Hi, Could we have a config setting for removing the bad blocks list on assembly? I'm aware that one could put: CREATE bbl=no in mdadm.conf and then newly created arrays won't have a bad blocks list. But in many cases, system arrays are created before an mdadm.conf exists, so they get a bbl. So, to remove a bbl I know that you have to stop the array and assemble it like: # mdadm /dev/mdX --assemble --update=no-bbl Again, for arrays with the actual system on it this is rather inconvenient. Even having to have some downtime of the service to do this is not great. So how about a config option telling mdadm to remove empty bbl the next time arrays are assembled? If there is a bbl with entries in it then it could warn and not remove it (so no force). Cheers, Andy
