Re: UM3 + different pools of services/realservers

Hi Nick.

Sorry for the late reply, I didn't get your problem the first time 
reading your mail.
Now I think I get it.
You simply want to configure multiple virtual services on one director pair?

If so, what you want to do is simply add more IPaddr2 lines in your 
haresources...
Like:

dir01.ece.utexas.edu \
        ldirectord::ldirectord.cf \
        LVSSyncDaemonSwap::master \
        IPaddr2::128.83.59.2/24/eth0/128.83.59.255 \
        IPaddr2::128.83.59.3/24/eth0/128.83.59.255 \
        IPaddr2::128.83.59.4/24/eth0/128.83.59.255 

Be carefull with the \ at the end of the line and start the line with a tab...

Hearbeat identifies the diffrent cluster-resources with the first line in the
haresources config. In the example above the line:
        ldirectord::ldirectord.cf \

This implies that if you want to have many diffrent resource-groups this first line must be diffrent for each group
(an good idea is to have for example an IPaddr2-line first since you probably will have diffrent IPaddresses to you resource groups...)


Anyway, in you case I think you would like to have only one group with many IPaddr2 line...
No need to try to start ldirectord many times is it...?
And of course in ldirectord.cd you have _all_ your services defined...
