[ClusterLabs] Adding HAProxy as a Resource

Tue Jul 30 05:39:52 EDT 2019

Hi ,

I am compiling and installing the server on EL 7 server. Also I tried once again with systemd-devel and dbus-devel installed , but still I am unable to use system resources.

Is there any other dependency that I have to install.

With Regards
Somanath Thilak J

In that case, it will check whether the build machine has everything needed to support systemd. The main requirement is that the systemd and dbus development libraries (systemd-devel and dbus-devel) are available.
