Also one of my cheap "4 port sata" cards doesn't identify port number on the device and while it was possible to work it out by tracing device serial-sata cable-socket then mentally comparing sd*-device serial=port it was something I was putting off as "a pain" but also being bugged by my md member devices numbers being out of whack with my sd designations: sda[4] sdb[2] sdc[1] sdd[3] and with 12 devices the last thing you want when something is failing is to have to hunt around to work out which device physically relates to which os identified device. With this I can now easily mark my disks with a simple set of identification, likewise the cable on both ends, and make a sketch of ports and their sequences and which disk in which slot relates. Obviously if I was starting my system from scratch I would have done all this from the get go... but after 4 cases, various upgrades and additions, differing numbers of MB sata ports, and various sata cards and multiple variations of md's/partition layouts it all became a huge muddle and one elegant script has made it simple to finally do what I have put of for far to long. > -- > 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 > -- 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
