la la land

[Ron Peterson]

Not strictly a linux question, but I'm hoping someone on this list might
have some insight.  How can a file disappear and then reappear again?  I
know that sounds ridiculous, but look at the following:

# ls -li passwd ; date
63444 -rw-r--r--   1 root     system    967593 Jan 17 15:20 passwd
Wed Jan 17 15:38:26 EST 2001
# ls -li passwd ; date
ls: passwd not found
Wed Jan 17 15:38:27 EST 2001
# ls -li passwd ; date
63444 -rw-r--r--   1 root     system    967593 Jan 17 15:20 passwd
Wed Jan 17 15:38:28 EST 2001
# ls -li passwd ; date
ls: passwd not found
Wed Jan 17 15:38:28 EST 2001
# ls -li passwd ; date
ls: passwd not found
Wed Jan 17 15:38:29 EST 2001
# ls -li passwd ; date
63444 -rw-r--r--   1 root     system    967593 Jan 17 15:20
passwd         

This makes the problem go away.  For awhile anyway.
  
# mv passwd p
# cp p passwd
#
#
# ls -li passwd ; date
88967 -rw-r--r--   1 root     system    967593 Jan 17 15:38 passwd
Wed Jan 17 15:38:55 EST 2001
# ls -li passwd ; date
88967 -rw-r--r--   1 root     system    967593 Jan 17 15:38 passwd
Wed Jan 17 15:38:56 EST 2001
etc.

This is on Tru64 on a DS20.  OS bug?  Filesystem corruption?  Any ideas
for further diagnositic work?
