I have the following in /etc/modprobe.d/sg.conf on Centos7:

options sg def_reserved_size=1048576

But when I run cat /proc/scsi/sg/debug it shows:
max_active_device=549 def_reserved_size=32768

How do I get these settings to take effect?

Reloading of the driver is required. Did you reboot the machine after creating the file?

I believe you can't reload the sg driver on-the-fly because the disk driver would use it already.

Rebooting did apply the new settings. Thanks! I'll submit a PR with notes in the README to help others.
