Нагуглил похожую проблему, там предлагалось удалить /var/lib/docker/, однако, это не помогло. Смещает вот это - can’t list qgroups: quotas not enabled, но что с этим делать не ясно.
В WindowsToGo есть функция Drive removal detection, которая позволяет при случайном выдёргивании флешки с ней подождать 60 секунд и продолжить работу, если флешку обратно вставят.
А Linux так может? Долго думал, но кроме скрипта, который при помощи kexec перезапустит систему снова с флешки, ничего не придумал. Как в Linux заморозить всё I/O, предназначенное устройству, а потом применить его на другое устройство? Программу, которая будет это делать, можно удержать в памяти при помощи memlockd.
В свете выхода ownCloud 5.0 и его недостатков, подумалось тут — а нет ли в природе готового приличного фронтенда к файловой системе? Чтобы можно было приватно и с возможность расшарить порыться в файлах на файловой системе через браузер в цивильном вебдванольном исполнении? Со всякими эффектами для фоток, прослушиванием музыки и т.п.? Чтобы можно было давать описания файлов, опционально — генерировать превьюшки для RAW и т.п.?
Понятно, что такое и самому пишется максимум за несколько дней плотной работы и у меня давно в планах стоит, но, вдруг кто-то уже такое делал?
