General Issues

Handover Issues

• R4934
  • Yarragadee 12m
    • Large difference between formatter and maser delays. Check for stability of new offset. error happens occasionally and clears itself (Lim)

• AUA061
  • Yarragadee 12m
    • Very large positive data difference. +200TB or about 5%. Module is large enough to handle additional data (Lucas).

• Unordered List Item* Hobart 12m
  • a series of clock-jumps on the dbbcho on the order of -0.015us. clkoff isn't actually indicative for dbbcho problems when hooked up to Hobart12m. So don't worry about delaylive hb.

• Unordered List Item* Katherine 12m
  • Drives lost connection, got stuck. Required a thorough reboot (reboot drives didn't work), reboot system then a 2min wait+[drives on]+operate+source=disable+antenna=open+antenna=operate worked (Lucas).

• Flexbuffke got into a nasty state and wasn't happy. The first sign was the data rate on Grafana went from the 'normal' smooth 3Gbps scans to ugly, spiky and somewhat random data rates. Another sign was the number of dropped packets in “mk5=evlbi?” – maybe we should add this to katherine midob?
• The current fix is to (halt obviously), umount all the drives, remount them, restart jive5ab and re-setupsx. On flexbuffke there are two scripts in /tmp/. After logging in as su (ssh observer@flexbuffke then su in random terminal), run script /tmp/UMountAllFlexbuff.sh; wait make sure they all unmount, then run /tmp/MountAllFlexbuff.sh. After this you need to go to the flexbuffke jive5ab window (normally running on the vnc, with lots of “Reply: !”–type stuff) and ctl-C OR just pkill jive5ab from observer@flexbuffke. Then restart by up-arrowing or typing “/opt/jive5ab-2.9.0 -m2 &” or maybe …“-3.0.0” jury is out which one atm. Then setupsx in the field system and make sure the datarate is okay and “mk5=evlbi?” looks happy and is increasing (Lucas).
