I tried to use the command as I wrote it above, but I got:
mdadm: /dev/nvme1 is not a block device.
So, not really knowing what I was doing, I added -n1 to the end of each
nvme# above and tried again. This gave me:
mdadm: chunk size defaults to 512K
mdadm: partition table exists on /dev/nvme1n1
mdadm: partition table exists on /dev/nvme1n1 but will be lost or
meaningless after creating array
mdadm: partition table exists on /dev/nvme2n1
mdadm: partition table exists on /dev/nvme2n1 but will be lost or
meaningless after creating array
mdadm: partition table exists on /dev/nvme3n1
mdadm: partition table exists on /dev/nvme3n1 but will be lost or
meaningless after creating array
mdadm: partition table exists on /dev/nvme4n1
mdadm: partition table exists on /dev/nvme4n1 but will be lost or
meaningless after creating array
Continue creating array? y
mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md1 started.
Afterwards I used GParted GUI to partition it into one partition and
format it to ext4. This resulted in 1MB unallocated space and 1.98
giggle bits of used space. GParted did not supply me with any
explanation for these, but I don't suppose it matters. Also, the device
name is no longer /dev/md1, but /dev/md1p1. And Intel advertised these
drives as 8TB, but the four of them are now 27.8 tribble bits.
Before doing all this I read up a bit on ZFS. It's probably superior to
EXT, but for now I'd rather stick to things that are more familiar.
I've spent a couple months trying to get this new storage device going,
and I don't feel like adding a new learning curve. And EXT is likely to
be around for many years still.
