Modify files in /etc/pve

[grobs]

Hi,

I would like to change some settings in some /etc/pve/* files on my physical Proxmox hosts but I'm not able to create or modify files in this directory :

# touch /etc/pve/test.file
touch: impossible de faire un touch « /etc/pve/test.file »: Périphérique ou ressource occupé

# mount | grep /etc/pve
/dev/fuse on /etc/pve type fuse (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other)

# grep pve /etc/fstab
/dev/pve/data   /var/lib/vz   ext3   defaults   0   2

Is it normal? How can I modify those files (/etc/pve/storage.cfg, /etc/pve/user.cfg, /etc/pve/priv/known_hosts)?

This is not normal. Is your cluster quorate?

But you run a really outdated version, so I suggest to update your system.

Thank you dietmar, your replies are always relevent and very quick!

As I am a beginner with proxmox (managing a cluster created by another person which is no longer with me), I don't know anythink about the Proxmox cluster quorum so I'll read some docs about it.

In short, more than half of your cluster nodes needs to be online. Else /etc/pve/ will switch to read-only mode.

All my nodes are up and running but maybe that a configuration problem is avoiding the cluster to be "ok".
I read here that it's way easier when nodes are in the same subnet. My nodes are OVH dedicated servers and have public IPs on different subnets. Maybe that I have to deal with OVH VLAN management interface to get a virtual subnet for all my cluster nodes?

Sorry, I never tested such setup. We only support clusters on a single/local network.
