And finally,

LVM: what's better to use, lvextend (extends lvol) + fsadm (resizes fs) OR lvextend + extendfs_vxfs?

VxVM: Is it the same commands? lvextend + one of {fsadm_vxfs, extendfs_vxfs}?

extendfs_vxfs and fsadm_vxfs are not unix commands. They are the names of unix "man" pages which give the special syntax of the command in context.

See the following "man" pages for the "top of tree" for LVM and Veritas (VxVM) respectively.

Code:

man lvm
man vxintro

If you don't have the "man" page then check whether you have the package at all.

It always helps to know what Operating System version you have. There has been a move away from LVM towards Veritas (VxVM) over the last 10 years or so.
We are unclear whether you are looking at an existing mature system or what.

Take a look at the contents of /etc/fstab .

Logical Volume adm Filesystems size parameters are in power of 2 notation. (1024 bytes = one kilobyte). There is however nothing to stop you creating say a 10 Gb filesystem. Hope I understood your question.

Beware that there are overheads in Journalling File Systems and the actual free space in a filesystem will be a fraction lower than you may expect.

I am unwilling to suggest LVM or VxVM commands in this context because we know nothing about your environment.

I want to resize my filesystem partitions. Reason is that I have 11GB of disk space unused by Unix which divvy reveals. Is there a way I could resize my filesystems without doing a reinstallation. The secondary problem is that the boot image is too large for a diskette (5MB). I'm running SCO...

I want to run a script that changes the size of the window from which it's been started.

Parition Resizing

Is there a way to take space from the /opt slice (/dev/dsk/c1t0d0s5) and then put it in the /var (/dev/dsk/c1t0d0s1)? In theory, I should be able to ufsdump /opt and /var to another drive. Use disk label to resize those two slices (ex. take 10G from opt and add to /var) and then newfs and dump back...

Tk_SetGrid(3)                                                  Tk Library Procedures                                                 Tk_SetGrid(3)

__________________________________________________________________________________________________________________________________________________

NAME

       Tk_SetGrid, Tk_UnsetGrid - control the grid for interactive resizing

SYNOPSIS

       #include <tk.h>

       Tk_SetGrid(tkwin, reqWidth, reqHeight, widthInc, heightInc)

       Tk_UnsetGrid(tkwin)

ARGUMENTS

       Tk_Window tkwin (in)              Token for window.

       int reqWidth (in)                 Width in grid units that corresponds to the pixel dimension tkwin has requested via Tk_GeometryRequest.

       int reqHeight (in)                Height in grid units that corresponds to the pixel dimension tkwin has requested via Tk_GeometryRequest.

       int widthInc (in)                 Width of one grid unit, in pixels.

       int heightInc (in)                Height of one grid unit, in pixels.
_________________________________________________________________

DESCRIPTION

       Tk_SetGrid  turns  on  gridded geometry management for tkwin's toplevel window and specifies the geometry of the grid.  Tk_SetGrid is typi-
       cally invoked by a widget when its setGrid option is true.  It restricts interactive resizing of tkwin's toplevel window so that the  space
       allocated to the toplevel is equal to its requested size plus or minus even multiples of widthInc and heightInc.  Furthermore, the reqWidth
       and reqHeight values are passed to the window manager so that it can report the window's size in grid units during interactive resizes.  If
       tkwin's  configuration changes (e.g., the size of a grid unit changes) then the widget should invoke Tk_SetGrid again with the new informa-
       tion.

       Tk_UnsetGrid cancels gridded geometry management for tkwin's toplevel window.

       For each toplevel window there can be at most one internal window with gridding enabled.  If Tk_SetGrid or  Tk_UnsetGrid  is  invoked  when
       some other window is already controlling gridding for tkwin's toplevel, the calls for the new window have no effect.

       See the wm manual entry for additional information on gridded geometry management.
