Yesterday we tried a restore of the test data disk, and it
stalled (abort or continue?) when it ran out of disk space. It was
already showing 96% full before the restore, and vdump had made a
3GB temporary file (_vrestore_tmp.55978) taking up much of the
remaining space.
It has been suggested that we should not have to put up with this
enormous temporary file, and it would interfere unreasonably in
a real disaster recovery situation.
My argument is that the temporary file is probably unavoidable,
that when a disk is already full the restore might have to
be done in stages and maybe delete some stuff first, and that
no filesystem should ever rise to 90% full and they should not
routinely sit avove about 75% or 80%.
Am I on the right track with these recommendations not?
This is Tru64 5.1a, and maybe the improved AdvFS can tolerate
more bloat than prior versions could.
