Resize Storage VM (Ubuntu 20.04) on Proxmox

Resize terlebih dahulu Storage pada VM di Proxmox
contoh dari 100 GB menjadi 150GB
lalu chek list partisi yang terdapat pada server dengan menjalankan fdisk -l

embyhost@embyhost:~$ sudo fdisk -l
...
GPT PMBR size mismatch (1572863999 != 2621439999) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write.

atau juga dapat menggunakan perintah gparted

embyhost@embyhost:~$ sudo parted /dev/sda

Warning: Not all of the space available to /dev/sda appears to be used, you can fix the GPT to use all of the space (an extra 1048576000
blocks) or continue with the current setting?

jalankan perintah resizepart, jika partisinya adalan sda2 maka tuliskan resizepart 2 100% ( angka 2 menyesuaikan nama partisi )
(parted) resizepart 2 100%                                              
Warning: Partition /dev/sda2 is being used. Are you sure you want to continue?
parted: invalid token: 100%

(parted) quit                                                             
Information: You may need to update /etc/fstab.

langkah selanjutnya adalah menjalankan perintah resize2fs pada partisi yang akan di resize

embyhost@embyhost:~$ sudo resize2fs /dev/sda2
resize2fs 1.45.3 (14-Jul-2019)
Filesystem at /dev/sda2 is mounted on /; on-line resizing required
old_desc_blocks = 94, new_desc_blocks = 157
The filesystem on /dev/sda2 is now 327679483 (4k) blocks long.

reboot system dan lakukan pengechekan pada server dengan menggunakan perintah df -h

Selesai
