Overview

Handler for the ‘pvectl set volume` command.

Does NOT use SetResourceCommand template — has custom flow due to different argument structure (resource_type + id + disk + key=value).

Examples:

Resize volume

pvectl set volume vm 100 scsi0 size=+10G

Set cache mode

pvectl set volume vm 100 scsi0 cache=writeback

Mixed operations

pvectl set volume vm 100 scsi0 size=+10G cache=writeback --yes
