Can you really use ANY subvol to use with -p. Because if I 1) create a subvol X 2) create a subvol W with the exact same content of X (but created independently) 3) do a RO snap X_RO of X 4) do a RO snap W_RO of W 5) send W_RO to the other FS 6) send -p W_RO X_RO to the other FS I get this: At subvol X_RO At snapshot X_RO ERROR: chown o257-1648413-0 failed: No such file or directory any idea?
