Description
Most smartctl commands have a default timeout of 20 seconds. This is sufficiently long for pretty much any disk to spin up from standby. However, many large JBODs implement staggered spinup, where they limit the number of drives that can simultaneously spin up. On such systems, it may take considerably longer for all drives to spin up. For example, I have a 96-drive JBOD where spinning up all drives takes nearly 45 seconds. The attached patch fixes smartctl for me.

I think it is fine. Moreover, in some code controller-specific this value is not respected and 60s is hardcoded. I will commit it
