Hi, A basic question on raid0 behavior. When a drive fails/removed in a raid0 array, “mdadm –detail” reports the array state as clean instead of failed. It appears that the drive is whacked out of the array, but that array slot continues to show “active sync” state. I/O to the failed drive errors out. However, it appears that I/O to other drives in the raid0 array would succeed. How would the user know about the array state and potential data loss? Should the array information be cached, drive failure/removals be monitored and checked against the cached information? Could anyone please explain the reason for this behavior of not reporting a raid0 array as failed?
