All;We've been running RadosGW on our nautilus cluster for a while, and we're going to be adding iSCSI capabilities to our cluster, via 2 additional servers. I intend to also run RadosGW on these servers. That begs the question of how to "load balance" these servers. I don't believe that we need true load balancing (i.e. through a dedicated proxy), and I'd rather not add the complexity and single point of failure. The question then is: Does RadosGW play nice with round-robin DNS? The real question here is whether RadosGW maintains internal client state locally between connections. I would expect it's safe, given that it is HTTP, but I'd prefer to verify.
I am also very interested in the answer — we are operating 3 RGW instances
since over a year with DNS load balancing, but never asked this question,
and did not observe any issues. It would of course be nice to see this
confirmed ;-).
However, most of our clients are using systemd-resolved for DNS caching, as
most Linux distributions do nowadays.
This breaks load-balancing of each client (i.e. each client stays with a chosen
address after the initial DNS query for the cache period)[0],
so it might be that if there is an issue, this is hidden by the way most of our
client systems behave.
Cheers,
Oliver
