dtrace discuss - Sep 2007 - ghost files or dtrace error?

Hi all,

I have a problem with IO''s against a file that doesn''t exist.
So I figure either I messed up, it''s a dtrace feature or something
weird is going on.
I''m running rwsnoop (from the excellent toolkit) and seeing this...

bash-3.00# [b]/usr/local/dtrace/rwsnoop[/b] 
  UID    PID CMD          D   BYTES FILE
50000  13468 oracle       W    2048
/sb/sys5/oracle/product/9.2/rdbms/audit/ora_968.aud
50000  13468 oracle       W    8192
/sb/sys2/oracle/admin/TDEP2/audit/ora_22796.aud
50000  13468 oracle       W    4096
/sb/sys5/oracle/product/9.2/rdbms/audit/ora_968.aud
50000  13468 oracle       W    2048
/sb/sys5/oracle/product/9.2/rdbms/audit/ora_968.aud
50000  13468 oracle       W    2048
/sb/sys5/oracle/product/9.2/rdbms/audit/ora_968.aud
50000  13468 oracle       W    2048

50000  13476 oracle       W    2048
/sb/sys2/oracle/admin/TDEP2/audit/ora_861.aud
50000  13476 oracle       W    1024
/sb/sys2/oracle/admin/TDEP2/audit/ora_861.aud
50000  15942 oracle       R      17 <unknown>
50000  15942 oracle       W     106 <unknown>

bash-3.00# [b]ls /sb/sys5/oracle/admin[/b]
/sb/sys5/oracle/admin: No such file or directory

those unknowns are from vxfs (haven''t come closer on this yet either),
but my question is how come there is io files that doesn''t exist. A
theory I had was that, the pid 13468 is the dbwriter for TDEP3 a fairly busy
database and somehow the vnodes(?) got messed up what seems to be auditfiles is
actually the databasefiles.
Could this even happen? Any other ideas? 

cheers,

//Mike

Getting lots of email touching various ideas about this, but it seems I need to
clarify one thing.

/sb/sys5 does not exist anymore (neither does /sb/sys2 for that matter) and the
disks have been removed. So my problem is why do they show up at all?
So if anyone has an idea or want me to run a different command let me know and
I''ll do it.

//Mike
