[comp.sys.xerox] MP Code 0935 after failed SYSOUT

ajcole@ai.leeds.ac.UK (Andrew J Cole) (08/31/88)

1186 running Koto 2.02

A SYSOUT failed to complete with a "HARD DISK ERROR" (happens fairly
frequently with no obvious pattern & the disgnostics are happy with
the drive) and on this occasion seems to have corrupted the LispFiles
"directory".  SCAVENGEDSKDIRECTORY falls over with the same error.
SystemTools gives an immediate 0915 when LispFiles is selected from
the Volume Menu & Scavenge from the Installation Utility eventually
gives an 0935.

Now the question - do other people have similar difficulties creating
(& or copying) SYSOUTs?  In our case similar HARD DISK ERRORs have always
afflicted our machines invariably only when making SYSOUTs or copying them
between machines.

Cheers,

	Is your lispfiles volume larger than 16 megabytes?  There was a bug in
Koto that sometimes signalled spurious hard disk errors when such a large
lispfiles volume was in use.  We were told by AIS to upgrade to Lyric, and as
I recall, that fixed the problem.  (For unrelated reasons, our machine that
had this problem is no longer partitioned with such a large lispfiles volume.)

Our largest one is 30000 pages.

I've not heard that one before, but it so happens that I always set up the
profile after initialisation since we sysin across the ether.

When that happens I've always managed to recover with scavenges, sometimes
having to fix up the break in SCAVENGEDSKDIRECTORY,in this case there was
plenty of space for the sysout.

Thanks for the responses, to recover with the minimum fuss I eventually
erased the LispFiles volume using the installation tool, reinstalled the
Koto systemtools etc - at least I didnt need to repartition & the other
LispFiles volumes were OK.
