[SOLVED] Can´t add third node to cluster

[Thomas15]

Hello everyone,

I have a problem when trying to add a 3rd node to an existing 2 node cluster. Every node has three network interfaces, one bonding with 2x1GBit/s for vmbr0 at 192.168.141.0/24 and two fiber channels on 10.50.0.0/24 and 10.50.2.0/24 with 10GBit/s each.

When using pvecm add 10.50.2.112 on the new third host to join the cluster I get this error:



Login succeeded.
check cluster join API version
No cluster network links passed explicitly, fallback to local node IP '192.168.141.121'
Request addition of this node
An error occured on the cluster node: error during cfs-locked 'file-corosync_conf' operation: no links given but multiple links found on other nodes, fallback only supported on single-link clusters
Cluster join aborted!-


pvecm status on the current two node cluster

And just after I posted here my brain started to work properly and I could find that I just need to give the additional links I want like this to the command:

--link0 10.50.0.121 --link1 10.50.2.121
