On a 22.04.1 Ubuntu HP EliteBook 8570w laptop the following message is displayed a number of times when I boot it without an external disk (two partitions, data not system) plugged in:
mdadm: No arrays found in config file or automatically
And in the middle of these messages, one line indicating:
mdadm: error opening /dev/md?*: No such file or directory
There's no RAID at all on this machine, and apart it takes slightly longer to boot, I see no difference when booted.
I'd like to find the way to solve this in order to accelerate a bit the boot sequence when I don't have this external drive plugged in.
I added theses lines in /etc/mdadm/dmadm.conf, followed by update-initramfs -u
ARRAY <ignore> devices=/dev/sda
ARRAY <ignore> devices=/dev/sdb
ARRAY <ignore> devices=/dev/sdc
ARRAY <ignore> devices=/dev/sdd
ARRAY <ignore> devices=/dev/sde
ARRAY <ignore> devices=/dev/sdf
And I also switched AHCI to IDE in the BIOS for no difference (regarding this topic).
Any advice?
