I just want you let to know how to increase the disksize of a Nethserver running under Proxmox.
For example we have a Nethserver with the Proxmox VM-ID of 106 and we want to grow the size from 500GB to 1000GB…
On the Proxmox CLI:
qm resize 106 virtio0 +500G
On the Nethserver CLI:
resizepart 2 100%
lvextend --resizefs -l +100%FREE /dev/mapper/VolGroup-lv_root
