Tot ma intreaba X si Y, cum sa maresti spatiul pentru un disk dintr-un KVM administrat de SolusVM. Asa ca m-am gandit sa pun aici public, sa nu mai stau sa rescriu mereu:)

1. se mareste spatiul alocat pentru masina in cauza in SolusVM (in interfata grafica)

2. se rescrie configul, tot din aceeasi interfata

3. se cauta pe host-ul unde ruleaza masina virtuala disk-ul masinii virtuale, il puteti gasi in /etc/libvirt/qemu sau in Build log-ul din interfata SolusVM cel mai rapid.

[root@host qemu]# lvdisplay /dev/centos/kvm67200_img
  — Logical volume —
  LV Path                /dev/centos/kvm67200_img
  LV Name                kvm67200_img
  VG Name                centos
  LV UUID                BfVeHe-0gao-Jge6-yLBd-nW1D-VXpb-6VqIhh

4. Daca volumul este activ, il dezactivam temporar

[root@host qemu]# lvextend /dev/centos/kvm67200_img -L+45G
  Snapshot origin volumes can be resized only while inactive: try lvchange -an.

[root@host qemu]# lvchange -an /dev/centos/kvm67200_img

5. Marim spatiul diskului

[root@host qemu]# lvextend /dev/centos/kvm67200_img -L+45G
  Size of logical volume centos/kvm67200_img changed from 80.00 GiB (2560 extents) to 125.00 GiB (4000 extents).
  Logical volume centos/kvm67200_img successfully resized.

6. Reactivam volumul

[root@host qemu]# lvchange -ay /dev/centos/kvm67200_img

7. Repornim masina virtuala cu gparted si fixam/realocam noul spatiu nefolosit.

Atentie: Desigur este bine sa faceti un backup inainte sa faceti resize!
