Bash script untuk mengkloning Ubuntu Partition to clone partisi yang aktif
The clone-ubuntu.sh
bash script mulus akan dan aman mereplikasi 16.04 LTS menjadi partisi untuk upgrade ke 18,04 LTS:
Poin-poin penting untuk dipertimbangkan:
- Anda harus membuat
ext4
partisi kosong yang cukup besar untuk menampung clone Ubuntu 16.04
- Saat memanggil skrip
clone-ubuntu.sh
, partisi tidak dapat dipasang. Script secara otomatis me-mount dan melepas partisi.
- Perintah
rsync
ini digunakan untuk menyalin file dari /
ke partisi clone. Pertama kali Anda menjalankannya clone-ubuntu.sh
akan memakan waktu beberapa menit. Saat kedua kali Anda menjalankan skrip, hanya perubahan file yang diperbarui dan ini akan memakan waktu kurang dari satu menit.
- Anda dapat menjalankan skrip ini dan reboot beberapa kali. Setiap data baru pada target klon akan dihapus untuk mencerminkan
/
file & direktori saat ini.
- Semua pekerjaan Cron
/etc/cron.d
(reboot) dipindahkan ke sub-direktori baru yang disebut /etc/cron.d/hold
. Setelah booting, klon ingatlah untuk menjalankan sudo crontab -e
agar cron job yang dipilih tidak aktif.
- File yang dikloning
/etc/fstab
diubah dengan UUID yang sesuai untuk partisi yang dihidupkan.
- File yang dikloning
/boot/grub/grub.cfg
diubah dengan UUID yang sesuai untuk booting klon yang berhasil. File yang dikloning quiet splash
diubah nosplash
sehingga Anda mendapatkan scrolling terminal messaging. Ini memberikan kesadaran visual untuk mem-boot versi klon daripada versi "Nyata".
update-grub
dijalankan untuk memperbarui Grub dengan opsi menu baru yang menunjuk ke partisi yang dikloning.
- File yang dikloning
/etc/update-manager/release-upgrades
diubah untuk diubah Prompt=never
menjadi Prompt=lts
. Ketika Anda mem-boot clone dan melakukan do-release-upgrade -d
ini memungkinkan Ubuntu 16.04 ditingkatkan menjadi 18.04.
- Sebelum mengkloning layar konfirmasi ditampilkan (diperlihatkan di bagian berikutnya) dan Anda harus mengetik y / Y untuk melanjutkan.
Layar Konfirmasi
Setelah memilih partisi klon target, pertama-tama diverifikasi ext4
jenis partisi dan belum dipasang. Jika tes ini berlalu, pesan konfirmasi kemudian muncul:

NOTE: If you are recloning, new files in clone will be deleted,
modified files are reset to current source content and,
files deleted from clone are added back from source.
Type Y (or y) to proceed. Any other key to exit:
Dalam contoh ini, klon sebelumnya telah dipilih untuk rekloning. Ruang yang tersedia pada klon adalah titik bisu karena kita sudah tahu ada cukup ruang.
Jika Anda memiliki beberapa instalasi Ubuntu, harap verifikasi Anda telah memilih partisi yang tepat untuk mengkloning Ubuntu yang saat ini di-boot, dipasang sebagai /

Ini adalah kesempatan terakhir Anda untuk membatalkan dengan menekan sembarang tombol kecuali y

