Unlike most HOWTOs, Linux-HA HOWTO is really more of a guide for implementers of
HA technology for Linux than it is for people who just want to install it. It
was written by someone who had a lot of IBM experience (as you might guess).
For the last year and a half, we have been implementing a few of the ideas in
the Linux-HA HOWTO, plus a few not mentioned in it. The project is picking up
speed quite rapidly at this point.
At this point, we are focusing much more on low-end hardware than high-end
hardware. And yes, disk mirroring across the network is on our list of things
to do. It should come up to be done pretty soon now. I am still hoping we have
a preliminary version available by the end of this year.
If you want to understand current implementation efforts, the Linux-HA home page
might be a good resource for you. Recent progress is documented in the TODO
list pointed to by that page.
You can find this information here:
There is also a development list for Linux-HA work. Info on it can be found
