hello, I apologize for bothering once again. I have stucked here for some hours.
I was not able to access the Node-RED flow, entered to the Proxmox virtual environment and identified that K3OS VM had a warning "(io-error).
I found in the documentation this troubleshooting guide
https://learn.umh.app/guides/open-source/proxmox/tutorial/disable-swap-proxmox/, and executed it in the console. Rebooted the system and still the warning.
May I ask your support, how to delete and release capacity in local lvm?
