質問 # 15
Which three are features of the btrfs file system?

A. Online resizing
B. Automatic defragmentation
C. General-purpose volume manager
D. Copy-on-write metadata
E. Efficient storage for small files
F. Cluster file system
G. Block devices mirroring

正解：A、B、D

解説：
* Option B (Correct):Btrfs uses a copy-on-write mechanism for both data and metadata, which ensures that the file system is more resilient to crashes and data corruption.
* Option E (Correct):Btrfs supports online resizing, meaning that you can change the size of a mounted Btrfs file system without unmounting it.
* Option G (Correct):Btrfs automatically defragments files in the background to maintain performance.
* Option A (Incorrect):While Btrfs does support mirroring, it is not strictly block device mirroring in the traditional sense like RAID; it uses a different approach to redundancy.
* Option C (Incorrect):Btrfs is not a cluster file system; it is designed for local file systems.
* Option D (Incorrect):While Btrfs can store small files efficiently, it is not its primary design goal compared to other file systems optimized specifically for small files.
* Option F (Incorrect):Btrfs is a file system with integrated volume management capabilities but is not a general-purpose volume manager like LVM.
Oracle Linux Reference:Refer to:
* OracleLinux 8: Btrfs File System
* man btrfsfor features and management.
