Dalam kasus ini penginstalan dengan OS linux ubuntu server 18.04LTS pada dedicated server. Saat itu pemilihan partisi standart dengan format LVM yang dipilih. Hal ini bisa saja terjadi ketika kita install di VM(virtual machine)<\/em> dengan standart partisi.<\/p>\n\n\n\n

Issue:
Ketika pemilihan standart partisi, biasanya kita enggan melihat apa saja yang telah terpartisi pada disk kita dan berapa alokasi yang diberikan pada standart partisi. Ketika OS sudah berjalan dan saat itulah masalah muncul. Saat di cek dengan perintah df -h, ternyata kita hanya diberikan size 4GB pada volume \/ atau root yang mana seharusnya pada partisi itu memerlukan size besar. Pada titik ini penting perlu dicatat bahwa nama volume root kita yaitu \/dev\/mapper\/ubuntu–vg-ubuntu–lv , nama path bisa saja berbeda.<\/p>\n\n\n\n

Langkah-langkah:ssh ke server dan masuk menggunakan root<\/strong><\/em><\/p>\n\n\n\n

Pada output dibawah ini, terdapat ruang disk \/ atau root yang sangat terbatas yaitu hanya 4G. Padahal size sda3 110.8G.<\/p>\n\n\n\n

\"\"
lsblk<\/figcaption><\/figure>\n\n\n\n

Intruksi ini menggunakan perintah parted<\/strong><\/em> kemudian print <\/strong><\/em>untuk menampilkan size setiap partisi. Selanjutnya jalankan perintah resizepart<\/strong><\/em> untuk memperluas partisi serta memaksimalkan seluruh disk dan pilih partisi nomer 3 .<\/p>\n\n\n\n

\n
\"\"<\/figure>\n<\/figure>\n\n\n\n

Sebelumnya saya mencoba menggunakan lvresize \/dev\/sda3<\/em> tetapi tidak berhasil. \u201cPerbedaan lvresize dengan lvextend ialah lvextend hanya bisa memperbesar ukuran volume, sedangkan lvresize bisa menambah atau mengurangi.\u201d Karena belum berhasil maka jalankan perintah kedua yaitu <\/p>\n\n\n\n

lvextend -l +100%FREE \/dev\/mapper\/ubuntu–vg-ubuntu–lv<\/strong><\/em><\/p>\n\n\n\n

\n
\"\"<\/figure>\n<\/figure>\n\n\n\n

Setelah menjalankan lvextend, size belum berubah dan perlu di lakukan resize2fs untuk menambah serta mengubah ukuran. resize2fs \/dev\/mapper\/ubuntu–vg-ubuntu–lv<\/em><\/p>\n\n\n\n

\n
\"\"<\/figure>\n<\/figure>\n\n\n\n
Jika diatas menggunakan ubuntu 18.04, dibawah ini menggunakan Ubuntu 24.04 LTS.<\/h5>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Tujuan:<\/strong> menggunakan seluruh kapasitas dari \/dev\/sda3 (18.2GB) untuk partisi root (\/), yang saat ini masih 10GB (LVM logical volume).<\/p>\n\n\n\n

Kondisi Saat Ini (berdasarkan gambar):<\/strong>
sda3 \u2192 18.2GB \u2192 digunakan untuk LVM<\/p>\n\n\n\n

Di dalam LVM:<\/strong>
Volume Group: ubuntu-vg
Logical Volume: ubuntu-lv \u2192 digunakan sebagai root \/ \u2192 baru 10GB<\/p>\n\n\n\n

Tujuan<\/strong>: Perbesar ukuran root \/ menggunakan sisa space LVM dari sda3

Langkah-langkah (aman & tanpa reboot)<\/strong>
Jalankan sebagai root atau dengan sudo.<\/p>\n\n\n\n

    \n
  • Cek VG (Volume Group) size<\/strong>
    vgdisplay<\/strong>
    Lihat apakah Free PE \/ Size masih banyak. Misal: Free PE \/ Size = 2105 \/ 8.2 GiB \u2192 artinya masih ada ruang yang bisa digunakan.<\/li>\n<\/ul>\n\n\n\n
    \"\"<\/figure>\n\n\n\n
      \n
    • Perbesar Logical Volume<\/strong><\/li>\n<\/ul>\n\n\n\n
      lvextend -l +100%FREE \/dev\/ubuntu-vg\/ubuntu-lv\n\ud83d\udcdd Arti: +100%FREE: pakai semua space kosong yang tersedia di VG<\/code><\/pre>\n\n\n\n
      \"\"<\/figure>\n\n\n\n
        \n
      • Resize filesystem (agar root \/ mengenali kapasitas baru)<\/strong>
        Untuk filesystem EXT4<\/strong> (umum di Ubuntu):<\/li>\n<\/ul>\n\n\n\n
        resize2fs \/dev\/ubuntu-vg\/ubuntu-lv<\/code><\/pre>\n\n\n\n
        \"\"<\/figure>\n\n\n\n
        Kalau pakai XFS (cek pakai df -T dulu):<\/p>\n\n\n\n
        xfs_growfs \/<\/code><\/pre>\n\n\n\n
        \"\"
        Hasil Akhir<\/figcaption><\/figure>\n\n\n\n
        \u26a0\ufe0f Catatan<\/p>\n\n\n\n
          \n
        • Tidak perlu unmount \/ karena ini dilakukan live (online).<\/li>\n\n\n\n
        • Jangan reboot atau matikan sistem saat proses berlangsung.<\/li>\n\n\n\n
        • Kalau resize2fs tidak tersedia, install:
          sudo apt install e2fsprogs<\/em><\/li>\n<\/ul>\n\n\n\n
