Ubuntu Hanya Mendeteksi 100Gb Hard Disk

Entah mengapa, setiap install OS Ubuntu tetapi hanya mendeteksi 100Gb dari hard disk, padahal sudah dipasang 500Gb atau berapa pun diatas 100Gb. Jika Anda mengalaminya, mungkin bisa ikuti langkah berikut agar Ubuntu menggunakan semua kapasitas hard disk.

df -h
Filesystem                         Size  Used Avail Use% Mounted on
tmpfs                              6.3G  1.3M  6.3G   1% /run
/dev/mapper/ubuntu--vg-ubuntu--lv   98G   12G   82G  13% /
tmpfs                               32G     0   32G   0% /dev/shm
tmpfs                              5.0M     0  5.0M   0% /run/lock
/dev/sda2                          2.0G  130M  1.7G   8% /boot
tmpfs                              6.3G  4.0K  6.3G   1% /run/user/1000

Dan kalau check menggunakan perintah lsblk -p terlihat jelas kalau hard disknya sebesar 500Gb.

lsblk -p
NAME                                  MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
/dev/loop0                              7:0    0   62M  1 loop 
/dev/loop1                              7:1    0 79.9M  1 loop /snap/lxd/22923
/dev/loop2                              7:2    0   47M  1 loop /snap/snapd/16292
/dev/loop3                              7:3    0 63.9M  1 loop /snap/core20/2182
/dev/loop4                              7:4    0 63.9M  1 loop /snap/core20/2264
/dev/sda                                8:0    0  500G  0 disk 
├─/dev/sda1                             8:1    0    1M  0 part 
├─/dev/sda2                             8:2    0    2G  0 part /boot
└─/dev/sda3                             8:3    0  498G  0 part 
  └─/dev/mapper/ubuntu--vg-ubuntu--lv 253:0    0  100G  0 lvm  /
/dev/sr0                               11:0    1 1024M  0 rom

Dan untuk membenarkan semuanya, menggunakan 2 perintah berikut, yaitu:

sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
  Size of logical volume ubuntu-vg/ubuntu-lv changed from 100.00 GiB (25600 extents) to <498.00 GiB (127487 extents).
  Logical volume ubuntu-vg/ubuntu-lv successfully resized.

sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
resize2fs 1.46.5 (30-Dec-2021)
Filesystem at /dev/mapper/ubuntu--vg-ubuntu--lv is mounted on /; on-line resizing required
old_desc_blocks = 13, new_desc_blocks = 63
The filesystem on /dev/mapper/ubuntu--vg-ubuntu--lv is now 130546688 (4k) blocks long.

Setelah menjalankan 2 perintah diatas, maka partisi akan menggunakan semua hard disk yang kita punya.

df -h
Filesystem                         Size  Used Avail Use% Mounted on
tmpfs                              6.3G  1.3M  6.3G   1% /run
