Greetings,

Considering that double disk failures do happen, what would happen if an array group in a DP pool had a double disk failure?  What sort of horrible things are likely result from that?

For example, just say I have 12 x 300 GB Array Groups in my USP V and bingo, two disks in one of the AG's die together.  Would that mean my 24 TB DP pool is pretty well useless?

Double disk failures were bad enough with LUSE but this concept of large amounts of storage going missing is a bit worrying..

Do I need to worry?

Stephen
