We are using a shared storage array (configured as LVM storage within Proxmox) as disk storage for our KVM guests. To avoid running into problems in the future I have been experimenting with increasing the amount of disk space available to a guest, without success.
My initial thought was to run an lvextend on the corresponding virtual disk and then use a guest-specific process to make use of the extra capacity - adding a partition or extending a volume within the guest. However, after performing the lvextend Proxmox does not seem to register the change in size and the guests do not see any available capacity even after they are restarted.
Am I headed down the wrong path? What is the recommended way to add capacity to a guest in this scenario?
