bismillah ..
seperti di postingan sebelum nya di https://aldykustyandi.com/resize-disk-guest-vm-di-proxmox/ , kali ini yang akan di resize adalah vm dengan OS centos 7 , basis disk nya menggunakan LVM jadi agak berbeda

pertama resize di menu hardware di web console proxmox seperti sebelum nya , kemudian kita ssh ke vm kita lakukan resize physical volume , volume group kemudian logical voulume nya

berikut posisi sebelum di resize lvm nya tapi sudah di resize virtual disk dari web console promxox , terlihat di fdisk -l

pertama kita resize partisi nya dengan parted kemudian resize physical volume nya

[root@#localhost ~]# parted /dev/sda

terlihat dari command vgdisplay VG size nya sudah bertambah , tapi lv Size masih sama

kemudia kita resize logical volume nya

[root@#localhost ~]# lvextend -l +100%FREE /dev/centos/root
  Size of logical volume centos/root changed from 27.79 GiB (7115 extents) to <45.80 GiB (11724 extents).
  Logical volume centos/root successfully resized.

LV Size nya sudah bertambah

terahir kita resize di filesystem nya , centos ini menggunakan xfs maka akan kita resize dengan xfs_growfs
