Then you can at least use Othello or Tajo to clean up your disk by erasing {DSK}.  SETVOLUMETYPE currently bombs out with a Non-numeric arg error.'

1)  Put someone in charge of the Dlion file system, even if they are not actively developing it.  Several times I have bombed with file system problems and run around looking for someone to look at the state of the machine.  No one has ever been willing to take responsibility for this task.  I have tried to debug the code by myself.  While I haven''t found any major solutions, I can point out a number of bugs in the DLIONFS code I have discovered this way.  It seems like a knowledgeable person doing this task might gain a lot of valuable insight just by looking at various problems when they occur.'
'
2)  Assign someone to take a day and write a 4-page memo on the structure of the DLion file system and to comment the code as best as possible.  I would be willing to track down problems to the best of my ability.  But I have a hard time making heads or tails of the code as it now stands.   '

I''m having a problem trying to set up my DSK volume to be Interlisp-D accessible.  I''m using three partitions on my 42 MB disk, Diagnostics (type = debugger) 30000 pages, DSK (type = nonPilot) 20000 pages, and Lisp (type = normal) which takes up the rest.  The sysout I''m starting from is found on {Rosebowl}<lisp>carol>full.sysout.  After that I load {phylum}<Lisp>Library>DLIONFS.DCOM.  Next, I call (MKDIR ''DSK).  This is where it goes wrong.  I see "Opened local disk volume {Diagnostics}" printed in the prompt window, then I get a break window with the message "8935936 - ILLEGAL ARG."  Doing a BT! reveals':'

Do I have my disk partitioned correctly?  I''m not sure if the types are right.  Please don''t suggest that I use the sysout up on Phylum, because that takes generally over an hour to bring down.  Any ideas?'

My impression is that your DSK volume should be of type normal.  DLIONFS is really supposed to provide you with a pilot-compatible volume, that''s my reasoning.  Not that I really think it IS pilot compatible, but....'

Because of reliability problems, the DLionFS package is being withdrawn from the group of Interlisp Library packages.  All copies have been archived and deleted from {phylum}<Lisp>Library>.  If anyone is depending on these files, please contact Sannella.pa.'
'
It is currently a priority item in the Interlisp support group to produce a reliable 1108 local file system.  As soon as we have one that is usable, it will be released.'

Below is a recurrent problem with the DLIONFS.  It happens to us 4 or 5 times a day when we use the file system all day.  Leads to a 9318 due to uninterupptableness of the Allocate routine.  Looks to me like  \VAMAllocateSpace never checks to make sure that the space sent back by \VAMFindSpace (bound to the variable PossibleSpace) is sufficient for its needs.  It always bombs in IGREATERP when PossibleSpace becomes NIL.'
