Also a long time since I used VMS. I do remember that one issue I
sometimes faced is that the free block count on a disk device would
sometimes not match up with reality (might be the issue you face). To
correct this we would use copy/allocate command... something like...
$ copy/allocate=nnnnnn junk.dat junk2.dat
where junk.dat was a small file and "nnnnnn" was some large number to
force the command to fail. This had the side effect of resetting the
free block count for the device.

Ken.

Dont you have to kill the process accessing the file before it can be
resized? show dev/files and kill the processes that is accessing the
file? Its been a few years since I used VMS myself...

I have not touched a VMS system for 20 odd years. One of the
things I did was to shrink the size of the undo tablespace from 2770 MB
to 1024 MB. When I issue the VMS command
show device/full <device_name>
the number of free blocks is no different than before. What
needs to be done to get the space released.
