[SOLVED] high availibility IP address for cluster

[RobFantini]

Hello

I am in the process of setting up ceph-fs to replace our nfs system.

In the old days I'd use heartbeat to make sure an IP address belonged to one cluster member at all times.

As we have not set up something like this in 10 years,


So we are looking for suggestions on some modern ways of sharing one IP address within a pve cluster.

best regards
Rob F

HI,

One possibility is to use ucarp. You have package in any linux distrib. And it is work like a charm/rock-solid.

Do you want to access "only" the PVE GUI with one IP address or some other service inside of your cluster?

If the first is true, we have a HA VM with load balancer traefik that connects you to any PVE node available and sticks your session to it so that you will notice a connection drop only in case of a failover (but this is true for any HA solution based on IP) and you'll only know "where" you are based on the title of your browser window/tab. You can define a simple load balancing, round-robin or whatever you want to spread connections. Maybe this fits your needs.

Maybe you can detail your case with the ssh/rsync and the relation with a cluster IP.

ucarp should solve this. I probably will not get a chance to implement ucarp for a few weeks. I'll let you know if any questions. thank you.
