can't access with hostname after expanding drive

Hi everyone,

a while ago I switched from a 500GB SSD to a 2TB SSD and expanded the drive and both local and local_lvm.
In this process I must have broken something because since then I can't reach Proxmox with it's hostname. The only way is through IP (which didn't change) or with the hostname "ubuntu".

I checked every hostname file I know but there is no entry for ubuntu.

Does anyone have an idea where the problem lies?


PS: I wasn't sure if this was configuration or networking. I assumes that networking is inside the proxmox installation.
The problem lies in name resolution on your network. That is usually DNS but also might be mDNS or Bonjour or something but those are less common.

How is Proxmox getting its non-changing IP? Is it static in /etc/network/interfaces, or are you having an assignment in your DHCP server? In the former case, check your DNS and see what name you've assigned. In the latter you need to find out what name your Proxmox is sending in the DHCP request. What's in /etc/hostname and what does "hostname -f" return?
