Wie wächst ein EBS mdadm raid 10 array?

Kann ich ein RAID 10-Array vergrößern? Kann ich es offline nehmen und wachsen lassen? Oder muss ich ein komplett neues Array erstellen und alle Daten darauf kopieren?

As far as I know, it’s possible, but you have to mess with the superblock. I have seen solutions that simulate RAID10 by creating multiple RAID1 arrays and use LVM to effectively RAID0 the RAID1 arrays, thus creating a hybrid RAID10. I have not tried it myself, but it seems like a good solution. It also allows you to know exactly which disks can be safely failed out, something that is difficult to discern with md.
