QNAP – Raid Expand SLOW


When you change RAID configuration in a QNAP you might have sometime slowness during the Expand of the disk.

To improve the speed, log in the QNAP in SSH (Enable it first if disable).

ssh admin@your_ip

Type the command : echo 25000 > /proc/sys/dev/raid/speed_limit_min

You do not need to reboot or restart the Expand. This value will be taken on the Fly.
