再起動前に特に特別な作業は行っていない

発生している問題・エラーメッセージ

Error:
Web application could not be started
Error ID:
9a63c4a7
Details:
It looks like Bundler could not find a gem. Maybe you didn't install all the gems that this application needs. To install your gems, please run:

bundle install
If that didn't work, then the problem is probably caused by your application being run under a different environment than it's supposed to. Please check the following:

Is this app supposed to be run as the daemon user?
Is this app being run on the correct Ruby interpreter? Below you will see which Ruby interpreter Phusion Passenger attempted to use.
-------- The exception is as follows: -------

試したこと

その後、再起動等はしても変化無し

Answer 1

エラーメッセージで、

Could not find nokogiri-1.8.1

と言われています。

再起動の直前だけでなく、前回redmine の起動に成功してから、今回再起動して失敗するまでの間に何か変更した内容はありませんか？

また、エラーメッセージに対応しなければならない内容が記載されていますが、エラーメッセージを読んで指示された内容を実行してみましたか？
その際に何かメッセージは出ましたか？　メッセージが出たのであれば、表示された内容を質問に追記してください。

Answer 2

完全にインフラ障害で自己解決しました

■原因
AWSのEBSバリュー無のUUIDが同じものが２つ作成されており、再起動時にルートボリュームに想定外のEBS(過去データボリューム)がアタッチされたため

お騒がせしました
