Venus Pi Expand to Fit SD for Logging

We use the Pi in a few places, mostly pre-sales energy metering and inside pole/mast based systems for monitoring solar/battery via Ve.Direct to MPPT (and hopefully soon using @Louisvdw’s BMS driver once we switch to a supported BMS). One of the issues we are having is that the Pi does not log to disk when the Internet goes down. We’ve tried - on the older sdimg filesystems - to expand the size of the data partition, and it shows in VenusOS as having 10+ GB of free space, but still when Internet goes down, it does not log.

Any idea why?

Related, on the new wic images, when we try resize the data partition, VenusOS tells us the FS is corrupt.

I have a Venus Pi that I am using at home to connect to a BMV in my trolley backup that I have for my home office. We had an internet outage last week where the internet was down for ~12 hours, but there was no gap in the data. At our previous house I had one connected to a Carlo and pretty poor WiFi signal, but the log data will always upload once it’s restored.

I know that if you navigate to Settings > VRM online portal there is a Stored records and Oldest record age which will show how many records there are and the oldest record’s timestamp.

One thing that caught me out was that I turned on the Reboot device when no contact option, but on a reboot the entries aren’t saved, so I turned that back off.

The Pi was flashed with the Venus OS around about June last year and I think I used the rpi-sdimg.zip files, but it’s on v2.66 at the moment…

Not set to reboot. Oodles of space. But still massive gaps in the data.
