For each cluster, two files named \fIcluster\fB.instances\fR and |
|
24 |
\fIcluster\fB.nodes\fR will be generated holding the instance and node |
|

data. These files can then be used in \fBhbal\fR(1) or \fBhspace\fR(1) |
|

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 |

holding the node and instance data. This file can then be used in |

\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 |

The program does not check its input data for consistency, and aborts |
101 | 100 |
with cryptic errors messages in this case. |

The RAPI collection doesn't deal with non\(hy\fBdrbd\fR instances, and |
|
104 |
chokes on input data which has such instances. |
