NAME
     setext - set extent attributes (VxFS)

SYNOPSIS
     setext [-e extentsize] [-r reservation] [-f align] [-f contig]
            [-f noextend] [-f trim] [-f chgsize] file

DESCRIPTION
     setext allows space to be reserved to a file, and a fixed extent size
     to be specified for a file. The file must exist.

OPTIONS
     -e extentsize  Specify a fixed extent size. The extent size is speci-
                     fied in file system blocks.

     -r reservation  Preallocate space for a file. The reservation is
                     specified in file system blocks.

     -f align        Specify that all extents must be aligned on
                     extentsize boundaries relative to the start of allo-
                     cation units.

     -f contig       Specify that the reservation must be allocated con-
                     tiguously.

     -f noextend     Specify that the file may not be extended once the
                     preallocated space has been used.

     -f trim         Specify that the file is to be trimmed to the current
                     file size upon last close by all processes that have
                     the file open.

     -f chgsize      Specify that the reservation is to be immediately
                     incorporated into the file. The file's on-disk inode
                     is updated to with size and block count information
                     that is increased to include the reserved space.

                     chgsize is restricted to the superuser.

NOTE
     Multiple flags may be specified by specifying multiple instances of -f
     on a command line.
