If the drives support scterc, then it should be enabled to allow the drive to fail a single sector quickly without going into deep recovery mode. Run "smartctl -l scterc /dev/disk" to check if it's enabled. To enable it for drives supporting it, and allow higher timeouts for those who don't, I have the following in my /etc/rc.local to do this:
for i in {b..h}
do
dev=sd$i
smartctl -l scterc,70,70 /dev/$dev || echo 180 > /sys/block/$dev/device/timeout
done
Vennlige hilsener / Best regards
roy

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.
