[SOLVED] changing hostname messed

[pats]

Hi,

I changed hostname in Debian and also followed what i read in this forum "You also need to fix /etc/hosts (and reboot), and then rename the directory where the VM configs are stored (/etc/pve/nodes/[NODENAME]) "
# mv /etc/pve/nodes/server /etc/pve/nodes/prox1

After that i tried to login in Proxmox but got error - login failed, though username/password was correct.

When i do root@prox1:~# pvecm updatecerts get error "unable to get IP for node 'prox1' - node offline?"

i was getting this error also:

root@prox1:~# dpkg-reconfigure pve-manager
Restarting PVE Daemon: pvedaemon.
Restarting PVE Status Daemon: pvestatd.
Syntax error on line 13 of /etc/apache2/sites-enabled/pve-redirect.conf:
SSLCertificateFile: file '/etc/pve/local/pve-ssl.pem' does not exist or is empty
Action 'configtest' failed.
The Apache error log may have more information.
failed!
invoke-rc.d: initscript apache2, action "restart" failed.

Then i saw pve-ssl.pem in /etc/pve/nodes/ so i coped them

root@prox1:~# cp /etc/pve/nodes/pve*.* /etc/pve/local/
cp: target `/etc/pve/local/' is not a directory

root@prox1:~# ls -l /etc/pve/local/
ls: cannot access /etc/pve/local/: No such file or directory
drwxr-x--- 6 root www-data 4096 Jul 21 16:06 nodes
root@prox1:~# mkdir /etc/pve/local
root@prox1:~# cp /etc/pve/nodes/pve*.* /etc/pve/local/
root@prox1:~# dpkg-reconfigure pve-manager
Restarting PVE Daemon: pvedaemon.
Restarting PVE Status Daemon: pvestatd.
Restarting web server: apache2.

help pls...

I guess you need reboot the host (or restart all services).

 

[pats]

from SSH, i rebooted the server 2-3 times... no help..
- i can't login to Proxmox 'root@pam'
- still getting error, # pvecm updatecerts -> "unable to get IP for node 'prox1' - node offline?"
- also i'm not sure if the file i copied, SSLCertificateFile pve-ssl.pem was correct or not. Though it removed the error message as mentioned above.

- still getting error, # pvecm updatecerts -> "unable to get IP for node 'prox1' - node offline?"

Please check /etc/hostname and /etc/hosts

 

[pats]

root@prox1:~# cat /etc/hostname
prox1

root@prox1:~# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
74.91.18.1 prox1.xyzdns.com prox1 pvelocalhost

# The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
root@prox1:~#

these both look ok to me, however i find files/folders missing in '/etc/pve' maybe due to 'pvecm updatecerts' & 'dpkg-reconfigure pve-manager' not able to complete properly
How to correct/rebuild? (This standalone node had only 1 Container CT100)

root@prox1:~# ls -l /etc/pve

[pats]

anyone?

 

[dietmar]

Seems there a no VMs on that node? If so, its maybe faster to do a re-install.

 

[pats]

as i mentioned, i have one live OpenVZ container CT100 in the node. And i also have Dump of that CT100 on 2nd Hard Drive.

Can i re-install and re-create CT100 (Restore from the Dump) without any issue?

[dietmar]

vzrestore should work. But what is the output of

# /etc/pve/pve-cluster start

Does that recreate the missing files? If not, any hints in /var/log/syslog.

 

[pats]

Cluster? this is standalone Proxmox bare-metal with 1 node..

root@prox1:~# /etc/pve/pve-cluster start
-bash: /etc/pve/pve-cluster: No such file or directory


root@prox1:~# tail -f -n 50 /var/log/syslog

and then i searched for this new error "WARNING: ipcc_send_rec failed: Connection refused" and found a post in this forum, so i tried..

problem is similar to http://forum.proxmox.com/archive/index.php/t-9889.html where 2ns last command says The directory '/etc/pve/' needs to be empty.

root@prox1:~# ls -l /etc/pve

drwxr-x--- 4 root www-data 4096 Jul 22 13:42 nodes
root@prox1:~#

Should i 'rm -rf local' & 'nodes' to make it empty?

thanks

 

[dietmar]

Should i 'rm -rf local' & 'nodes' to make it empty?

Yes, but backup any files.

# mv /etc/pve /etc/pve.backup
# mkdir /etc/pve

ok now i can login to Proxmox gui but Datacenter view is below

Datacenter
|--prox1 (green light - up)
. . |--local(prox1) - hard disk
. . |--BKD1(prox1) - backup drive
|--server (red light - down)
. . |--100 (VZ container - down)

The container is under previous hostname 'server' while the storage under the new hostname 'prox1'.
How to move the container CT 100 under 'prox1' ?

Can i move -
# mv /etc/pve/nodes/server/openvz/* /etc/pve/nodes/prox1/openvz/
or
# mv /etc/pve/nodes/server/* /etc/pve/nodes/prox1/ (so that it moves the keys also pve-ssl.key , pve-ssl.pem)

i'm also thinking that some reference of old hostname is still there thats why after making /etc/pve empty and 'dpkg-reconfigure pve-manager', its putting CT100 under old hostname.
where to find that reference and correct it...

thanks

Yes, simply move files to the correct node.
