How can I tell what AFR version a cluster is using for self-heal? The reason I ask is that I have a two-node replicated 3.7.8 cluster (no arbiters) which has locking behavior during self-heal which looks very similar to that of AFRv1 (only heals one file at a time per self-heal daemon, appears to

Thanks for your reply. Do I need check all files in /var/lib/glusterd/*? Must all files be same in A node and B node? I found that the size of file /var/lib/glusterd/snaps/.nfs01722f42 is 0 bytes after A board reboot. So glusterd can't restore by this snap file on A node.
