cdslogin alarms and alert system not working since 4am Sun 01 Dec 2024

cdslogin is in a strange state, not quite down but not sending alarms or alerts. It is pingable, I am still using it as a ssh-tunnel for my no-machine connection to opslogin0, but it does not accept any new ssh logins and my shell on it cannot find any commands.

File system error starting at 03:42:20 this morning

I power cycled cdslogin remotely via IPMI (10:50 power down, 10:52 power up) to force a fsck. The system came back up in operational mode, the systemd services alarms and locklossalerts started normally.

These services write to the local file system, which is presumably why they were down when the local FS switched to read-only mode.

Two improvements spring to mind:

Make alarms and alerts memory resident only, no reliance on any file system.

Make these services portable to cdsssh if cdslogin became unusable.

There is no indication of any mains power issues at 03:42 this morning. No UPS reports, and the three phases of the corner station mains-mon look good throughout.

H1 Calibration Measurement For Mon Commissioning (broadband headless + non-standard simulines)

H1 will be thermalized right around the Sat Calibration time of 1930utc (1130am PDT).  L1 has been down due to a frontend crash/chassis swap this morning, so will jump on this down time to get the calibration run for H1.  Louis Dartez wanted operators to continue running the new/non-standard simulines measurement (noted below).

Sat DAY Ops Transition

TITLE: 11/30 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Earthquake
OUTGOING OPERATOR: Ibrahim
CURRENT ENVIRONMENT:
    SEI_ENV state: EARTHQUAKE
    Wind: 6mph Gusts, 4mph 3min avg
    Primary useism: 0.10 μm/s
    Secondary useism: 0.25 μm/s
QUICK SUMMARY:

H1 lost lock recently most likely due to a M5.4 earthquake off the western coast of Mexico.

Overnight H1 had a lockloss at 1245 with no IMC/FSS oscillation tags.

It is Saturday, so a Calibration is scheduled late morning, but thermalization requirements may push this out to the afternoon since H1, L1 are currently both DOWN and V1 has been Observing 15min.

Fri Ops DAY Shift Summary

TITLE: 11/29 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 160Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:

About 100min of downtime for the 9hr shift (with a lockloss early in the shift and one near the end of the shift).  For speed, I nudged H1 to CHECK MICH FRINGES to help with DRMI (the 2nd lockloss' ALS locking was all automatic).

Chilly Black Friday with temperatures barely going over 35°F.  µseism looks like it might have slightly inched above the 50th percentile over the last 24hrts.

23:49 UTC lockloss (5:32 lock)

23:49 UTC lockloss IMC tag, ASC and IMC lost it within 5ms of eachother. It looks like the ISS might have lost it first then 30ms later the FSS and ASC lost it.
