[ceph-users] HA service for RGW and dnsmasq

Hello everyone, We operate 2 clusters as S3 external storage for owncloud. Both were installed with ceph-deploy (Nautilus), then converted to cephadm and updated till Reef. Each cluster has one RGW host, managing a dnsmasq pack for DNS delegation. We feel know we should create a HA endpoint for RGW as explained in Reef doc. We have a few questions that we didn't find answers in the doc before proceeding :   - is dnsmasq still needed on the existing ans new RGW hosts ?   - if answer is yes, how should it be configured ?   - if answer is no, how does DNS delegation work ? Any help will be useful. Thanks and best regards JM
