Given a RAID-5 on /dev/sd[bcde], I'd do
# mdadm --add /dev/md0 /dev/sd[fghi]
# mdadm --grow --level=6 --raid-devices=8
No need to create a new RAID and then move the data.
Vennlige hilsener / Best regards

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med xenotyp etymologi. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
