Microsoft has released a new white paper, discussing best practices and guidance for sizing NTFS volumes and some details on CHKDSK execution times on Windows Server 2008 R2.
When planning Windows file server deployments, we are often asked questions such as "How large can I make my volumes?" or "How long will it take to repair a volume?" This white paper helps answer these questions.
This document provides best practices and guidance when sizing volumes and Chkdsk execution times. This guidance helps you design a manageable system using Microsoft Windows operating systems. It also provides guidelines to reduce downtime due to Chkdsk execution time in the event of volume corruption
"NTFS self-healing is a feature introduced in Windows Vista and in Windows Server 2008 to reduce the need to run CHKDSK. NTFS self-healing attempts to fix certain corruptions encountered during normal operation, which significantly reduces the frequency of NTFS marking the volume dirty. When NTFS can self-heal, it will not have to perform CHKDSK on the volume during system startup. Self-healing fixes corruptions while the volume is still online, which increases the overall availability of the systems."
