先にお知らせしていますように，KAGRA主データシステムの System-A(kagra-gw-0[12], m31-0[01], など) は，来たる11月30日をもって，停止し撤去されます。それ以降は，System-A のユーザー・ホームディレクトリを含む全てのファイルにアクセスできなくなります。
KAGRAデータは，全てSystem-Bにコピーされれていますが，ユーザーのホームディレクトは，こちら側でコピーしませんので，必要なファイルは，各自でSystem-B，または手元の装置等にコピーしてください。
System-AからSystem-Bにファイルをコピーする方法については，"KAGRA Main Data System Startup Guide"
