This document is not intended to be a tutorial on howto create ha-cluster |
| 50 |
using heartbeat. It serves as a supplement to recent >=sys-cluster/heartbeat-3.0 |
| 51 |
unmasking. |

Please be aware that new Pacemaker also supports OpenAIS/Corosync cluster infrastructure besides Heartbeat, and the former is being preferred solution by the upstream. |

Shutdown one of your nodes. This keeps the cluster working while we prepare the migration. |
| 72 |
</p> |
| 73 |
|
| 74 |
<p> |
| 75 |
Heartbeat-2.x was using the user <c>cluster</c> and group <c>cluster</c> for |
| 76 |
its file permissions. Cluster-glue/Pacemaker now uses the user <c>hacluster</c> and |
| 77 |
group <c>haclient</c>, so we'll have to migrate them to ensure the owner user/group |
| 78 |
on the used directories remain correct. |
| 79 |
</p> |
| 80 |
|
| 81 |
<p> |
| 82 |
Rename user <c>cluster</c> to <c>hacluster</c>. |
| 83 |
</p> |
| 84 |
<pre caption="Renaming user"> |
| 85 |
# <i>usermod -l hacluster cluster</i> |
| 86 |
</pre> |
| 87 |
|
| 88 |
<p> |
| 89 |
Rename group <c>cluster</c> to <c>haclient</c>. |
| 90 |
</p> |
| 91 |
<pre caption="Renaming user"> |
| 92 |
# <i>groupmod -n haclient cluster</i> |
| 93 |
</pre> |
| 94 |
|
| 95 |
<p> |
| 96 |
Adjust the permissions/rights of the folders used by heartbeat. |
| 97 |
</p> |
| 98 |
<pre caption="Fix folder permissions"> |
| 99 |
# <i>chown -R hacluster:haclient /var/lib/pengine</i> |
| 100 |
# <i>chown -R hacluster:haclient /var/lib/heartbeat/*</i> |
| 101 |
# <i>chown -R hacluster:haclient /var/run/crm</i> |
| 102 |
</pre> |
| 103 |
<note> |
| 104 |
You may not have all of those folders, as their existence depends on your USE flags and version of heartbeat. |

<p>Emerge pacemaker with heartbeat support.</p> |
| 115 |
<pre caption="Emerging pacemaker"> |
| 116 |
# <i>echo "sys-cluster/pacemaker -ais heartbeat" >> /etc/portage/package.use</i> |
| 117 |
# <i>emerge pacemaker</i> |
| 118 |
</pre> |
| 119 |
|
| 120 |
<p> |
| 121 |
Export your current haresource file to a CIB formatted xml. |
| 122 |
</p> |
| 123 |
|
| 124 |
<pre caption="Exporting haresource file"> |
| 125 |
# <i>cd /etc/ha.d</i> |
| 126 |
# <i>/usr/lib/heartbeat/haresources2cib.py --stdout > import.xml</i> |
| 127 |
</pre> |
| 128 |
|
| 129 |
<p> |
| 130 |
Now there are two possibilities depending on whether or not you were running heartbeat-2.x with crm. Check <c>crm on/off</c> in <path>/etc/ha.d/ha.cf</path>. |
| 131 |

<p> |
| 141 |
You can safely start heartbeat-3.x. |
| 142 |
</p> |
| 143 |
<pre caption="Run heartbeat"> |
| 144 |
# <i>/etc/init.d/heartbeat start</i> |
| 145 |
</pre> |
| 146 |
|
| 147 |
<p> |
| 148 |
Now, import your resources from previously exported CIB. |
| 149 |
</p> |
| 150 |
<pre caption="Import resources"> |
| 151 |
# <i>cibadmin --replace --obj_type resources --xml_file import.xml</i> |
| 152 |
</pre> |

<title>You were NOT using crm</title> |
| 158 |
<body> |
| 159 |
<p> |
| 160 |
Use <path>import.xml</path> as the actual CIB of heartbeat-3.x. |
| 161 |
</p> |
| 162 |
<pre caption="Import resources"> |
| 163 |
# <i>cp import.xml /var/lib/heartbeat/crm/cib.xml</i> |
| 164 |
# <i>chown hacluster:root /var/lib/heartbeat/crm/cib.xml</i> |
