What does NTSTATUS 0xC0210006 (STATUS_FVE_FS_NOT_EXTENDED) mean?

STATUS_FVE_FS_NOT_EXTENDED

Meaning and context of STATUS_FVE_FS_NOT_EXTENDED

Here the file system ends before the end of the volume. This is the inverse kind of layout inconsistency from STATUS_FVE_BAD_PARTITION_SIZE, where the file system appears to exceed the partition recorded in the partition table.

Confirm whether the volume was recently extended or whether the target selection accidentally points to a larger block volume than the intended file system. Check the partition and file-system boundaries before making a storage change; the status is not caused by an incorrect recovery key or a TPM problem.

When a supported resize is actually intended, complete and validate that storage operation first, then retry BitLocker from a stable layout. Mixing encryption conversion with an unresolved resize state makes later diagnostics much harder.
