When I try to do the remove I get .

mdadm: hot remove failed for /dev/sdao: Device or resource busy
I should also have 3 other drives that are spares . I could
try hot remove on one of them . See at bottom the output of
mdadm --misc -Q --detail /dev/md_d0
Which is showing no spare drives ? And I built it with 4
spares
Yes... /dev/sda[pqrs] are missing. I wonder why..
What does
mdadm -E /dev/sda[pqrs]
show?
See way below .
What happens if you then
mdadm /dev/md_d0 -a /dev/sda[pqrs]
??
Getting stranger & stranger .
