Container configuration change

[estebi]

Dear all,

I found no solution on this forum for my problem. Some problems seem to match but the solutions don't.
Here it is : I have 1 node with 6 containers and 1 KVM.
I want to add RAM and cpu units on 2 of the containers. When using the web manager I get this error :

command 'vzctl --skiplock set 101 --cpus 2 --save' failed: exit code 139 (500)

When I do this in the shell I get this error :

Setting CPUs: 2
Unable to create configuration file /etc/pve/nodes/ns380516/openvz/101.conf.tmp: Permission denied

The directory /etc/pve/nodes is readonly : dr-xr-x--- 2 root www-data 0 13 oct. 19:14 nodes
as the subdirectories and files are.

Here are some commands I did :

root@ns380516:/etc/pve# pvecm status
cman_tool: Cannot open connection to cman, is it running ?

I cannot modify anything because the fuse fs is read-only, though it is mounted rw... I cannot start cmon as I don't have any cluster...
I'm totally stucked. My server is in production and up-to-date. Yesterday it was down during 2 hours because I made updates and tried to reconfigure with my containers off.
I really need to increase CPU and RAM on my containers otherwise they will crash very soon !

Please help me !

you write you have no cluster but you post a cluster.conf file. a system without cluster does no have a cluster config.?

try restarting pve-cluster.

service pve-cluster restart
