Any time you fall back on ddrescue to make one of those 34, you are ensuring that some data is lost. But yes, that would otherwise work. The 2/3 recovered disk is only useful in this (use ddrescue to get as much of the missing disk as possible). If you can get to 35 of 36 original disks, even with scattered errors, you could complete a check scrub to make 35 good disks. With timeout mismatch, you'll have to override the kernel timeouts for all devices, so such a scrub would take a very long time, but would recover everything. > Martin 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
