Hopefully someone will have seen and solved this issue before! I have a Perl script environment that kicks off 3rd party tools and watches the log files of those tools to determine pass/fail. It all works fine unless the log files are being dumped to a RAID disk. In that case, the perl file tests (-e, -R) always fail. The files being tested do exist, but for some reason Perl can't see them.
I understand that RAID creates a virtual disk which the application sees? Perhaps this is confusing things. I'm stumped to be honest.
