| BOFS: Linux-HA BOFS |
| Alan L Robertson |
| project: http://www.linux-ha.org/ |
This talk was basically an overview of the current state of the Linux-HA project. I found it very interesting, in fact I won the hat for asking the most questions! ;-) But instead of repeating all that information here I'll just direct you to the project's website (see link).
Some quick notes regarding this talk include:
revision 1 of this project was meant and designed for a two-node high-availability configuration
the two nodes can communicate via any of a number of interfaces including: serial, UDP, mcast, bcast, ...
fail-overs occur on node failures, when there is a loss of connection
all of this project's code works in user-space, no kernel mods or drivers required
this project does not (not even in version 2) do database replication across the nodes of the system; however, there is this thing called DRBD (http://www.drbd.org/) [which is part of or comes from Linux-HA?] which is a block-level replication technology for 2 nodes only (think of it as RAID1 over LAN)
