logical volume

In this posting i’ll touch on only ext3 since that’s the default fs. Later, I’ll touch others if it’s requested.

There are a few steps you have to take to resize a partition. First, you have to resize the filesystem (be sure to do this before you reduce the lv, as that could cause data loss).

I made a couple of scripts to make it easier to provision a series of Ubuntu guests based on a LVM logical volume with a base image.

The provisioning script creates a snapshot of this base image, mounts and modifies essential files directly on the guest filesystem, and creates an init-script in /etc/init.d.

haad-dm: Import of the device-mapper driver. This driver is a BSD rewrite of the linux dm driver. For now only error, linear and zero targets are supported.

This driver uses NetBSD specific ioctls based on proplib. Adam Hamsik was able to create a logical volume (with lvm2tools lvcreate utility) with this version of the driver, newfs it and mount it.

ddb: Add a show files command that prints the vnodes associated with a given struct proc and, if LOCKDEBUG is built in, the lock status of the uvmobject.
