Pada 240 GB SSD saya, saya memiliki dua partisi pertama, satu berisi Logical Volume dengan Linux Mint dan yang lainnya berisi partisi NTFS untuk dibagikan dengan Windows. Sekarang saya menghapus partisi NTFS dan ingin memperluas grup volume logis saya untuk menggunakan ruang disk yang dirilis.
Bagaimana cara memperpanjang grup volume , volume logis saya yang berisi / home dan filesystem (ext4) di / home? Apakah ini mungkin dilakukan secara online?
PS: Ya, saya tahu harus mencadangkan data saya :)
/dev/sdb/ (240GB)
linuxvg (160GB) should use 100% of the disk space
swap
root
home (ext4, 128GB) should be extended to use the remaining space

, daripada menghapus partisi sepenuhnya. Jika Anda menumbuhkan partisi PV yang ada sebagai gantinya Anda mungkin harus reboot, karena Linux menolak untuk membaca kembali tabel partisi saat disk sedang digunakan. Mengatasi masalah online ini terasa canggung. - Tolong tunjukkan tabel partisi Anda saat ini.
