Ich verwende Flocker, um Andockcontainerdaten über das ZfS-Dataset-Backend zu persistieren und zu migrieren.Flocker-Datenmigration
docker run -v test:/data --volume-driver flocker busybox
sh -c "echo hello world > /data/file.txt"
Ich hatte diesen Fehler für eine Woche:
Unable to find image 'busybox:latest' locally latest: Pulling from library/busybox 583635769552: Pull complete b175bcb79023: Pull complete Digest: sha256:c1bc9b4bffe665bf014a305cc6cf3bca0e6effeb69d681d7a208ce741dad58e0 Status: Downloaded newer image for busybox:latest Error response from daemon: Cannot start container 128ddff1c0e9d6740c23b2f475b14206775a131878b4ed725a3280e22de79666: Timed out waiting for dataset to mount...
Jede Hilfe würde geschätzt.

Hey DIStephane, Wie hast du diese Log-Dateien? Ich kann diese Protokolle nicht abrufen. –
Sie können Protokolle im Verzeichnis/var/log/flocker finden. – DiStephane
Ich benutze centos7.2 und kein solches Verzeichnis ist da. –
