Why not experiment with loop devices on files and find out? But yes: you can grow to a degraded array providing you specify a --backup-file. However I don't recommend it. I would never recommend having a degraded array by design. It should only ever happen due to a failure, and should last only until you can get a replacement rebuilt. Remember that a degraded raid5 has a greater risk of data loss than a single drive. > > > PS: the fact, that degraded array will be unsafe for the data is an > intented motivating factor for buying next drive ;) :-) NeilBrown - 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
