Well, I can't have that go wrong because I assemble all of them :) One thing I would like to know, though: I screwed up construction of one of my arrays and forgot to give it a name, so every array with a V1 superblock has a name *except one*. Is there a way to change the name after array creation? (Another overloading of --grow, perhaps?) (I'm still quite new to md so rather queasy about `just trying' things like this with active arrays containing critical data. I suppose I should build a test array on a sparse loopback mount or something...) > I would like an md superblock to be able to contain some indication of > the 'name' of the machine which is meant to host the array, so that > once a machine knows its own name, it can automatically find and mount > its own arrays, ... and of course you could request the mounting of some other machine's arrays if you cart disks around between machines :) Seems like a good idea. -- `Come now, you should know that whenever you plan the duration of your unplanned downtime, you should add in padding for random management freakouts.' - 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
