Real HA cluster implementation

[alexskynet]

And now multi active server environment!

Restarting daemons (bind-httpd) is a clue in multi active server environment.

I plan to use iNotify to have some "flag files" written in a given share point

Cron jobs will check for those files on every node in the cluster and if present, will restart/reload daemons and then remove the flag files.

Only one ispcp_daemon will run at a time.

IPs will be natted, and for now I'll simply change the relevant templates for bind and httpd

The balancers will provide automatic cluster addiction/subtraction of nodes in a completey automated way (new nodes will have to be added to a configuration file, but stopping a node will cause traffic migration on superstit nodes)

See you soon

Is this patch based on the current stable release?

Did you use a script to import all your existing ispcp system users into the new tables and then remove them from the shadow/passwd/group files? If so, can you share?

Hi

yes the patch is on 1.0.5

No: to me it was a completely new installation so I didn't have to import users.

I guess it can be done using a script in PHP or Perl

Best regards
