in reply to Perl files tests fail on RAID disk

      It all works fine unless the log files are being dumped to a RAID disk.

I am seriously doubting this is a Perl issue per se but I'll play along for a moment.

  • What errors are you seeing?
    • It all works fine unless the log files are being dumped to a RAID disk.
    what exactly does that mean?
  • What operations are you performing to the RAID environmnt?
  • What kind of RAID?
    • Hardware?
    • Software?
    • SAN?
    • ?????
    • Bug Spray?
  • What is the operating environment?
Honestly Perl has no concept of a difference between files on JBOD or any other storage medium and RAID. However, at the systemic level there could be differences.

    It might also be an issue attributable to network or filesystem. Some filesystems like AFS or NFS are problematic, and maybe this "RAID device" has interesting behaviour in such cases.

      Hi,
      For the detailed RAID questions, I am having to chase up with the person who set it up for me as I know little or nothing about it. However your questions have shown me the questions I need to ask.
      Thanks

      AFS has some particularly interesting behaviors. You can "appear" to have permissions but not really have permissions to write in some cases.
