syncids - fix or verify file owners in a file system
usage: syncids [-a] [-l] [-v] volume-pathname
DESCRIPTION
In a Domain system, every user (and group) is identified by a 64-bit
identifier that is unique across all Domain users (and groups) in both
space and time. However, UNIX interfaces that take user and group IDs as
arguments expect integers that may be unique only within a given file
system. The Domain file system stores both forms of identifier with each
file. The 64-bit UIDs are used for checking access rights, since there
can never be conflicts even if two networks are merged, or a workstation
moves from one network to another.
syncids is a program that should be run whenever network registries are
merged, or a node is moved between networks having different registries.
It ensures that the UNIX owner IDs match the unique owner IDs for every
object on the logical volume.
OPTIONS
-a List the name and owner information for each object as it is
processed.
-l Only list information about objects for which UNIX owner IDs are
incorrect.
-v Verify only; do not actually modify the owners of any objects. This
option implies -l. If the -a option is also given, then information
will be printed about every object on the volume.
