I have done the following:

ssh'd into the hws computers (h1hwsmsr, h1hwsmsr1, h1hwsex, h1hwsey),
opened tmux sessions (tmux attach)
found seg fault, screenshot in first attachment
I ran the thinning script (thin)
- even after running the thinning script it seems like we're filling up these computers faster than we can keep up with (compare second attachment with the capacity after TJ deleted a bunch of stuff last wednesday).
and just restarted Hartmann code (python run_HWS.py -c {0/1} where IY EX and EY are 0, and IX is 1)

I'm not sure if this was the right thing to do; let's see if this keeps it alive during today's CO2 test.

I ran the thinning scripts for all 4 camera directories. ITMY seemed to remove the most by far. We are now at 82% capacity on /data

I am in the process of making a script to automate the thinning and checking that the files were backed up, but until then we will need to keep an eye on this.
