Hi,
can anyone try to explain how can I modify this existing cib.xml to
obtain a configuration where:
- Apache is started only in the node where drbd is master;
- Apache is started after the filesystem is mounted;
I guess I have to insert two more constraints:
1. order to start apache after filesystem is mounted;
2. location to start apache only where drbd is started;
Cib.xml follows:
<cib admin_epoch="0" epoch="7" num_updates="1" generated="false"
have_quorum="false" ignore_dtd="false" num_peers="0"
cib_feature_revision="2.0" cib-last-written="Wed Oct 17 21:35:48 2007">
