Can't create new VM: no quroum

[sam1994]

HiMy VMs do not autostart and I cannot create a new VM (CT based on Proxmox 2.0). I once tried to set up a node but did not do so in the end. Here is my cluster.conf:

root@vmhost:~# cat /etc/pve/cluster.conf

I try and run pvecm nodes to see what 'nodes' Proxmox thinks I have, and remove them. I get

cman_tool: Cannot open connection to cman, is it running ?

so I try service cman start. Then I get:

root@vmhost:~# service cman startStarting cluster:    Checking if cluster has been disabled at boot... [  OK  ]   Checking Network Manager... [  OK  ]   Global setup... [  OK  ]   Loading kernel modules... [  OK  ]   Mounting configfs... [  OK  ]   Starting cman... Cannot find node name in cluster.confUnable to get the configurationCannot find node name in cluster.confcman_tool: corosync daemon didn't start Check cluster logs for details[FAILED]

My cluster.conf doesn't actually define any nodes, so I'm not sure how to proceed here. I just want to get Proxmox to allow me to create more CTs in the web interface, I do not want it to be part of a cluster.Thanks in advance

Hi,
/etc/pve/cluster.conf don't excist on an standalone pvehost!
Can you delete the empty file?

And that cman don't run is ok.

I can't delete cluster.conf, even as root!root@vmhost:~# rm /etc/pve/cluster.confrm: cannot remove `/etc/pve/cluster.conf': Permission deniedIt shouldn't exist, but I think I once tried to set it up as a cluster. Thanks

Hi,
perhaps this help: http://forum.proxmox.com/threads/11398-Full-remove-Cluster-feature?p=62872#post62872 (only till creating an new cluster).

Hi,
you have rebootet your node? Does /etc/pve is writable?

Udo

 

[sam1994]

Rebooted, now gettingAug 17 12:41:49 vmhost pmxcfs[2468]: [status] crit: cpg_send_message failed: 9in syslog constantly.pve-cluster service is already running (have checked this)this is bad. We are in a production environment!

 

[udo]

Hi,
and you cluster-files are deletet?
And again: /etc/pve is mounted and writable?

Udo

This is my df outputudev 10M 0 10M 0% /devtmpfs 798M 332K 797M 1% /run/dev/mapper/pve-root 95G 1.2G 89G 2% /tmpfs 5.0M 0 5.0M 0% /run/locktmpfs 1.6G 3.1M 1.6G 1% /run/shm/dev/mapper/pve-data 341G 65G 277G 19% /var/lib/vz/dev/sda1 495M 37M 433M 8% /boot/dev/fuse 30M 12K 30M 1% /etc/pve

Hi,
say nothing about writable or not.

Better would be "mount | grep pve".

Can you create an dummy-file like "touch /etc/pve/dummy"?

Udo

 

[sam1994]

No, I get permission denied if I try to touch it

 

[sam1994]

But umount /etc/pve says it is not mounted

 

[udo]

Hi,
is cman now running or not?
because if you are an one-node-cluster you can get quorum with "pvecm expected 1".

But this sounds that you don't do all steps of the linked post (backup /etc/pve; umount /etc/pve, remove cluster files; reboot).

Udo

 

[sam1994]

Had to restore the backup of /etc/pve to get containers booting againweb interface now doesn't show containers at all

Hi,
I guess because your /etc/pve isn't mounted?!

sorry - no skype (it's evil ;-) )

I replied again on your profile

Udo has fixed the issue. Many thanks to him.Following his original link would have worked, however it should be noted when you mv /etc/pve to a backup directory, you should mkdir a fresh /etc/pve as restarting the service won't do this for you!
