[Alex, Joe, Zach]
The wiper was defining the percentage used wrong. It used "used space" over "total space", which sounds right, but due to the fact that there is some reserved space (~5% of the total), this is not the same as [ 1 - (available space)/(total space)].
The wiper, which uses the first method, reported 87%, while df (second method) reported 93% full. Since the wiper was set to keep 95% before, this means that it was actually using up more than all of the available space.
Joe couldn't find an easy way to implement the second method into the wiper script, so he settled for a different one: percentage used = used / (used + avail)
Now the wiper reports a much closer value to df.
We also changed the wiper setting to 90% for the time being, and observed that it worked properly
had been set to run as controls,
had not. Therefore, when we tried to access old data from the frames, we got
error #13: permission denied
We changed the
inittab to run as controls, so that it is matched with daqd
Everything works now
