WSUSにアップデートを追加しすぎて動かなくなってしまったでござる

Posted at

WSUSは使っているうちにディスク容量を圧迫してしまう。いろいろと情報を入手していくうちに，不要なアップデートを"拒否"した上でクリーンアップをかければ改善されるとのこと。

これをした結果ディスク容量が1.5TBほど削減された。と，ここまでは良かったのだが，調子にのってしまった。これだけディスクが空くなら，全てのアップデートを反映させても大丈夫なのではないかと，ドライバーやドライバーセットも含めて同期をかけてしまった。

その結果何が起こったかというと，データベースからアップデートを取り出すのにタイムアウトで取り出せなくなってしまったのだ。単にドライバーやドライバーセットのチェックボックスを外しても既に同期sたアップデートがデータベースから消えるわけではなく，また，これらを消す方法がなかなか見当たらない。かろうじて，見つけた情報ソースがこれ。

newquery.sql
SELECT UpdateTypeID FROM tbUpdateType WHERE Name = 'Driver'
GO

DriverのUpdateTypeID がD2CB599A-FA9F-4AE9-B346-94AD54EE0629と分かったところで，

として，データベースから削除!(相当時間がかかった)

何かエラーは出るけれども，そのままインデックスの再構築

念のため，最後にクリーンアップ。これでデータベースからドライバーのレコードは消え去りました。

ただ，コンピュータのインストール済みの%の数字が更新されてくれないのだが，これはコンピュータを削除して，追加しなおせばいいのだろうか...?
