我正在备份存储在 zpool 中的数据，该 zpool 由一个带有 2 个硬盘的 raidz vdev 组成。在这个操作过程中，我得到了校验和错误，现在状态如下：
pool: tmp_zpool
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.
