Description

This error indicates that an ACFS snapshot deletion was successful, but the associated disk storage could not be entirely reclaimed. Although the snapshot is gone, some underlying disk space remains occupied, requiring a manual cleanup operation. It typically occurs when the file system's metadata or storage allocation is not perfectly aligned after the delete.

Error Message

Known Causes

3 known causes
⚠️
File System Metadata Inconsistency
The file system's internal records about allocated space may not have been fully updated after the snapshot deletion, leading to orphaned blocks.
⚠️
Fragmented Storage Allocation
Highly fragmented storage can sometimes prevent the efficient reclamation of contiguous blocks, even after data is marked for deletion.
⚠️
Concurrent Operations
Other ongoing I/O operations or background processes might temporarily lock or interfere with the immediate release of disk blocks.
