Deleted /etc/* by accident. Need help.

[Rez]

Hi, I made a mistake, deleted /etc/* by accident, and am in need of some help.


We have three nodes in a cluster, all nodes running Proxmox 3.4-9. On node 3, I accidentally deleted all the files in /etc/*.
I tried to restore the contents of /etc/* from backup and ran apt-get update and apt-get upgrade and then restarted the physical server, but some things do not work correctly.


For example, when I try to log into node 1 or node 2 from the web browser, it says "Login Failed. Please try again"
All three nodes have the same root username and password. When I log into node 3, it works and I can login, but I do not see node 1 or node 2 listed in the tree on the left, I only see node 3.


Also, when I try to ssh into node 1, I get an error such as:
Unable to open /etc/pve/openvz/406239.conf: No such file or directory
Unable to open /etc/pve/openvz/406242.conf: No such file or directory
Unable to open /etc/pve/openvz/406243.conf: No such file or directory
Unable to open /etc/pve/openvz/406244.conf: No such file or directory
When I ssh into node 2 or node 3 I do not see the above messages.


Is there a way to fix it so that I can log into node 1 or node 2 from the web browser?
Also, how can I make node 3 show nodes 1 and 2 in the tree in the web browser?


Much thankful for you help.

Hum, difficult.
I would try to remove the nodes from the cluster ( there is documentation in the wiki) check if it solves your login problem, and then re-add the nodes to the cluster.

Hi,
do you remove the content recursive? (rm -r /etc/*)??
has /etc/pve/ on the other nodes content?

find /etc/pve -ls

If there is content, I think it's an good idea to make an additional backup on a running node (like "tar cvf /root/etc_pve.tar /etc/pve").

Thanks for the response.

I removed it recursive, rm -r /etc/*
/etc/pve does not have any contents on any of the nodes 1, 2, and 3.
Did removing the contents in /etc/pve/ on node 3 replicate to nodes 1 and 2? Should there be contents there in /etc/pve/? How can I bring it back?

I'll try the suggestion of removing the nodes from the cluster.

I'll try the suggestion of removing the nodes from the cluster.

Hi,
I suggest to do nothing like this with an empty /etc/pve on all nodes!!!
