Windows Server 2008 Shrink Volume greyed out

Opdateret den 16. november 2019

This article introduces why Shrink Volume is disabled in Windows Server 2008 R2 Disk Management, and what to do when shrink volume greyed out or doesn't work.

Why Shrink Volume option is disabled

After running server for a period of time, you need to genpartition harddisk. For example, shrink an allocated partition to create new volume for some specific purpose, or krympe D for at udvide C-drevet.

To help accomplish this task, Microsoft added new Formindsk Volume function in built-in Disk Management tool. It is able to krympesystempartition and part of data volumes fast and without losing data. However, some people feedback that Shrink Volume is disabled in Server 2008 Disk Management. Why this could happen?

Årsag: Partition understøttes ikke

Fra Microsoft forklaring kan Shrink Volume kun krympe de partitioner, der er formateret med NTFS or without any file system (RAW). Another common FAT32 and other types of partitions are not supported.

As you see in my server, both Extend and Shrink Volume greyed out for drive E, because it is FAT32.

However, it is not common issue to C drive, because most of system partitions are formatted with NTFS.

Kan ikke krympe

Shrink Volume is activated but doesn't work

Sometimes, Shrink Volume is activated and available, but it can only shrink little space.

Krympende vindue

There's a tip in the Shrinking window - Du kan ikke krympe en lydstyrke ud over det punkt, hvor der ikke er flytbare filer.

For example: there's 40GB free unused space in C drive, if there are "unmovable" files are located in block 3, Disk Management kan ikke krympe C-drev beyond this block to 1 or 2. Therefore, Disk Management only allow you krympende C-drev med fri plads i blok 4.

Ikke flytbare filer

This is the reason why many people feedback that there's little space available when krympende partition in Windows 2008-server.

In this situation, you need to run third party partitionssoftware såsom NIUBI Partition Editor, which can move these "unmovable" files, therefore it can shrink this partition to minimum size if you want.

You won't encounter any issue while shrinking NTFS data volumes in most cases. After getting free Unallocated space, you can create new volume easily. However, if you want to extend other partition with this Unallocated space, Disk Management cannot help you.

Lær why cannot extend volume in Windows Server 2008.

Hvad skal man gøre, når Shrink Volume gråtonet

To shrink FAT32 partition, or shrink a partition to expand other one, you also need NIUBI Partition Editor. Just drag and drop on the disk map, then Unallocated space can be made on either left or right side. This space can be combined to any other partitions in the same disk (except EFI partition in GPT disk).
