Red Hat Cluster: CentOS 5.1上でRHCSを使ってみる・予告編

今まで、CentOS上でRed Hat Cluster Suiteを使うべく検証を行ってきた(タグRHCS参照)。結果、CentOS 5.0上ではいろんな問題が見つかったが、CentOS 5.1ではかなり解決されている。まずは、この検証結果を簡単に。

さて、CentOS 5.0上での問題は、このブログでも指摘してきた。

1. /etc/redhat-release問題(参考: [1])
2. kmod-gfs問題(参考: [2])

これらの問題が、CentOS 5.1で解決されていることを確認した。

前者は、Congaがクラスタメンバの/etc/redhat-releaseを参照してクラスタメンバ間でバージョンに差異が無いことをチェックするのだが、これが、CentOSのデフォルトのままではダメで、RHEL5だ、と詐称せねばならない、と言う問題。実際にCentOS 5.1をインストールしてLuciから詐称せずにクラスタを構成できる。

後者は、クラスタメンバを再起動したり、フェンスしたりを繰り返すと、ノードの起動に時間がかかったり、シャットダウン不能になったりすると言う問題。これも、実際にCentOS 5.1上でクラスタを構成してみると、発生しないようだ。

なお、『CentOS 5.0からCentOS 5.1へアップグレードする』および『CentOS 5.0からCentOS 5.1へアップグレードする・補足』で指摘した通り、CentOS 5.0を使っていても、yum updateしていれば、CentOS 5.1相当に更新される。

追記(2008/2/24):
検証を再開した。

CentOS 5.0からCentOS 5.1へアップグレードする・補足

前のエントリで、

ファイル/etc/redhat-releaseの中身は、

CentOS release 5 (Final)

のままで変化がなかった(ホンマにこれでエエんかいな？)。

と書いた。

調べてみると、/etc/redhat-releaseはcentos-releaseというパッケージに含まれている。CentOS 5.1では、このパッケージのバージョンは、5-1.0.el5.centos.1。このパッケージを実際に展開してみると、

$ ls
centos-release-5-1.0.el5.centos.1.i386.rpm
$ rpm2cpio centos-release-5-1.0.el5.centos.1.i386.rpm | cpio -id
75 blocks
$ cat etc/redhat-release
CentOS release 5 (Final)
$

ということで、「CentOS release 5」のまま変化しないのが正しいようだ。

レポジトリを調べてみると、ディレクトリ5.0および5.1が存在していて、5が5.1へのシンボリックリンクになっている様に見える。
なので、CentOS 5.0も、普通にyum updateすれば、自然に5.1へアップグレードしている、と言うことになる。

CentOS 5.0からCentOS 5.1へアップグレードする

「RHEL 5.1リリース! CentOS 5.1も近日中に」で紹介したCentOS5.1がついにリリースされた。ということで、Xen DomU上のCentOS 5(CentOS5.0)ををCentOS 5.1へアップグレード(バージョンアップ)してみた(こんなときには、VLMのスナップショット機能とXenの組合が便利だ)。

2008/7/7追記:
『CentOS 5.1からCentOS 5.2へアップグレードする』を公開した。

手順は簡単で、単に

# yum update

とするだけ(手間を省くため、-yオプションを付けてyum -y updateとしてもいい)。
ただ、手元の環境で実際に作業を行ってみると、halパッケージが欠損していて、これを除外する必要があった。

# yum --exclude=hal update

これは、ミラーリングの時間差の問題で、時間が解決する問題だと思われる。
LVMを認識する際に警告が出ている。特に問題はないようだ。
ファイル/etc/redhat-releaseの中身は、

CentOS release 5 (Final)

のままで変化がなかった(ホンマにこれでエエんかいな？)(2007/12/10(月): これに関して追記した)。
作業ログは、記事の最後を参照。

なお、リリースノートによると、CentOS 5.1では、以前『Red Hat Cluster: 予告編+x』で報告した、/etc/redhat-releaseを修正しなければCongaが正常に動作しない、という問題が解決されたそうだ。
しかし一方、

仮想化ソフトウェア(Xenなど)を使用すると、libvirtパッケージがインストールされます。このパッケージはCentOS5.1以来、 dnsmasqパッケージと依存があります。(dnsmasqは軽量のDNSとDHCPサーバです)。他のDNSかDHCPデーモンにも同じシステムで動かせのであれば、あなたは、dnsmasqがそれらの動作を妨げないことを確認する必要があります。

という記述もあり、Xenを使用している場合には注意が必要だ。