Salin dan tempel kode bash di atas ke file baru yang disebut /usr/local/bin/clone-ubuntu.sh
. Kemudian buat file baru dapat dieksekusi menggunakan:
sudo chmod a+x /usr/local/bin/clone-ubuntu.sh
Untuk memanggil skrip gunakan:
sudo clone-ubuntu.sh
Cara memutakhirkan klon 16,04 LTS ke Ubuntu 18,04 LTS
Ini adalah bagian "bonus" yang mungkin menarik minat banyak orang.
Nyalakan ulang mesin Anda. The grub
menu akan berisi pilihan menu menunjuk baru ke partisi kloning. Anda juga dapat memilih versi kernel tertentu dari menu Opsi Lanjutan klon .
Salah satu cara untuk mengubah klon 16.04 LTS menjadi 18.04 LTS adalah menjalankan:
sudo do-release-upgrade
Perhatikan bahwa -d
bendera itu diperlukan sebelum 26 Juli 2018 tetapi tidak lagi diperlukan.
Baca konfirmasi peningkatan versi 18.04 dengan seksama .
Sebelum melanjutkan, pastikan penguncian layar tidak aktif dimatikan. Proses peningkatan dapat macet jika komputer Anda membuka layar kunci karena tidak adanya keyboard.
Ringkasan proses peningkatan 18,04
Bagian ini akan spesifik untuk mesin karena aplikasi yang berbeda dipasang oleh pengguna yang berbeda. Berikut ini ringkasan singkat yang saya buat berdasarkan catatan dan memori:
- konfirmasi untuk melanjutkan: ENTER
- paket akan dihapus: Y
- ganti longind.conf: Y
- File konfigurasi '/etc/sane.d/dll.conf', default N, ambil Y
- '/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf' Ambil default N
- File konfigurasi '/etc/pulse/default.pa' default N, ambil Y
- File konfigurasi '/etc/grub.d/30_os-prober' 'default N, ambil N
- Konfigurasi menu grub layar penuh muncul. Ambil pilihan: pertahankan versi lokal saat ini diinstal
- File konfigurasi '/etc/cron.d/anacron', default N, ambil Y untuk melihat apa
- Pesan kesalahan beberapa kali: /sbin/ldconfig.real: Peringatan: mengabaikan file konfigurasi yang tidak dapat dibuka: /etc/ld.so.conf.d/x86_64-linux-gnu_EGL.conf: Tidak ada file atau direktori tersebut
- Non-standar: File konfigurasi '/etc/vnstat.conf' (perbedaan tampilan 1,13 vs 1,18) ambil Y
- 220 paket akan dihapus. (dapat memakan waktu berjam-jam) masukkan Y
- Untuk menyelesaikan upgrade, diperlukan restart. Ambil Y
Perhatikan langkah 10 kebanyakan orang tidak akan pernah melihat. Saya memiliki instalasi driver nVidia lama pada Ubuntu 16.04 saya, saya tidak pernah bisa menghapus sepenuhnya. Ini termasuk karena Anda mungkin memiliki paket lama yang serupa tidak pernah dihapus sepenuhnya.
Grub mengubah menu boot untuk dikloning di bawah UEFI
Tidak seperti upgrade 18.04 saya menemukan upgrade 18.04.1 mengubah konfigurasi Grub UEFI untuk menggunakan menu grub clone daripada menu grub asli sesuai jawaban ini: Dual boot dan file /boot/grub/grub.cfg - yang mana adalah bekas?
$ sudo cat /boot/efi/EFI/ubuntu/grub.cfg
search.fs_uuid b40b3925-70ef-447f-923e-1b05467c00e7 root
set prefix=($root)'/boot/grub'
configfile $prefix/grub.cfg
$ sudo grub-install
Installing for x86_64-efi platform.
Installation finished. No error reported.
Berjalan sudo update-grub
setelah mem-boot partisi asli tidak cukup untuk mengubah yang grub.cfg
dimuat oleh grub. Anda perlu menggunakan sudo grub-install
untuk memaksa grub untuk menggunakan konfigurasi partisi asli.
Baik partisi asli dan partisi klon dapat digunakan update-grub
untuk memelihara /boot/grub/grub.cfg
file mereka sendiri tetapi hanya satu yang dapat digunakan selama boot.
Tentu saja jika Anda ingin grub menggunakan menu grone Clone jangan lakukan langkah-langkah di atas pada partisi asli.
Edit riwayat
Edit 6 Mei 2018 - Tampilan informasi untuk partisi klon kosong (target) diperbaiki.
Edit 26 Agustus 2018 - Gunakan --inplace
opsi dengan rsync
file yang sangat besar seperti file sampah 2 GB tidak diduplikasi pada klon selama proses penyalinan. Ini dapat menyebabkan kesalahan "kehabisan ruang disk". Mengomentari /etc/cron.d
penimpaan karena pengguna mungkin ingin menyimpan atau menginginkan direktori yang berbeda sekaligus. Perbarui instruksi untuk digunakan do-release-upgrade
tanpa -d
tanda karena Ubuntu 18.04.1 LTS sekarang telah dirilis.
