Topic: Logical Volume Management (LVM)

[Jeff Peters]

I have three IDE drives of various capacity and would like to know if anyone has had success setting up LVM on their SME server (any version.)

The 6.0 beta 3 version that I current have has the required kernel to accept LVM and I know that you would have to install and/or compile several additional software to include but not limited to Pvcreate etc.

Any attempts? Horror stories?

In brief for those who have never heard of KVM, the following describes it from
   
    http://tldp.org/HOWTO/LVM-HOWTO/c72.html


"Logical volume management provides a higher-level view of the disk storage on a computer system than the traditional view of disks and partitions. This gives the system administrator much more flexibility in allocating storage to applications and users.

Storage volumes created under the control of the logical volume manager can be resized and moved around almost at will, although this may need some upgrading of file system tools.

The logical volume manager also allows management of storage volumes in user-defined groups, allowing the system administrator to deal with sensibly named volume groups such as "development" and "sales" rather than physical disk names such as "sda" and "sdb".

Logical volume management is traditionally associated with large installations containing many disks but it is equally suited to small systems with a single disk or maybe two."


Thanks in advance.
