Information About This Version Known Problems and Workarounds • Files exported from an (Episode) LFS will behave as if POSIX_CHOWN_RESTRICTED is true. This means that only a privileged user can change ownership of (chown) a file. In general, the file owner is not privileged, and cannot chown a file. This differs from the behavior of other HP-UX file systems (HFS, VxFS, NFS) and from a DFS exported UFS file, all of which allow file owners to chown files they own. A privileged user is either the DCE network root identity or a user specified in the group specified by the -admingroup option of the fxd command that starts a DFS file server. By default, that group is subsys/dce/dfs-admin and its members include cell_admin. • A daemon process needs appropriate DCE credentials to access files and perform its duties; or the files need to have the correct ACLs to allow the daemon to access it. • DFS behaves like NFS soft-mount by default if a file server becomes unavailable. (See the cm sethardmount command in the "Installing and Configuring Enhanced DFS 3.0" chapter for information about setting hard mount semantics.) • DFS file locking works just like local file locking via lockf() or fcntl(). 28
