt services on the live partition because a snapshot is usually created in fractions of a second, so your users won't notice any disruption, and your snapshot holds consistent data. falko Sun, 15 Apr 2007 21:11:26 GMT http://www.howtoforge.com/how-to-back-up-mysql-databases-with-mylvmbackup-on-ubuntu-12.10 mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on an Ubuntu 12.10 server. falko Tue, 15 Jan 2013 11:19:30 GMT http://www.howtoforge.com/set-up-raid1-on-a-running-lvm-system-debian-etch This guide explains how to set up software RAID1 on an already running LVM system (Debian Etch). The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one). falko Tue, 25 Mar 2008 10:34:08 GMT http://www.howtoforge.com/how-to-set-up-software-raid1-on-a-running-lvm-system-incl-grub2-configuration-debian-squeeze This guide explains how to set up software RAID1 on an already running LVM system (Debian Squeeze). The GRUB2 bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one). falko Wed, 15 Jun 2011 09:34:03 GMT http://www.howtoforge.com/how-to-set-up-software-raid1-on-a-running-lvm-system-incl-grub2-configuration-ubuntu-10.04 This guide explains how to set up software RAID1 on an already running LVM system (Ubuntu 10.04).

This should work - with minor changes - for other Debian and Ubuntu versions as well. By following this guide, it is possible to configure the system to your needs (OS version, partitioning, RAID, LVM, etc.) instead of depending on the few pre-configured images that your server provider offers. falko Thu, 17 Jan 2013 13:43:01 GMT http://www.howtoforge.com/recover_data_from_raid_lvm_partitions This tutorial describes how to rescue data from a single hard disk that was part of a LVM2 RAID1 setup. Why is it so problematic to recover the data? Every single hard disk that formerly was a part of a LVM RAID1 setup contains all data that was stored in the RAID, but the hard disk cannot simply be mounted. First, a RAID setup must be configured for the partition(s) and then LVM must be set up to use this (these) RAID partition(s) before you will be able to mount it. I will use the Knoppix Linux LiveCD to do the data recovery. falko Mon, 23 Apr 2007 07:55:20 GMT http://www.howtoforge.com/using-raw-devices-in-virtualbox-vms Usually, VirtualBox creates its virtual machines in disk images (.vdi, .vmdk, etc.). This tutorial explains how you can use RAW devices from the host (partitions, LVM volumes, etc.) and create a VirtualBox VM in it. I will also explain how to mount a RAW device in an existing VM. falko Tue, 24 Jul 2012 09:43:51 GMT http://www.howtoforge.com/virtualbox-creating-backups-and-clones-of-running-virtual-machines-no-downtime-with-lvm-snapshots If you use LVM volumes for your VirtualBox VMs, you can create backups and clones of a running VM without shutting it down. This tutorial shows just that: using LVM snapshots to create backups and clones of running VirtualBox VMs without downtime. falko Thu, 26 Jul 2012 09:01:03 GMT
