I've got a slightly different approach to load balancing here, its more for maintenance and high-availability at the application rather than at the physical host.

Say I have 2 web services, which I deploy to 2 web servers. So far, its easy to set up HAProxy to load-balance between them, and to direct traffic to either host. What I'd like to do is to be able to stop 1 of the web services on a host, which should make the LB direct calls to the other host, without affecting the other web service.

So I would stop WS1 on Host1, and the LB would direct traffic to WS1 running on Host2, but WS2 would still be running on both hosts.

I may be going bonkers here, but I'm trying to move a directory to a new location, overwriting the contents (on Linux, using bash).

Everytime I try it, it responds with "mv: cannot move `./src' to a subdirectory of itself"

eg. I have:

/src
/new/dir/src
/$ mv src/ new/dir/

If I delete the destination dir, then it works. I know I can move the contents of the source dir to overwrite the destination, but I'd like to use the same command to overwrite the destination if it already exists, or move the source if it doesn't.

In a comment to my response to this question , cop1152 said he loved WMI scripts. Well, so do I!

What are your favourite, best, most useful scripts you'd like to share with the community?

thanks.
