What does this return?
`getconf PAGESIZE`
`4096`?
If yes, try this:
`sudo nano /boot/firmware/config.txt`
or possibly this:
`sudo nano /boot/config.txt`
and then add `kernel=kernel8.img` to the `/boot/config.txt file`. This should be added at the top of the file or in the appropriate section.
`sudo reboot`
`getconf PAGESIZE` should now return `4096` instead of `16384`

Hi Grant1
Thanks for the info it worked like a charm, I did do some research before hand and It said to change the page size, however in this day and age with misinformation etc i believe it is better to get an opinion on here, I am not an expert in Linux and just going ahead and changing stuff willy nilly is not my preferred method
Thanks Again
Stuart

Great news @acestu
Once you have data flowing into InfluxDB 3 Core, can you confirm that the [InfluxDB nodes](https://flows.nodered.org/node/node-red-contrib-influxdb) work fine? I have not looked into how InfluxDB 3 requires the fields and tags to be written (and if it differs from v2).
Thanks!

Hi Grant1,
It says in green that influxdb3 is now installed and running at port 8181, however when I put localhost:8181 into my browser it says there is a problem with the page, so still trying to get into it to create the database
Thanks
Stuart

I am not sure they have a browser-based UI in v3, acc. to [this thread](https://community.influxdata.com/t/will-core-3-provide-the-dashboard-which-like-the-oss-2/56536) from a few months ago.

Ahh right, I think I might be downloading an earlier version then, can I just ask you if I want to get rid of this version 3 do I just delete the folders or is it like windows and you have to use an uninstaller ?
Thanks

From the docs:
#### [Run the InfluxDB 3 Explorer query interface (beta)](https://docs.influxdata.com/influxdb3/core/get-started/#run-the-influxdb-3-explorer-query-interface-beta)
InfluxDB 3 Explorer (currently in beta) is the web-based query and administrative interface for InfluxDB 3. It provides visual management of databases and tokens and an easy way to query your time series data.
For more information, see the [InfluxDB 3 Explorer documentation](https://docs.influxdata.com/influxdb3/explorer/).

Without reading the install script, hard to say. A quick read suggests that it may add an additional path as well. And appears to be a local install rather than a proper install, so deleting the installed folder and removing from the users path should be sufficient.
Not sure how well developed v3 is yet. I think a lot of us still use v1. If you really want to use v3 and are already using Docker, that might be easier for now. Otherwise v1 is still perfectly usable for now.

Ah, v3 was only announced on April 15th this year. I'd be tempted to give it a while before jumping to it.

Interestingly, they offer a free version of Enterprise for home use. That might be interesting in the future.

Hi Totally,
Yes I have just been playing at home with a different setup, I have managed to get version 2 installed and collecting data from node red via the influxdb nodes, I have a little graph going but I downloaded grafina to spice it up a bit but it won't connect to the influxdb for some reason so that is tomorrow nights job, after looking at several videos on youtube they were way over the top for what I wanted, eventually I found one that was just the job.
Thanks
Stuart
