Carlos, Dave:

A new nuc (build name nuc25) has been installed as nuc5 in the control room (was renamed to nuc5). The old nuc was renamed to nuc25 so I could take files off it.

I've tested the kinit script generates a kerberos nuc5 robot ticket, and the dmtviewers are able to obtain data. My new startup script expands and starts the plots correctly. The new machine had its screen saver on, I've manually turned it off. Because it has the same name, the web links to its screenshots are operational.

Reminder, we are fixing the problem whereby one of the dmtviewers segfaults after a random period of time, anywhere from 7 minutes to over a day.

We got a set of noise budget injections in while LLO was doing some commisioning, with the new PRCL FF, SRCL offset, and the curent spot positions. 

We used a reference time of  Sep 05 2019 22:31:51 UTC, we turned off the squeezer for a no squeezing reference at Sep 05 2019 23:06:57-23:17:00  UTC

We did a light set of injections, including PRCL, SRCL, MICH, intensity noise, frequency noise, IMC PZT P+Y, and CAHRD and DHARD. Results will be posted tomorow.

Jonathan, Carlos, Dave:

I've posted details in the FRS. I was able to see a segfault on one of the dmtviewers during testing this morning.

History:

Tue 3rd Sep 2019: maintenance, nuc5 upgraded from deb8 to deb9 (Carlos), launch.sh script modified to auto start dmtviewer and diaggui (Dave)

Tue 3rd Sep 2019: evening, Ed sees the FOM_STS dmtviewer crash.

Thu 5th Sep 2019: early hours, Travis sees the FOM_3-30Hz crash twice within hours

Thur 5th Sep 2019: Dave sees FOM_STS crash (segfault reported)

Carlos has been testing a dmtviewer (IFO range) on a new Nuc machine running a clean deb9 install in his office with no problems.

So, PLAN A is to upgrade nuc5 from its current old hardware with an upgraded deb9 to a new nuc with a clean deb9 install.

In the mean time, if a dmtviewer crashes, the easy way to restart it without having to reboot nuc5:

Get remote access to nuc5

    xvncviewer nuc5

Open a terminal on the Desktop, and type

    pkill dmtviewer

    pkill diaggui

    /home/controls/startup/launch.sh

FAMIS11507

No water was added to either chiller, both were near their max levels. Filters looked to be clear.

FAMIS10525

No water was added to the top or bottom. The "D" filter had some very slight darker discoloration toward the bottom of the filter, but perhaps the plastic was tricking me.

• 1st attempt:
  • ALSX was reporting "Green input alignment off"
    • Keita helped me turn on the PZT servo manually, this locked and then we switched it back to auto.
    • My attempts to get better flashes before, may have been faster than the QPD loop could keep up with.
  • 1704 lock loss from engage soft loops
• 2nd attempt:
  • Same ALSX error. This time after the ALS was shuttered we clicked the LOAD switch in the H1:ALS-X_PZT{1/2}_YAW banks, and then adjusted the bias to be closer to what the values have been. This was only done for yaw because pitch seemed to be okay. Hopefully this fixes the problem for next lock.
  • OMC sus was saturating during the Engage_Soft_Loops state, and it looked the the ASC was sending large outputs to the suspension. We waited for a bit just after that state to figure out why, but it seemed to calm itself down.
  • Observing 1750 UTC

SDFs (in attachment order):

• Top two channels are the biases that we changed, accepted.
• For some reason only PZT2 P was ON in SDF Observe, we changed this.
• This Tramp is seen after watchdog trips. It was reverted.

SHIFT SUMMARY:
LOG:

12:05 SEI Config to EQ mode for Iceland shaker

13:12 SEI Config back to WINDY

Near the beginning of my shift, I noticed that the 1-30Hz Seismic plots on NUC5 had disappeared.  Since these now auto-start/arrange on restart, I decided to just boot the machine rather than fumbling with remote desktops.  This worked . . . for a while.  Now ~2 hours into my shift, the plots have again disappeared.  Perhaps the startup script needs an update?
