Disposition: 9-5-84.  Fixed a long time ago, before the Carol release.  There was a bug in the volume allocation map code which caused the free page count to get out of whack from time to time when allocating pages.  At the same time, I created a workaround': call (DISKFREEPAGES volumeName T), and it will recompute the number of free pages.  -- Tayloe.'

To': LispSupport.PA'
After repartitioning the physical volume into 3 lisp parts. and a'
BootLisp and then making Lisp3 into DSK and running lisp (MAKESYSDATE ='
9-Apr-84 19':08':22) in the partition called Lisp, I started copying files'
from a floppy to DSK.  First, the number of pages "allocated" to the'
partition I was running in (Lisp) went from 16200 to -1, then later to'
-32769, and then back to -1 (where it is right now).  Somewhere in there'
I also deleted some files from DSK and did a couple of DIRs on both the'
floppy and DSK devices (sorry I don''t remember the exact sequence, but'
that is all I was doing -- copying files with some DELFILEs and'
DIRECTORYs in the middle).  Sometime after the allocation went to -1 the'
second time, the number of "free pages" also went to -1 in the Lisp'
partition.  That is currently where it stands.  Mind you this is the'
information displayed in the VOLUMEDISPLAY window -- the system is still'
running fine as best as I can tell other than that.  If there is a'
question I didn''t answer, please call or send a message.'
Good Luck,'

my previoous message about the volume display having fun numbers in it'
for the volume I was running in as I moved files from floppy to DSK said'
that everything seemed to be fine.  I lied, when I finally did a logout'
I died in \DFSEventFn with an illegal arg to ELT.  '

I have no idea where this comes from.  I could write a function to recompute free pages from scratch, and so rerail the free page count when it gets haywire, but that is nontrivial, so I think I''ll let it wait till the next release.'
