Local cache of /etc/pve ?

[Florent]

Hi all,

I would like to know if, when a node (which is part of a cluster) starts, it has a local cache copy of /etc/pve before joining cluster ?

In fact, I would like to use /etc/pve to store configuration files, but I need it to configure network (so it has to be done before joining cluster).

Is it possible ?

If it's not, I will make it with rsync or something else.

Thank you

Hello Florent,

From my experience:

Information about a VM or CT is stored in the node where it is located (/etc/pve/qemu-server/*.conf or /etc/pve/openvz/*.conf)
and can be administered locally.

But if a node is not connected to the other nodes of the cluster these configuration files can be set to read-only and no
configuration change is possible in this case.

Can be resolved by

See related wiki section 4.2 "Two nodes cluster and quorum issues" from https://pve.proxmox.com/wiki/Proxmox_VE_2.0_Cluster

Kind regards

Mr. Holmes

Thank you Mr. Holmes.
Read-only is enough for my needs, I will see that...

Yes, there is a local (read-only) copy. But that copy can be out of date because the file could be modified on another node.
