[SOLVED] Is is possible to specify the NIC used for storage replication?

[jsalas424]

I have a 3 node cluster running PVE 7.1-10. I am successfully replicating a pfsense VM between two nodes in my cluster, but it's going over my LAN NIC instead of my dedicated cluster network. Is there a way I can specify the NIC for replication?

Even better, can I specify a primary and fallback network?

Hi,
I think you can use the migration setting in your /etc/pve/datacenter.cfg (see man 5 datacenter.cfg for details). The network given there should also be used for replication.

I'm struggling with the syntax would you mind taking a look?

This is what the man says:

FILE FORMAT
       The file uses a simple colon separated key/value format. Each line has the following format:

           OPTION: value

       Blank lines in the file are ignored, and lines starting with a # character are treated as comments and are
       also ignored.

..................................................................................................

migration: [type=]<secure|insecure> [,network=<CIDR>]
           For cluster wide migration settings.

           network=<CIDR>
               CIDR of the (sub) network that is used for migration.

           type=<insecure | secure> (default = secure)
               Migration traffic is encrypted using an SSH tunnel by default. On secure, completely private
               networks this can be disabled to increase performance.

What I have:

# cat /etc/pve/datacenter.cfg
keyboard: en-us
migration: type=insecure ,network=10.0.0.0/24

Error code:

()
parse error in '/etc/pve/datacenter.cfg' - 'migration': invalid format - format error
migration.type: value 'insecure ' does not have a value in the enumeration 'secure, insecure'

migration: insecure,network=172.17.93.0/24

I'd remove the "type=" and maybe the space around the ,

Thank you! This worked swimmingly.

Just a short question: does the migration setting only affects manual migration tasks, is it also used for cluster replication tasks done by the cluster node itself?

yes, it also affects replication. That's what this thread is all about
