I am poking through dmesg to pinpoint a problem and I found this
dmesg | grep -i raid

So I did some investigating and I have "mdadm" installed
/etc/mdadm.conf
/proc/mdstat
But I don't have all files mentioned in man mdadm.
I haven't installed raid per-se but is it a partial install by default
It may be the result of your hard drive or SSD being listed as a RAID
device in the UEFI or BIOS. The kernel might detect that and load the
RAID module.
If you really had a RAID-6 configuration, you'd know about it,
wouldn't you? RAID-6 doesn't exactly set itself up automatically. ;)

lvm install, they are needed. They do no harm if not actually being used other
a few messages in the journal.

My suspicions were in that orientation but it's nice get confirmation

My 2 inch solid-state drive that has never been detected by any OS still makes RAID try about 4 times to load it, so RAID must see it as a drive.
I have always associated RAID with multiple drive scenarios, but this thread suggests that RAID is of more general application. What exactly
is it?
