I'm trying to increase my SSD's queue depth value with the following command:
echo 64 > /sys/block/sda/device/queue_depth
But I receive the following error:
bash: echo: write error: Invalid argument
I tried using
tee and even editors like
nano but still see this error. There are 4 SSDs on this server (sd[a-d]) and this error occurs for all of them.
OS is CentOS 7 and kernel version is 3.10.0-327.18.2.el7.x86_64.
