AFAIK, the mv command treats filesets as separate filesystems, even when sharing the same inode space.

I have an independent fileset fs1 which contains data that I would like to move to a newly created dependent fileset fs2. fs1 and fs2 are sharing the same inode space. Apparently calling mv is copying the data instead of just moving it. Using strace on mv prints lines like renameat2(AT_FDCWD, "subdir1/file257", AT_FDCWD, "../filesettest/subdir1/file257", 0) = -1 EXDEV (Invalid cross-device link) Is there an efficient way to move the data between the filesets fs1 and fs2?
