Dear develops, I find that SNAPDIR means a special object in ceph. It is a read-only object since if a op write want to modify SNAPDIR object, it return -EINVAL immediately. But I cannot find when we need to create the SNAPDIR object? and what is used for? Based on my understanding, ceph snapshot is realized by snap_set Xattr and snapperMapper in omap. It does not cooperate with SNAPDIR object, so I am puzzled. Can anyone provide some guides to understand this?
