Summary

The amount of free disk space on the logical disk volume has exceeded the threshold. System performance may be adversely affected and the ability to add or modify existing files on the logical disk volume may not be possible until additional free space is made available.

Causes

When existing files grow in size and the new files are added, the free space is taken up on a logical disk. When the amount of free space on the logical disk falls below the threshold, the state for the logical disk will change.

Resolutions

To increase the amount of available disk space, do one or more of the following:

  • Run Disk Cleanup to gain more free space on the disk.

  • Back up and remove files, or delete unnecessary files from the disk.

  • Move files to another disk or to offline storage.

  • Purchase additional storage or switch to a larger disk.
