[Kanjani] Ungaguqula kanjani iDebian Wheezy isuke ku-Ext3 noma i-Ext4 iye kuma-Btrfs

Imvamisa yilawo esiwasebenzisayo I-GNU / Linux sisebenzise ukwahlukanisa kwethu abadumile I-Ext2, i-Ext3 ne-Ext4, kepha njengoba sazi, kunezinye izinhlobo zezinhlelo zamafayela kanye Ama-Btrfs ithola ukuthandwa kancane.

Kodwa yini Ama-Btrfs? Ake sibone incazelo emfushane etholakala ku- Wikipedia:

Ama-Btrfs (Isihlahla se-B I-FS noma evame ukubizwa nge- "Butter FS") yi- uhlelo lwefayela kopisha-ngokubhala kumenyezelwe ngu Oracle Corporation ukuze I-GNU / Linux.

Inhloso yawo ukufaka esikhundleni uhlelo lwamanje lwamafayela ext3, isusa inani elikhulu kakhulu lemikhawulo yayo, ikakhulukazi ngosayizi omkhulu wamafayela; ngaphezu kokwamukelwa kobuchwepheshe obusha obungasekelwa yi-ext3. Kubikwa futhi ukuthi "izogxila ekubekezeleni amaphutha, ekulungiseni nasekusebenzeni kalula ekuphatheni."

Yebo, kule ndatshana ngizokukhombisa ukuthi ungayisebenzisa kanjani UDebian Wheezy con Ama-Btrfs, ngilandela izinyathelo engithole kuzo lesi sixhumanisi. Ngicabanga ukuthi akusho ukuthi uma uthatha isinqumo sokwenza ushintsho, kufanele ukwenze lokho ngokuzibeka wena engcupheni nokuthi anginacala nganoma iyiphi inhlekelele ehlobene nedatha yakho. Asiye lapho 😛

Ukusuka ku-Ext3 / 4 uye kuma-Btrfs

1.- Into yokuqala okufanele siyenze ukugcina yonke idatha yethu noma okungcono okwamanje, yenza lokhu kuhlolwa emshinini obonakalayo.

2.- Silanda i .iso ye Ukuhlolwa kwe-Debian bese "uyishisa" kwi-CD noma uyibeke ku- a Imemori ye-USB con Unetbootin ukuqala kule divayisi.

3.- Noma i-athikili yokuqala ingakucacisi, ngicabanga ukuthi kufanele sifake njengoba kunengqondo, futhi uma uhlelo selulungile sibeka:

fsck -f /dev/sdaX

(ukucabanga / i-dev / sdaX yisistimu yefayela yezimpande)

4.- Sifaka umhleli wethu owuthandayo futhi btrfs-amathuluzi (uma ingatholakali).

5.- Bese sikhipha:

btrfs-convert /dev/sdX

6.- Kamuva:

mount /dev/sdX /mnt

Bese:

mount -o bind /dev /mnt/dev
mount -o bind /sys /mnt/sys
mount -o bind /proc /mnt/proc

7.- Sisebenzisa i-Chroot:

chroot /mnt

8. - Sihlela ifayela / njll / fstab, sibheka umugqa lapho kufakwe khona isistimu yefayela yezimpande (/) bese siyashintsha I-UUID por / dev / sdX, sashintsha ext3 / ext4 por btrfs, sishintsha inketho ibe 'okuzenzakalelayo' futhi siguqula inombolo yokugcina (1) ibe ngu-0.

Isibonelo, kimi kungaba ukuguqula lokhu:

UUID=c2bc3236-b089-4f1e-8303-8fc9fab8848f    /    ext4    errors=remount-ro 0   1

bese uyishiya kanjena:

/dev/sdX    /           btrfs    default     0       0

9.- Bese sikhipha:

ls -la /boot

Ngalokhu esikwenzayo ukukhombisa amafayela angaphakathi / ebhuthini ukwenza isiqiniseko sokuthi sinokufana okufana nalokhu: initrd.img-3.2.0-2-686-pae. Esikudingayo umbhalo oza ngemuva 'initrd.img-' okuzoba yiKernel esizoyisebenzisa kumyalo olandelayo:

mkinitramfs 3.2.0-2-686-pae -o /boot/initrd.img-3.2.0-2-686-pae

10.- Kamuva sibuyekeza i-GRUB:

grub-install /dev/sdX
update-grub

Lapho sesiqedile sisebenzisa umyalo:

exit

Ukuphuma impumu.

11.- Siyahlukanisa:

umount /mnt/proc
umount /mnt/dev
umount /mnt/sys
umount /mnt

12.- Siqala kabusha futhi sithandaza !!! 😀

Uma inhlekelele ingenzeki, singaqinisekisa ukuthi sesivele singene Ama-Btrfs ukwenza amasheke alandelayo:

1.- Kanjani izimpande senza:

update-initramfs -u -t -kall

2. - Siphinde sishintshe kufayela / njll / fstab el / dev / sdX por I-UUID. Ukubuka i- I-UUID kusuka ekuhlukaniseni esikwenzayo:

ls -la /dev/disk/by-uuid/ | grep sdΧ

Okufanele kubuyise into enjengale:

lrwxrwxrwx 1 root root 10 abr 19 08:50 0c3299fc-de7b-496f-8cf8-0d0945111b88 -> ../../sda5
lrwxrwxrwx 1 root root 10 abr 19 08:50 2cce04c7-ae67-413b-9773-afe86a36aa39 -> ../../sda6
lrwxrwxrwx 1 root root 10 abr 19 08:50 c2bc3236-b089-4f1e-8303-8fc9fab8848f -> ../../sda1

Uma konke kuhambe kahle, ungasusa isipele esenziwe inqubo yokuguqula (ext2_londoloziwe) Ngokulandelayo:

btrfs subvolume delete /ext2_saved

Kwenziwe 😀
