This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

This really belongs on serverfault.

Before you do anything check the status of your backups.

Assuming you have enough working disks in the array to rebuild: replace the faulty disk with another identical one, and perform a rebuild.

Suggest you read: Common mistakes while performing RAID recovery
