 Punctured Stripe on RAID 5 Array
RAID, RAID 5, RAID Array, Storage in 2010
We have been having massive problems with a storage array (Dell md3000i). The issue has been escalated to the highest levels of Tech Support, at which point they advised us that we have a "punctured stripe" on our array. The prescribed resolution is to vacate, wipe-out and re-build the array, then re-populate. I am wondering if there are other known & proven ways to resolve a punctured stripe (?) Also, Dell advised us that the problem may have occurred several months ago, based on analysis of error logs, etc. I am wondering if there are early warning signs of a punctured stripe, as the symptoms often indicate drive or controller issues at their initial stages.

Software/Hardware used:
Dell, RAID 5 Array

This <a href="http://blog.integrii.net/?p=24">blog post</a> talks about it a little, and someone gives some info about how to correct the problem without wiping the array. It appears theres some CRC checks that can be enabled to prevent this although not much detail is gone into this concept in the post.
