How to extend disk zabbix appliance 5.0 LTS using OS almalinux

[dngady]

Hi guys,

I want to extend the root disk in Zabbix appliance 5.0 LTS using the KVM image.

Where after downloading the image appliance, the disk just stores 10GB. So I was resized in KVM

# qemu-img info /var/lib/libvirt/images/zabbix_appliance-5.0.24.qcow2
image: /var/lib/libvirt/images/zabbix_appliance-5.0.24.qcow2
file format: qcow2
virtual size: 10G (10737418240 bytes)
disk size: 1.1G
cluster_size: 65536
Format specific information:
compat: 1.1
lazy refcounts: false

# qemu-img resize /var/lib/libvirt/images/zabbix_appliance-5.0.24.qcow2 +100G
Image resized.

# qemu-img info /var/lib/libvirt/images/zabbix_appliance-5.0.24.qcow2
image: /var/lib/libvirt/images/zabbix_appliance-5.0.24.qcow2
file format: qcow2
virtual size: 110G (118111600640 bytes)
disk size: 3.1G
cluster_size: 65536
Format specific information:
compat: 1.1
lazy refcounts: false

And then I want to resize the root disk also inside OS, but it cannot be grown.

[root@appliance ~]# fdisk -l
