Go read the raid wiki. https://raid.wiki.kernel.org/index.php/Linux_Raid Especially replacing a failed drive https://raid.wiki.kernel.org/index.php/Replacing_a_failed_drive And please - can you get ddrescue's error log that it mentions and email me a copy. If you've got some Perl or Python or shell skills, maybe you could even write that script it mentions (which is described in a bit more detail in programming projects https://raid.wiki.kernel.org/index.php/Programming_projects) Otherwise I'll try and write it - might be a good way of learning Python :-) but at the moment I think I'm learning by jumping in out of my depth, so we'll see how far I get :-) Cheers, Wol -- 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
