解答

聚合的状态为parity uninit'd

Aggr State Status Options
aggr0 online raid4, aggr root
parity uninit'd!    ->

以上输出表示磁盘已被虚拟化清零。

由于parity uninit'd!可靠的 RAID 和 Write Anywhere File Layout ( WAFL )操作需要完全初始化(清零)磁盘、因此用户环境绝不能使用虚拟初始化的磁盘和聚合运行。非奇偶校验磁盘出现任何错误都可能导致发生崩溃和/或数据损坏。

  1. 正确初始化所有磁盘并创建新聚合。
  2. 如果仍需要数据、请将其复制到新创建的聚合。
  3. 删除parity uninit'd!聚合。

注:如果根聚合parity uninit'd处于状态、则此后创建的每个 aggr- 也将是“奇偶校验 uninit ”,而不管磁盘是否已被干净擦除、每个磁盘 0 都将是假的零。在这种情况下,只能使用导入外部聚合来创建正确初始化的聚合。
