Heartbeatでquotaを使う

Heartbeatで動的にマウントしたファイルシステムでquotaを使うには、ちょっとした工夫が必要です。

1. /etc/ha.d/resource.d/Quota を作成します。
私はネットから拾ってきたものをそのまま使いました。

2. /etc/ha.d/resource.d/Quotaに実行権限を付与します。

# chmod +x /etc/ha.d/resource.d/Quota

3. /var/lib/heartbeat/crm/cib.xml の～の中に設定を追加します。
クラスタが動作中の場合、/tmp/cib.xmlに編集済みのファイルを置いて"cibadmin -U -x /tmp/cib.xml"で更新した方が楽です。
※パラメータ(name="1"～"4")は適宜変えてください。

<primitive class="heartbeat" id="Quota" provider="heartbeat" type="Quota">

<instance_attributes id="Quota_inst_attr">

<attributes>

<nvpair id="Quota_attr_1" name="1" value="y"/>

<nvpair id="Quota_attr_2" name="2" value="y"/>

<nvpair id="Quota_attr_3" name="3" value="y"/>

<nvpair id="Quota_attr_4" name="4" value="/work"/>

</attributes>

</instance_attributes>

</primitive>
