[rrd-users] Re: Strange RRDTool Image File Behavior

[Schroeder, Dennis]

Bruno,

Actually, the programs are working fine (for the most part).  This is NOT
happening on every graph file.  There are currently only 12 files out of
over 1000 that are having a problem, the rest update (get replaced) when the
program runs without a problem.

This seems to be some kind of strange permission thing, or the files are
corrupt or something.  It's very strange when I delete them, hit 'refresh'
and they are still there (never deleted).  If I go directly to the server, I
can delete them and they are really gone.

Hi Dennis

The error message says "Opening '../filename.gif' for write: Invalid
argument"

I think you are using the wrong "slash" on NT.  You should use
"\filename.gif" not "/filename.gif"

Let me know what you find

RRD shows the following error when trying to create the new image file:

"Opening '../filename.gif' for write: Invalid argument"

This doesn't halt my PERL program, it continues on to the next step.

When I attempt to manually delete the files, they will disappear from
Explorer (until I "refresh" or re-run my search).  The file is not being
recreated, it still has a modify date that is not current.  If I try to
delete from a CMD prompt, I get no errors, but when I DIR again, it's still
there.

The permissions on the directory where all of the image files are being
stored are as follows:

Domain Admins: Full Control
My Account: Full Control
Everyone: Read

It was intentionally setup this way because of the access by the user
community to this server...I didn't want just anyone to have more than
"read" permissions.

"Cannot be replaced".  Does this mean that RRDtool stops with an error?

"reappear".  Could it be that they *are* recreated?  If this happens
right away, could there be a tight loop where RRDtool is called over
and over again?

Is this true?  It works this way for root on unix but IIRC you don't
need to permit the admin group anything if you don't want?  The admin
may steal your file (change ownership) but this doesn't mean the file
can be read/changed/whatever prior to that?
