(Ubuntu 12.04.2, kernel 3.2.0-37-generic)

I created a RAID5 array with 22 data disks and 2 hot spares, like
this:

# mdadm --create /dev/md/dbs -l raid5 -n 22 -x 2 -c 512 -b internal
/dev/sd{b..y}

I beleive using 22 drives in a single RAID-5 is something like BASE jumping with a large umbrella. You should at least use RAID-6, and perhaps even split up the RAID into smaller ones.

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.
