| On Save/Restore Module Settings Tab - "inquire save state" returns an error. See attachment 1. |
|
Wed Apr 3 13:29:20 2019, CA, CB, TD, report - high DAQ stall
|
aida10 runs very fast for a period, then stops.
Have to restart Merger and TapeServer to get it running again.

Quick system checks after crash
Temperature ok.
Still cannot connect remotely to /ucesb with my gsi web login and password (?). |

Tue Jul 7 08:50:27 2020, NH, nnrpi2 does not boot
|
MIDAS was not working properly on nnrpi2 - power cycled. Now system does not boot properly, it gets stuck trying to login claiming "PAM critical error"
- probable file system corruption?
Will investigate if SD card can be checked and repaired |
|
Fri Apr 9 16:40:36 2021, NH, nnrpi1 Update
|
nnrpi1 is now back in S4 with a new SD card and new raspberry pi.
The freezing originally continued (it was the USB system failing) but was fixed with a change to /boot/cmdline.txt coherent_pool=4M
It seems the kernel update to fix one bug introduced another...
|
|
Tue Mar 30 13:21:50 2021, NH, nnrpi1 (tty logs)
|
We had issues with all TTYs reading out on nnrpi1, I have moved them from an apparently faulty USB hub to a new one.
Trying to reboot the pi to detect the new USB ports and it didn't recover from boot
Trying to repair SD card but I get a lot of errors on my laptop, indications are the SD card is completely dead
|
|
Tue Oct 6 15:48:06 2020, NH, nnrpi kernel update
|
FYI:
The SD card on nnrpi2 was full again causing issues, the log files in /var/log (kern.log & messages) were *huge* and filled with the same error many times |
|
Sun Jun 26 23:04:30 2022, Marc, new shift - Monday 27 June 0:00 to 8:00 12x
|
0:00 Experiment continues to run smoothly. AIDA DAQ has been rather stable. Leakage current has gone up for the past two days in both DSSDs (combination
of high-Z and high-intensity beam and external high temperature).
Stats & Temperatures (VIRTEX,PSU, ASICs) all ok. |
|
Fri May 13 02:28:36 2022, ML, beam dropped
|
We see less counts in AIDA implant DSSD1 (~1Hz) than at the beginning of the night shift (~10Hz).
This seems to be beam related as the count rates in DESPEC & FRS Scalers seems to have dropped too. |
