NAME
     vxresize - change the length of a volume containing  a  file
     system

SYNOPSIS
     /etc/vx/bin/vxresize [-bsx] [-F fstype] [-g  diskgroup]  [-t
     tasktag] volume new_length [medianame...]

DESCRIPTION
     The vxresize command will either grow  or  shrink  both  the
     file system and its underlying volume to match the specified
     new volume length.  The ability to grow or  shrink  is  file
     system  dependent.   Some file system types may require that
     the file system be unmounted for the operation to succeed.

     Note: vxresize works with VxFS and UFS file systems only.

     In some situations, when resizing  large  volumes,  vxresize
     may take a long time to complete.

     The new_length operand can begin with a plus  (+)  or  minus
     (-)  to  indicate  that  the  new length is added to or sub-
     tracted from from the current volume length.

     The medianame operands name disks to use for allocating  new
     space  for  a  volume.  These arguments can be a simple name
     for a disk media record, or they can be of  the  form  medi-
     aname,  offset  to  specify an offset within the named disk.
     If an offset is specified, then regions from that offset  to
     the  end  of  the disk are considered candidates for alloca-
     tion.

OPTIONS
     -b        Performs the resize operation in  the  background.
               The  command  returns quickly, but the resize will
               be in progress.  Use the vxprint command to deter-
               mine when the operation completes.

     -F fstype Supplies  the  type  of  the  file  system  to  be
               resized.

     -g diskgroup
               Limits operation of the command to the given  disk
               group, as specified by disk group ID or disk group
               name.  The volume operand is evaluated relative to
               the given disk group.

     -s        Requires that the operation represent  a  decrease
               in the volume length.

     -t tasktag
               If any tasks are registered to track the  progress

               of the operation, mark them with the tag tasktag.

     -x        Requires that the operation represent an  increase
               in  the  volume length.  Fail the operation other-
               wise.
