Hello
I have a server which had been running Proxmox 2.0 since December. according to aptitude logs it originally had proxmox-ve-2.6.32 2.0-53 . the node name is fbc241 .

Today I backed up and removed the vm's and added fbc241 to the cluster. here is pvecm status and nodes:

fbc241 s012 /var/log # pvecm nodes
Node  Sts   Inc   Joined               Name
   1   M    196   2012-04-16 06:38:08  s009

   4   M    188   2012-04-16 06:37:42  fbc241

fbc241 s012 /var/log # pvecm status
Version: 6.2.0
Config Version: 19
Cluster Name: fbcluster
Cluster Id: 52020
Cluster Member: Yes

Node name: fbc241
Node ID: 4
Multicast addresses: 239.192.203.0 
Node addresses: 10.100.100.241

The problem is on the pve screen, when I try to click on fbc241 this error displays:
"Connect failed: connect: Connection refused; Connection refused (500) "

Other issues:
from other nodes ' ssh fbc241 ' requires a password, even when trying 'ssh-copy-id ' .

/root/.ssh/ :has
authorized_keys -> /etc/pve/priv/authorized_keys

but if I copy the original authorized_keys back ssh login does not need a password.

In the past when I ran into this problem a reinstall is the only solution I could find.

But it would be good to try to fix this issue incase anyone else runs in to the problem.


Any suggestions?


ps: thank you for the great Proxmox PVE system.

after checking other threads :

ls -l /etc/pve/local/pve-ssl.pem
ls: cannot access /etc/pve/local/pve-ssl.pem: No such file or directory

pvecm updatecerts
fbc241 s012 ~ # ls -l /etc/pve/local/pve-ssl.pem                                                                                      
-rw-r----- 1 root www-data 1363 Apr 16 08:36 /etc/pve/local/pve-ssl.pem

still get the error. try rebooting node fbc241

that fixed pve access. the connection error is gone.

but ssh logins are not ok:

root@fbc1 /home/rob/Downloads # ssh-copy-id fbc241
root@fbc241's password: 
Now try logging into the machine, with "ssh 'fbc241'", and check in:

  .ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.
# 
# then try to log in, but password is still needed:
ssh fbc241
root@fbc241's password:

the ssh issue fixed it self. I do not know how, my guess is a cluster cronscript did something.

the ssh issue had something to do with the old server running one of our cronscripts which was ok for non cluster setup.
