That explains an issue I had when creating a brand new raid6 and it failed to start a sync as I expected it to... I probably went round the house to "fix" it and ended up using a "missing" then adding the missing drive which started the sync. I guess its one of the problems, that isn't, that "just happens" when you start to keep too close an eye on things, such as a "watch proc/mdstat" in another window where as before I probably would have just created it, added a file system, and been none the wiser :-/ > > Just perform pvcreate on the array as you intended, and that'll switch > the array to rw (and start the resync). > > HTH, > > Phil -- 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
