We assume that you do not have 3 Gb of unallocated disc space and cannot add new discs.

Personally I wouldn't attempt to reduce a filesystem "in situ". I believe that it is only ever safe to create a replacement filesystem. This is because it can be too difficult to find out the high water mark of a filesystem even where your O/S allows you to re-size filesystems and disc partitions.

If you embark on this, make two "cold metal" backups (I don't mean "tar") of all system partitions (incl. /var) and rehearse recovery on a spare computer before rehearsing the operation on that spare computer.

It may be easier to create soft link under root (or whatever) with the required name of the temporary filesystem and point it to a new directory under /var .

filesystem(7)						 Miscellaneous Information Manual					     filesystem(7)

NAME

       filesystem - event signalling that filesystems have been mounted

SYNOPSIS

       filesystem [ENV]...

DESCRIPTION

       The  filesystem	event  is  generated by the mountall(8) daemon after it has mounted all filesystems listed in fstab(5).  mountall(8) emits
       this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with other activity.

EXAMPLE

       A service that wishes to be running once filesystems are mounted might use:

	      start on filesystem

SEE ALSO

       mounting(7) mounted(7) virtual-filesystems(7) local-filesystems(7) remote-filesystems(7) all-swaps(7)
