从Linux内核文档中的Documentation / md.txt中:
clean - no pending writes, but otherwise active. When written to inactive array, starts without resync If a write request arrives then if metadata is known, mark 'dirty' and switch to 'active'. if not known, block and switch to write-pending If written to an active array that has pending writes, then fails. active fully active: IO and resync can be happening. When written to inactive array, starts with resync
因此,不,您不必担心这两种状态;两者都是正常操作。如果您看到了inactive
,那您就不必担心。
