PVE host not accessible after power shutdown; VMs working

[Homer-S]

Hello,
we had an issue with our power supply. Proxmox server was killed by no power supply. After restarting the engine, I was able to SSH in and it looked quite ok.
After running for a few hours I am not able to access Web GUI neither SSH. Fun fact: all VMs / LXCs are running like expected.

Any ideas how to solve it or at least, where to search for the issue?

Thanks

Edit 1: I can not ping the internal ip; Router is showing ip with known IP address.
Edit 2: With a Display/keynoard I am able to log in directly at the server. The host can ping his ip address and others.

hi,

Any ideas how to solve it or at least, where to search for the issue?

check your journalctl, hopefully the filesystem wasn't corrupted by the power loss.

for the network issue, if your PVE host can reach the local network and internet but is not accessible, then take a look at your firewall settings and if the SSH and pveproxy service are still running.

When I plugged a display into the server, this showed up first




192.168.100.22 is accessible by others

I checked status of sshd/ssh/pveproxy services. all are active
afaik there I have no firewall on this server only on router

checking dmesg I have a lot of this one:

error in your dmesg about ACPI shouldn't case issues, though i see that you have docker installed on the PVE host. this is not recommended because it can mess with the networking stack of the host, i'd suggest removing docker from the host and check if the network issue still occurs.

 

[Homer-S]

docker is installed in some LXC but not directly on the host. ..?!

 

[oguz]

docker is installed in some LXC but not directly on the host. ..?!

are you sure?

if you run ip a on the host what do you get?

are you sure?

if you run ip a on the host what do you get?

I receive this:
but if I am doing
docker -v
I am receiving an error???
