LACP, or Link Aggregation Control Protocol, is a standard defined by IEEE 802.3ad for bundling or bonding multiple physical network ports together into one virtual device. This provides both high availability and load balancing. Participants in an LACP aggregation actively communicate with each other using LACPDUs every 1 second or 30 second to maintain knowledge of the bond configuration.

LACP with VMWare 5.1 Distributed Switches (VDS) over multiple hosts.. How many switch LACP groups?
I'm setting up a 2-host VMWare 5.1 Cluster to use a vDS (Virtual Distributed Switch) with LACP enabled, over 4 NICs (2 per host).
In times past, when I've used VMWare Standard Switches with Static LAGs, each host got their own LAG Group on the…

I've built an NFS cluster with OCFS2 as a backing filesystem.
This is working quite well with the exception of when a node is restarted/shutdown cleanly it causes a fence operation as network is severed before unmounting OCFS2 filesytems to inform…
