[NFS-Ganesha-Devel] Re: Question about recovery on Ceph FSAL

Hi Daniel, I agree with your thought, but the implemation of FSAL_CEPH seems to be different with yours. Here is the design of it. https://www.mankier.com/8/ganesha-rados-cluster-design I also checked the code. When one of servers enter a grace period, it will call rados_cluster_read_clids() to read culster wide variable C and R. Only if R==0, the whole culster enter grace period. If so, the cluster goes grace period when reboot, not when crash. It also seems no interface for pacemaker/corosync to get information and put the cluster into grace period. Thanks, Marvin
