For each cluster, two files named \fIcluster\fB.instances\fR and
24
\fIcluster\fB.nodes\fR will be generated holding the instance and node
25
data. These files can then be used in \fBhbal\fR(1) or \fBhspace\fR(1)
26
via the \fB-i\fR and \fB-n\fR options. In case the cluster name

For each cluster, one file named \fIcluster\fB.data\ will be generated

\fBhbal\fR(1) or \fBhspace\fR(1) via the \fB-t\fR option. In case the

cluster name contains slashes (as it can happen when the cluster is a

fully-specified URL), these will be replaced with underscores.

The program does not check its input data for consistency, and aborts

with cryptic errors messages in this case.

The RAPI collection doesn't deal with non\(hy\fBdrbd\fR instances, and

chokes on input data which has such instances.
