Hello Pradeep, Ranjit, As far as I know, you need to have an NFS primary storage and OOBM configured. There is a PR that provides a solution to have HA for RBD, but it's not merged yet - https://github.com/apache/cloudstack/pull/5862.
I hope the links below will help you https://docs.cloudstack.apache.org/en/latest/adminguide/reliability.html#ha-enabled-hosts https://cwiki.apache.org/confluence/display/CLOUDSTACK/Out-of-band+Management+for+CloudStack https://www.shapeblue.com/host-ha-for-kvm-hosts-in-cloudstack/#Host-HA_on_KVM_host Best regards, Slavka On Fri, Dec 2, 2022 at 9:02 AM Ranjit Jadhav <ranjeet.jad...@gmail.com> wrote: > Hello Guys, > > We are also struggling with this HA thing any guidance will be highly > appreciated. > > Regards, > Ranjit > > On Thu, 1 Dec 2022 at 20:50, pspa...@hotmail.com <pspa...@hotmail.com> > wrote: > > > Hi, > > I have build new infra with Ceph storage everything working well. > > But VMs HA not working.
