Steve noticed the RGA was not working today. It was powered on but no other lights were lit.
Turns out the c0rga machine had not been rebooted when the file system on linux1 was moved to the raid array, and thus no longer had a valid mount to /cvs/cds/. Thus, the scripts that were run as a cron could not be called.
We rebooted c0rga, and then ran ./RGAset.py to reset all the RGA settings, which had been reset when the RGA had lost power (and thus was the reason for only the power light being lit).
Everything seems to be working now. I'll be adding c0rga to the list of computers to reboot in the wiki.
