※　IBM Bluemix(SoftLayer) のベアメタルサーバで NIC を冗長化した場合、
「NIC 1 (eth0)」と「NIC 3 (eth2)」、「NIC 2 (eth1)」と「NIC 4 (eth3)」が LAG で束ねられています。
※　本手順書では、LAG の設定がない前提としますが、LAG 対応させるための設定方法は注記しておきます。
※　IBM Bluemix(SoftLayer) の仮想サーバは、ベアメタルサーバと比較して、主に以下の相違点があります。
・「NIC 3」と「NIC 4」を追加できません。
・MTU は 1500 までしかサポートされません。
・ローカルストレージのデバイス名が異なります。

Additional messages may also appear here depending on any configured debug and trace settings
By default Pacemaker will inherit the logfile specified in corosync.conf
PCMK_logfile=/var/log/pacemaker.log

Use 'none' to disable - not recommended

#
#
#
#
Send all messages up-to-and-including the configured priority to syslog
A value of 'info' will be far too verbose for most installations and 'debug' is almost certain to send you blind
The default value is 'notice'
PCMK_logpriority=emerg|alert|crit|error|warning|notice|info|debug
# Log all messages from a comma-separated list of functions
# PCMK_trace_functions=function1,function2,function3
# Log all messages from a comma-separated list of files (no path)
# Supports wildcards eg. PCMK_trace_files=prefix*.c
# PCMK_trace_files=file.c,other.h
# Log all messages matching comma-separated list of formats
# PCMK_trace_formats="Sent delete %d"
# Log all messages from a comma-separated list of tags
# PCMK_trace_tags=tag1,tag2
# Dump the blackbox whenever the message at function and line is printed

#
#
#
#
#
#
#
#
#
Enable blackbox logging globally or per-subsystem
The blackbox contains a rolling buffer of all logs (including info+debug+trace)
and is written after a crash, assertion failure and/or when SIGTRAP is received
The blackbox recorder can also be enabled for Pacemaker daemons at runtime by
sending SIGUSR1 (or SIGTRAP), and disabled by sending SIGUSR2
Multiple subsystems may me listed separated by commas
eg. PCMK_blackbox=crmd,pengine

当文書で紹介した構成で初期構築をご希望の方は、メール(mailto: [email protected])にてお問い合わせください。
リモートアクセスによる構築サービスを、弊社提示のヒアリング事項（当文書の緑色で記載した部分）以外のカスタマイズはなしとの前提で、
サーバ1台あたり10万円（税別）という超特価にてご提供中です。
1号機と2号機(Active 機と Stand-by 機)サーバの物理構成は同一構成との前提です。
カスタマイズやドキュメントの提供、個別訪問等は、別途ご相談となります。
クラスタの起動停止、スイッチオーバ(手動フェイルオーバ)以外の動作確認、結合試験、障害試験、性能試験等は、別途ご相談となります。
インストールメディアからインストールできない環境やコンソールにリモートアクセスできない環境でのインストールも別途ご相談となります。
監視設定（障害監視、リソース監視、セキュリティ監視等）については、別途ご相談となります。
UEFI 対応、ハードウェア固有のドライバや管理ソフト等のインストールについては、別途ご相談となります。
当該サーバには、消失したら困るデータは存在していない前提での作業となります。
既に動いている CentOS を置き換えるインストールの場合、ヒアリング事項を弊社で調査して提示することも可能です。
例えば、IBM Bluemix(SoftLayer) のベアメタルサーバの場合、CentOS7をあらかじめインストールした状態で弊社へお引き渡し頂ければ、
お客様の手間を省くことができます。
弊社での正式サポートは、お客様が当該サーバ用の Oracle Linux サブスクリプションを契約中か NRI OpenStandia に相談窓口をお持ちで、
代理で問い合わせを行うという前提を取らさせていただくことになります。費用はご相談ください。
サーバの調達・CE作業費用、OS 等のライセンス費用、サブスクリプション費用等はすべて別料金となります。
OS を Oracle Linux (UEK カーネル) に置き換えずに、RHEL・CentOS で構築することも可能ですが、制限事項についてご相談ください。
MySQL や PostgreSQL、Oracle の冗長構成構築サービスも鋭意開発中です。商品開発に関するリクエストがあればお知らせください。
検討させていただきます。
貴社のアプリケーション、サービス等を冗長化する共同開発も承ります。
