Откуда появляются 8Гб дискового пространства?

25.02.2015 15:07 · отредактировано #415696

Я загрузил live cd CentOS-7 с флешки размером 1 Гб . Винчестера нет. Память 4 Гб.

Откуда берутся эти 8 Гб live , если реально имеется лишь 4 Гб ОП + 1 Гб флешки= 5 Гб ?

kerogaz, :) Ниоткуда. Просто для установки на диск нужны будут 8Гб свободного места.

Wolfenberg, какие 8 GiB для установки? Просто у ТСа есть еще что-то, помимо флешки. ТС, подробнее.

судя по всему это какой-то виртуальный диск, squashfs, или даже unionfs/aufs.

размер явно фейковый:

(это _ровно_ 2²⁴).

А судя по тому что он в /dev/mapper/ , он еще както связан с lvm. O_o

Наверное это какая-то утилита которая сжимает информацию, делая тем самым видимость увеличения размера дискового пространства. Я помню когда были маленькие винчестера в 40 мб с помощью утилиты можно было увеличить его виртуальный размер до 80 Мб. Оочень давно знакомый привез из Германии компьютер, с винчестером 40 мб, а он виделся как 80 мб, я долго тогда репу чесал пока не отформатировал винчестер, утилита стёрлась, и стал виден реальный размер 40 мб.,за что получил втык. Пришлось убеждать товарища что хоть дисковый объем и уменьшился(вернее стал реальным) зато быстродействие увеличилось, за счет отсутствия процесса компрессии-декомпрессии файлов :) Я понял тогда что и немцы тоже непрочь развести лохов : продать 40 мб винчестер как 80 мб

Бред. Почитайте как сделать live дистр.

Squashfs на лив-сд - сжимающая файловая система.

26.02.2015 17:29 #415817

В свое время была DOS'овая утилитка DriveSpace, которая представляла собой драйвер сжатого тома, работавших поверх файловой системы и предоставлявших прозрачный механизм сжатия данных на лету. На уровне BIOS сжатый раздел (том) не увидишь же.

Squashfs (.sfs) — сжимающая файловая система для GNU/Linux.Squashfs используется Live CD дистрибутивами Debian, Finnix, Gentoo, Ubuntu, Fedora, gNewSense, а также во встраиваемых дистрибутивах, таких как прошивки маршрутизаторов OpenWRT и DD-WRT. Кроме того, Squashfs используется совместно с файловыми системами, образующими каскадно-объединённое монтирование, такими как UnionFS и AUFS, чтобы предоставить возможность использовать Live CD дистрибутивы Linux в режиме «чтение-запись». Это даёт преимущества от использования высокоскоростного сжатия Squashfs с возможностью производить изменения дистрибутива во время загрузки с Live CD.
