VRTSvxfs
vxfs_vol_resize()
changes the amount of space available to a file system
in a component volume
specified by the volume
volname.
The size of the new component volume must be at least
newsize
(specified in bytes).
The file descriptor
fd
can be any file in the file system.
In the current implementation,
if there is data in the part of the volume that is shrinking,
the resize operation will fail.
vxfs_vol_resize()
returns zero on success,
non-zero on failure.
