problems getting virtual IP for mysql-cluster guide

[abubin]

Hi,

I am trying to setup mysql-cluster on ubuntu 10.04 running vmware.

I followed the guides in http://www.howtoforge.com/loadbalanc...cluster_debian

However, since ultramonkey does not work with ubuntu 10.04, I had to install the packages manually.

apt-get install ipvsadm ldirectord heartbeat

I am getting difficulty getting the virtual IP on my loadbalance servers.

In the log, I found some error that LVSSyncDaemonSwap is not loaded. Then I checked and found this file is not located in the folder where it should reside.

Further checking, it was said newer kernel do not need this LVSSyncDaemonSwap anymore. Probably the reason why this file was not installed with ldirectord? Or is this an ultramonkey related file?

I tried removing LVSSyncDaemonSwap entry in my /etc/ha.d/haresources file but still no go.

Anyone can shed some light?

Hi,

I also have the same problem!

The problem is that the file not exist when install the packet LVSSyncDaemonSwap. Copy the down text and generate file in /etc/ha.d/resources.d/LVSSyncDaemonSwap
The file is here:
