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().
