I seeking advice on repairing a broken RAID 5 Array.I have a 6 disk RAID 5
array that lost a second drive.

There are a number of commercial-ware products the report the ability to
repair the array.  I'm not sure of their abilities and secondly they all
seem windows NTFS focused.  What may complicate the is issue is the
filesystem is XFS.

There are a few folks who have repaired their arrays by dd'ing the
individual disk to  images files and rebuilding from there.  I like to hear
anybody else's experience with repair broken arrays.  Any tools (commercial,
open source, shareware), processes or any other good's and bad's you might
have experienced.


Thanks
