LVM multipath support patches


2002-10-24 LVM multipath support v7 for lvm 1.0.5 - experimental (superseded)

If you download any software from this web site please be aware of the Warranty Disclaimer and Limitation of Liabilities.

This patch enables LVM (logical volume manager) to support disk devices that can be accessed through more than one data path. For example this could be storage subsystems that can be connected to more than one controller or that are integrated into storage area networks (SANs). Normally these would be seen in Linux as multiple block devices with identical contents that can be accessed independently.

With the patch applied LVM can spread IO over available paths (load balancing) or automatically re-route data to remaining paths should some of the paths fail (failover support). In order to get this working you will need the original LVM package (currently version 1.0.5) from Sistina at:

There you also find information about what LVM is and how to use it. Then you get the multipath patch package from this page and proceed as described in the readme file that is included in the package.
For usage of "Multipathing support" see Linux for zSeries and S/390 Device Drivers and Installation Commands.
