The [[Linux]] Logical Volume Manager, is commonly abreviated to LVM. Although LVM can used for other [http://en.wikipedia.org/wiki/Logical_Volume_Management Logical Volume Management] variants as well.

Plaso (plaso langar að safna öllu) is the Python based back-end engine used by tools such as log2timeline for automatic creation of a super timelines. The goal of log2timeline (and thus plaso) is to provide a single tool that can parse various log files and forensic artifacts from computers and related systems, such as network equipment to produce a single correlated timeline. This timeline can then be easily analysed by forensic investigators/analysts, speeding up investigations by correlating the vast amount of information found on an average computer system. Plaso is intended to be applied for creating super timelines but also supports creating [http://blog.kiddaland.net/2013/02/targeted-timelines-part-i.html targeted timelines].
  
Not all forensic tools have support for Linux Logical Volume Manager (LVM) volumes, but most modern Linux distributions do.

The Plaso project site also provides [[4n6time]], formerly "l2t_Review", which is a cross-platform forensic tool for timeline creation and review by [[David Nides]].
  
== Mounting an LVM from an image ==
+
== Supported Formats ==
If you have an image mount the LVM read-only on a loopback device (e.g. /dev/loop1) by:
+
<pre>
+
sudo losetup -r -o $OFFSET /dev/loop1 image.raw
+
</pre>
+
  
Note that the offset is in bytes.
+
=== Storage Media Image File Formats ===
 +
Storage Medis Image File Format support is provided by [[dfvfs]].
  
If you need to write to the image, e.g. for recovery, use [[xmount]] to write the changes to a [[shadow file]] (or cachefile in xmount terminology).
+
=== Volume System Formats ===
<pre>
+
Volume System Format support is provided by [[dfvfs]].
sudo xmount --in dd --cache sda.shadow sda.raw image/
+
</pre>
+
  
You can then safely mount the LVM in read-write mode (just omit the -r in the previous losetup command).

Plaso (plaso langar að safna öllu) is the Python based back-end engine used by tools such as log2timeline for automatic creation of a super timelines. The goal of log2timeline (and thus plaso) is to provide a single tool that can parse various log files and forensic artifacts from computers and related systems, such as network equipment to produce a single correlated timeline. This timeline can then be easily analysed by forensic investigators/analysts, speeding up investigations by correlating the vast amount of information found on an average computer system. Plaso is intended to be applied for creating super timelines but also supports creating targeted timelines.

The Plaso project site also provides 4n6time, formerly "l2t_Review", which is a cross-platform forensic tool for timeline creation and review by David Nides.
