Why does the "not large enough to join array" error occur when trying to attach a disk to an mdadm array?
When you try to connect a new blank disk to the mdadm array? there is an error "not large enough to join array", it is not clear why this happens. After all, I copied the partitions with the sfdisk command, in theory the partitions should be the same...

Disks of different models but the same size...

The section is too small. It's clearly written there.
It is possible to connect partitions of different sizes in this way only in JBOD.
You can use a disk of a different brand and size, but the sector-by-sector partitioning must match.
Make the partitioning of the disk manually using parted . You
can turn on the sector-by-sector geometry display via unit s.
For example, look at the geometry:
parted /dev/sda
#переключаем в сектора
unit s
#отображаем информацию
p
.....
#выход
quit
