I setup a 2 MDS cephfs and copied some data into it, deleted some directories whose authority is MDS.1, then shutdown MDS.1. Most patches in this series are obvious. The two snaprealm related patches are workaround for a bug: replica inode's snaprealm->open is not true. The bug triggers assertion in CInode::pop_projected_snaprealm() if snaprealm is involved in cross authority rename.
