Hi, When creating a ceph cluster, a failover domain is created, and by default it uses host as a minimal domain, that domain can be modified to chassis, or rack, ...etc. My question is : Suppose I have three osd nodes, my replication is 3 and my failover domain is host, which means that each copy of data is stored on a different node. What happens when one node crashes, does Ceph use the remaining free space on the other two to create the third copy, or the ceph cluster will run in degraded mode, like a RAID5 which lost a disk. Regards.
