[SOLVED] VM disappeared from webui after removing server from cluster

[pier]

Hi,

I am in a bit of a situation now, I tried to remove my only server from a one server only cluster, and after achieveing the process all VM's have disapeared from the web UI, I understand I did not do the right thing, so for now i am just looking for a way to restore running vm/lxc to the webUI in order to be able to manage them.

Is there any way of recovering disapeared vm/lxc from web ui as they are still running ?

thank you

[edit] : I did not follow the official guide to get rid of the existing cluster, I know it is bad, and I have no excuses for this, although the situation was kind of complicated, it is now getting worse, of course....

How you removed the node from the cluster?

Still you can do the PVE commands e.g:

qm list
pct list

Do you see the/etc/pve path?

check the config of the VMs

/etc/pve/nodes/{nodename}/qemu-server/

and for LXC's

/etc/pve/nodes/{NodeName}/lxc/105.conf

Hi Moayad,

Thanks for the wuick reply, I removed the cluster by following this : https://blog.zwindler.fr/2017/09/19/tutoriel-demonter-proprement-cluster-proxmox-ve/
My cluster was initially composed of 2 server, I removed the first one, then the last one to get 2 standalone servers, bad idea....

Unfortunately all conf from /etc/pve/{NodeName}/{lxc|qemu-server}/ are gone, otherwise that'd be quite easy ...

My VM are still running, I can reach'em, but they are just not visible from the webui.

/etc/pve is mounted :

-rw-r----- 1 root www-data  119 Aug 11 15:02 vzdump.cron

qm list and pct list does not print anything, as the config files are gone.

Any way to retrieve conf ig file from the running lxc/qemu ? Or any other way to get the vm/container back in the web ui ?


[EDIT]
I managed to recover lost vm using a (dunno from where it comes but thanks for that !) list and config files from the first node I removed from the cluster... This was a life saver.

Lesson learned (I'm 42 yo, I should really learn from my errors ...)

Thanks again for your support
