[SOLVED] Proxmox Cluster down / keep Changing MTU
- Thread starter pille99
- Start date
for thus which are interested what the issue was - the Firewall was enabled. on the Node side. i dont know why (i didnt enable it, never ever). after deactivate, set the MTU to 8972 again, wait 3 Mins, the whole Cluster turned working again.
thx Proxmox Team, that you dont like my "language" and dont want my money. i found it myself (didnt think of it because i never activated it)

I feel you... This is literally my worst nightmare. I wake up at night in cold sweat at the thought that one day the firewalls will rise up and revolt against us, enabling themselves randomly.
And then nobody can help me because I keep saying that nothing has changed.
thx for your pointless input. i have no issue with telling what i have done (even i did something wrong), as most honest i am as better other people could help and give thems input (and visa-verse). i do such jobs quite a long time and i know when to activate the firewall. because my network config isnt complete yet and i do not fully understand the firewall yet (datacenter level, node level and VM level) i do not use it and therefore i didnt activate it. anyway, at least i could smile 1 secound about your first part of your post.
2024 and I am having the same issue, all of a sudden 9000 mtu doesn't work and it has changed itself back to 1514. I am finding that proxmox has a lot of bugs, and is not ready for prime time in my opinion. Glad its is just a hobby of mine, and not something I would have to deal with in a professional setting.
