As comming to "terms" working with mdadm took me a while, I'll add my current "translations" of the actions to the discussion: 1) The "failed" state is the state a member that failed or is missing gets, while it can stay listed in mdstat. 2) To "unbind", "unlist" or "dismiss" a member from the md device stats is currently called to --remove it. In particular you can "unbind", "unlist" or "dismiss" failed or detatched members with --remove failed/detached. 3) A safe way to "lock-out" or "really remove" members from udev/--incremental assembly is not available yet AFAIK. (--zero-superblock on mirror members makes the md device content detectable/available directly) IMHO the ones mentioned first could seen as implied by those mentioned later. I am unclear why --incremental seems to require a device to be unbound first (--removed) in order to re-add it after it failed. IMHO it could do it itself if it is really necessary without bothering the user. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
