2015-03-17 Today, I switched the home server disks back to UUIDs. This worked fine. I think it worked now because I did it from the run- ning system itself and not from some other system by chrooting. I also did an `update-initramfs -u'. I haven't cared for that be- fore and still don't really understand it, but it might help. When I plugged the second new 3 TB drive in, I had to connect them into the right order to the SATA controller, because that seems to try to boot them in that order. If the bootable disk was second, it just stopped with ``no bootable device found''. To partition further disks for a RAID1, I used to use sfdisk(8), but that cannot handle GPT. Hence, I used parted. for exact par- tition boundaries, I changed its output with `unit s' to sector units. Then I copied the numbers manually. I created the two RAIDs (system and data) on the new disk with always the first member missing. The system disk is still open to be moved onto the RAID, but the (empty) data disk is already syncing. Creating the ext4 filesystem for the nearly 3 TB large data partition took about five minutes, I'd say, maybe ten, but not more. The mdadm sync will take a lot longer. It syncs with about 57M/s, which is fast, but it'll still take about 15 hours! The (missing) noise of the new disks is really impressing me. This old 10 GB disk was truly loud. I heard it even through the wall. These new disks are hardly audible, even if both are seek- ing at that time. I would never not have imagined that differ- ence. It is, at the same time, a bit depressing, because it means, that old hard disks are losing the rest of their worth. Their only remaining use case are old mainboards that cannot han- dle newer disks. But of what use are old main boards anyway? This is realization is hard for me. First, the hardware was too rare and expensive, now it is available and still fast enough for me (!), but at the same time, it's not worthwhile to run them anymore. New Hardware is cheap enough and available and consumes less power and is less noisy. And eventually, one starts to run only one single hardware machine and runs all the others virtual- ly. Gone is the aspiration that one day, we software guys would have an increasing haptic experience. The contrary is the case: All parts of our work become more virtual ... Oh, I'd really wish to have a hardcopy terminal! http://marmaro.de/lue/ markus schnalke
