LXC and QEMU .conf file not exist.

[Mersa]

Hello there, I took a backup of my LXC and KVM virtual machines and restored them on a different server. But now my servers are not visible in the server list and it says there is no conf file. I created a conf file, but there is still an error. How can I solve it? The conf file I created is;

arch: amd64
cores: 1
hostname: 590.www
memory: 4096
net0: name=eth0,bridge=vmbr0,firewall=1,gw=84.54.14.145,hwaddr=9A:80:8E:69:EA:F9,ip=84.54.14.156/27,type=veth

first, i would recommend upgrading to the latest stable version.

please post the output of 'qm list' 'pct list' and the task log from the restore to see why it failed

 

[Mersa]

'qm list' and 'pct list' are empty. After the restore the servers were listed and working. This issue arose after deleting the other server (the old server of the virtual machines) in the cluster. Currently, virtual machines are running, but I can't start the stopped ones and I can't take any action on the running ones.

 

[Mersa]

Isn't there a way to regenerate the config files manually or automatically? I can't start servers that are down. Is there anyone who can help?

@dcsapak

 

[dcsapak]

if the restore worked, the config files must be restored. that's the reason i asked for the restore task log

what exactly did you do in what order?
do you have a cluster? where did you restore? where did you backup?

 

[Mersa]

There were 2 proxmox nodes in the cluster. I took a backup from the virtual machines in node 1 and restored it in node 2. Then I completely deleted the node 1 server and turned it off. After closing I got errors about .conf files.

 

[dcsapak]

Then I completely deleted the node 1 server and turned it off

how did you do this? my guess is that the cluster does not have quorum anymore...

can you post the journal/logs ?

you can try to reestablish quorum on the single node by doing 'pvecm expected 1' (don't do this on normal production clusters, only when you are sure it's the only node left)
