	The Logical Volume Manager (LVM) - Part 2
		The difference to a setup where the root-system is stored on a physical partition and LVM only manages extra space is that LVM is usually activated during boot time, but for this setup it already has to be active before the just-started kernel can even mount the root filesystem to start the init process.
		Do not immediately go into LVM setup, although it is presented to you right at the beginning next to the partitioning option and there is a partitioning option in the LVM setup dialog which could be used.
		The problem is that at installation time the LVM setup including the device files for the logical volumes exists in the installation system only, but LILO runs chroot in the installed system, which does not have those device files yet since they are created automatically as soon as that system boots up.

	Notes on using logical volumes and the Logical Volume Manager (LVM)
		The term LVM strictly applies to the Logical Volume Manager (the replacement for FDISK) but it is commonly used as a name for the whole 'system' that implements logical volumes.
		That is, use LVM to delete any existing Boot Manager, then install it again (thus updating the copy on your hard disk to the version embedded in LVM).
		Ask LVM to create a new volume, and when it asks if it's to use an existing partition, say yes and then tell it the partition that used to be drive F:.

	The Logical Volume Manager (LVM) - Part 1
		This LVM hides the details about where data is stored, on which actual hardware and where on that hardware, from the entire system.
		This means LVM on a shared storage cluster has to be setup only once on one node, and all other nodes that can "see" the storage at all automatically set themselves up when they are booted.
		LVM is one more tool to achieve high availability, and you have to use many of them together like RAID on the disk level, LVM for all storage management, HA software (heartbeat and application monitoring), and a backup strategy.

	lvm
		If lvm is invoked with no arguments it presents a readline prompt (assuming it was compiled with readline support).
		LVM commands may be entered interactively at this prompt with readline facilities including history and command name and option completion.
		If lvm is invoked with argv[0] set to the name of a specific LVM com- mand (for example by using a hard or soft link) it acts as that com- mand.

	About Us - LVM - LVM - Latvijas Valsts Mezi (Site not responding. Last check: 2007-10-20)
		The LVM represents interests of the state in forest management ensuring the preservation and increase of forest values as well as the highest possible income.
		Uģis Rotbergs, WWF Latvia manager: “Foundation of the LVM has created preconditions for forestry in the state-owned forests of Latvia to base its activities on the principles of entrepreneurship, that is, to invest resources in the company and gain economic benefit in the future.
		It can be said that the LVM took over the forests when their value was equal to zero and it was done without evaluation.

	LVM: The logical way to manage space (Site not responding. Last check: 2007-10-20)
		LVM is very close to the magic 1.0 release (it’s at 0.9), but you don’t have to wait for that version.
		LVM frees you from dilemmas like `Should I have a /home that is 5GB or should I make it 4GB and make a slightly larger /var partition?’ For whatever decision you take, most of the time, you either end up allocating more space than required or you find that future requirements have nullified your allocations.
		Now that you have the required LVM tools installed, add “vgscan” and “vgchange —-a y” to your startup files so that, the available volume groups are initialized and available at startup before the LVM-based filesystems are mounted.

	Petition to get LVM into the Linux kernel
		In order to facilitate this, we've opted to try to convince the supporters of LVM in the Linux kernel to sign a petition, which we then can present to Linus Torvalds, to show how people are indeed interested in seeing Linux finally have a LVM.
		LVM simply makes storage management much more flexible by allowing storage to be reallocated easily at any time.
		LVM is not a new concept and has been proven to be indispensible in other OSes, (ie.

	LVM 2 FAQ
		One possible cause of this is that some versions of LVM 1 (The user that reported this bug originally was using Mandrake 9.2, but it is not necessarily limited to that distribution) did not put a UUID into the PV and VG structures as they were supposed to.
		The most current versions of the LVM 2 tools automatically fill UUIDs in for the structures if they see they are missing, so you should grab a more current version and your problem should be solved.
		Upgrading to LVM 2 is a bit trickier with root on LVM, but it's not impossible.

	Common threads: Learning Linux LVM, Part 1
		Creating an LVM logical volume is really easy, and once it's created we can go ahead and put a filesystem on it, mount it, and start using the volume to store our files.
		The LVM system will then allocate storage from the volume group we specify and create our new volume, which is now ready for use.
		The LVM system ensures that our logical volumes continue to operate perfectly while allowing the administrator to physically change where everything is stored.

	The Software-RAID HOWTO: Partitioning RAID / LVM on RAID
		LVM has been in the stable Linux kernel series for a long time now - LVM2 in the 2.6 kernel series is a further improvement over the older LVM support from the 2.4 kernel series.
		While LVM has traditionally scared some people away because of its complexity, it really is something that an administrator could and should consider if he wishes to use more than a few filesystems on a server.
		Resizing of filesystems: LVM supports hot-resizing of volumes (with RAID devices resizing is difficult and time consuming - but if you run LVM on top of RAID, all you need in order to resize a filesystem is to resize the volume, not the underlying RAID device).

	RAID and Data Protection Solutions for Linux
		LVM implements a set of features and functions that resemble those that would be found in traditional LVM systems on other Unixes.
		The benefit of LVM is that you can add and remove hard drives, and move data from one hard drive to another without disrupting the system or other users.
		Thus, LVM is ideal for administering servers to which disks are constantly being added, removed or simply moved around to accommodate new users, new applications or just provide more space for the data.

	A Walkthrough of the LVM for Linux
		LEs are abstract chunks of storage mapped by the LVM to Physical Extents in a volume group.
		LVM will probably be integrated into future Linux kernels, but for now it must be added manually.
		Since LVM requires entire Physical Volumes to be assigned to Volume Groups, you must have a few empty partitions ready to be used by LVM.

	Linux Logical Volume Manager (LVM) on Software RAID
		If you used RAID 5, there wouldn't be any point in striping in LVM as you already would have that benefit (see Raid if you don't understand that).
		For a LVM volume group, one physical volume is enough.
		I think my next project will be to create a LVM for my main OS partition, and see what kind of speed I can get out of that.

		You have to change each LVM partition used to be of type 8e (Linux LVM).
		The LVM software effectively tricks the operating system into thinking the volume group is a new hard disk.

		For this, it's assumed you have an LVM and XFS volume running and "dm-snapshot" (the LVM kernel extension to permit snapshotting) loaded into the kernel.
		When you take the snapshot, you're essentially creating a new LVM device that appears to be a duplicate of the "real" filesystem at a point in time.
		To do this we create another LVM device (using lvcreate) with an argument of -s to indicate we want a snapshot and the -n argument to name it.

		If I can't repartition this, imaging the drive, reformatting, and restoring it later is an option, but one I'd prefer to avoid.
		Note that I've read the LVM howto and done some googling on my own, and haven't found satisfactory answers to my questions.

		It is reasonably backwards-compatible with the original LVM toolset.
		To use LVM2 you need 3 things: device-mapper in your kernel, the userspace device-mapper support library (libdevmapper) and the userspace LVM2 tools.
