From standalone node to cluster

[yaboc]

Hi

I have a standalone node connected to FreeNAS via ISCSI running a couple KVMs.

I'd like to create a cluster and add another node to the mix. Can the KVMs be up and running while performing the cluter setup?

Thanks

Yes, I don't see why not, providing the new node does not have any virtual machines installed - add it to the master node and it will appear in the tree structure automatically.

so i should just proceed with cluster setup? https://pve.proxmox.com/wiki/Proxmox_VE_2.0_Cluster
do i need to specify anything as far as my ISCSI connection or will the new code get it from the main node ?

Thanks in advance

yes the node just becomes the first node in the cluster. then you can join others (is a multimaster cluster).
all shareable resources are shared (there is proxmox cluster filesystem that replicates /etc/pve on every cluster node, and that has conf files, dbs, etc.)

this means that if you have a "local" storage, that will be on other nodes too, but it will be "local", meaning a local folder, of course to each node.
instead, a nfs or iscsi share or else will be (if configured properly, see wiki) really shared betwee all cluster nodes.

Yes - good advice!

thanks guys. i successfully created cluster with two nodes connected to iSCSI storage.
