Due to the failure of a Raspberry Pi that served out the www.little-sense.au site, the sky camera will not be available until further notice.
During the early morning (00:45 local time), a red light was noticed on the local router, indicating that the connection to the Internet had been lost for at least one (1) hour. The Internet was still now at 0800 local time and a phone call to Aussie Broadband indicated that there was a major NBN fault and an SMS would be sent when the service was restored.
Service was restored at 18:30 local time.
The River Murray Trip Calculator has been removed from this site and reinstalled on the site of the River Murray Boat Owners Association (RMBOA). However, unlike on this site, the calculator is in the members-only area of the website.
It was noticed that the Raspberry Pi running the www.little-sense.au website was losing Ethernet connectivity which prevented the updating of the Skycamera images and the Ground IR Temperature captioning.
At first, it appeared that it was a hardware problem as pulling out the Ethernet cable and re-inserting it caused the Ethernet to start working for a time. This was found not to be the case when the Raspberry Pi was swapped out for another but using the same SD card. The Ethernet failures continued.
The Raspberry Pi was shifted off the local switch in case it was a cable or switch problem, but the problem continued.
Searching the Internet found that this problem had occurred on other Raspberry Pi systems and the solution was to reset the Ethernet port settings using the nmcli command to reconfigure the port.
The previous power supply used by the Raspberry Pis resulted in the Pi's annoyingly bringing up the lightning bolt on every Raspberry Pi, even though there were never any failures due to low supply voltage with these units or any other USB device powered by the power supply.
I decided to get rid of this annoyance by using an old 19V laptop power supply that is capable of providing 135W. It was connected to a series of switch mode power supplies which step the voltage down to +5.18V which allows for some voltage drop along the USB power cable.
After this power supply as tested, attached to the DIN Rail and powered up, it was found that some of the software, specifically the sky Camera did not work It was later found that the problem was the units booted at different rates and there was a race condition relating to the networked storage.
More work will be needed to ensure that the system comes up fully before the sensitive programs are started.
