Refs file system is not supported on this device

When creating a new storage space volume even Windows 8 gives the option to use ReFS. Another thing I wanted to try was snapshots. Snapshots work with ReFS too. It is possible to access snapshots via symbolic links. For example, small ReFS volumes should be much less impacted by these bugs. For example, support for built-in deduplication on ReFS volumes. This made no sense to the IT community because both unsupported SAN LUN and fully supported basic disks are absolutely identical block devices from a file system perspective, so some additional information is available at Ignite.

The technical reason behind this note appears to be the fact that Microsoft Support has seen some SAN storage devices which do not honor the flush command, which is extensively used by file systems and apps to guarantee that the data has landed to the disk and is consistent.

So this is not really a ReFS-specific issue. But from Microsoft perspective, they cannot possibly test every RAID controller out there, so they opted for such a blanket statement.

Dec 1, 32 Any idea if it's possible to install the latest Win10 build on ReFS somehow? I tried a fresh install but the installer will only let you install to a NTFS filesystem. And then the remaining space as Another ReFS partition.

It actually was possible to "trick" the installer to try doing the installation: Create the first small partition, next the large one and format it as NTFS. But it fails after a couple of seconds when trying to copy the files Skaendo MDL Addicted.

Sep 23, In addition to providing resiliency improvements, ReFS introduces new features for performance-sensitive and virtualized workloads. Real-time tier optimization, block cloning, and sparse VDL are good examples of the evolving capabilities of ReFS, which are designed to support dynamic and diverse workloads:. Mirror-accelerated parity - Mirror-accelerated parity delivers both high performance and also capacity efficient storage for your data. To deliver both high performance and capacity efficient storage, ReFS divides a volume into two logical storage groups, known as tiers.

These tiers can have their own drive and resiliency types, allowing each tier to optimize for either performance or capacity. Some example configurations include:. Once these tiers are configured, ReFS uses them to deliver fast storage for hot data and capacity-efficient storage for cold data:.

For Windows Server deployments, mirror-accelerated parity is only supported on Storage Spaces Direct. We recommend using mirror-accelerated parity with archival and backup workloads only.
