ペースメーカーcorosyncelsbリソーススクリプト（SybaseデータベースASEサーバーおよびバックアップサーバー）

Rhel7.2でpcsを使用してlsbリソースを作成しようとしています。「sybase」スクリプトは、Sybase DatabaseASEサーバーとバックアップサーバーの起動と停止と再起動$ステータススクリプトに関するものです。

そこで、 付録G. InitスクリプトLSBコンプライアンス で詳しく説明されている手順に従って、sybaseスクリプトを確認しました。

これらの手順の項目5をテストしたところ、出力された結果は0でした。

ステータス（停止）：

/etc/init.d/some_service status;エコー「結果：$？」

私の質問：

  • スクリプトはコマンドを受け入れましたか？
  • スクリプトは、サービスが実行されていなかったことを示しましたか？
  • コマンドは結果を出力しました：3（通常の出力に加えて）？
  • どうすれば修正できますか？

問題を解決する方法について何か提案はありますか？

の結果 pcs resource show ase157_resはop start timeout="20s"？

「/etc/init.d/that_scriptstart」まで30秒かかるので、timeout=はそれ以上でなければなりません。

スクリプトのステータス関数にexit 3を追加して、準拠させようとしましたか？

このようなものが機能するはずです：

# Check Sybase Adaptive Server and Backup Server status
status() {
  dataserver=$(pidof dataserver)
  backupserver=$(pidof backupserver)
  if [ -n "$dataserver" ]; then
      echo "sybase Adaptive Server is running!" && exit 0 || exit $?
  else
      echo "sybase Adaptive Server is stopped!"
      exit 3
  fi

  if [ -n "$backupserver" ]; then     
      echo "sybase Backup Server is running!" && exit 0 || exit $?
  else
      echo "sybase Backup Server is stopped!"
      exit 1
  fi
}

EDIT：失敗したアクションは開始操作に対するものでした。スクリプトで何が失敗しているのかをデバッグしようとすると、「ロガー」コマンドをスローし始め、ログを見て失敗が発生している場所と理由をデバッグできるようにします。

このようなもの：

# Start sybase Adaptive Server and Backup Server
start() {
  logger "DEBUG: ENTERED START FUNCTION
  SYBASE_ASE_START=$"Starting ${NAME} Adaptive Server: "
  $SU sybase -c ". $SYBASE/SYBASE.sh; $SYBASE/$SYBASE_ASE/install/startserver \
-f $SYBASE/$SYBASE_ASE/install/RUN_${SERVER} > /dev/null"
  ret=$?
  logger "DEBUG: RETURN CODE: $ret"
  logger "DEBUG: CHECK THE VARS:"
  logger "DEBUG: \$SU=$SU"
  logger "DEBUG: \$SYBASE/SYBASE.sh=$SYBASE/SYBASE.sh"
  logger "DEBUG: \$SYBASE_ASE=$SYBASE_ASE"
  logger "DEBUG: \${SERVER}=${SERVER}"
  if [ $ret -eq 0 ]
  then
      echo -n "$SYBASE_ASE_START                    ["
      echo -n -e "\033[32m Success \033[0m"
      echo "]"
      logger "DEBUG: We're about to leave \$ret -eq 0"
  else
      echo -n "$SYBASE_ASE_START           ["
      echo -n -e "\033[31m Failed \033[0m"
      echo "]"
      logger "DEBUG: We're about to leave \$ret -ne 0"
                exit 1
  fi

次に、ログ（/ var/log/messagesまたは/ var/log/syslog）を調べ、「DEBUG」メッセージを探して、スクリプトのどこで問題が発生しているかを判断します。
