New Allen Telescope Array Development

Sometimes USB disks go stale after a time of non use. This was happening a lot on churn1, but also on other computers occasionally. The trick it to tell the disks not to do that. Write a little script and run it as root:

for i in /sys/bus/usb/devices/*/power/autosuspend; do echo 2 > $i; done 
for foo in /sys/bus/usb/devices/*/power/level; do echo on > $foo; done 

Restart: “sudo /etc/init.d/smbd restart”
