I got two brand-new 2TB drives for a RAID1 data partition. It will hold all the stuff that I don’t want to lose. For the root partition, I’m reusing a 400G drive that I own already.
I’m downloading the most recent Arch Linux download from here. I’m using bit torrent, because big downloads are expensive for open-source projects and bit torrent doesn’t cost them. I’m writing it to a USB stick on my Mac, which apparently requires contortions like this:
# convert to the format the Mac apparently likes better: > hdiutil convert -format UDRW -o archlinux-2013.11.01-dual.img archlinux-2013.11.01-dual.iso # list current disks: > diskutil list # insert USB stick, and list them again, to see which one was added: > diskutil list # for me, it was /dev/disk6 # make sure it isn't mounted > diskutil unmountDisk /dev/disk6 > sudo dd if=archlinux-2013.11.01-dual.img.dmg of=/dev/rdisk6 bs=1m > sync # then eject
Fortunately, the BIOS of my server recognizes the USB and boots into Arch. First stop, making sure that my boot disk is working well:
> smartctl --test=long /dev/sda
That is taking a while (2hrs+), but probably worth it. Next is step 2.
