Did the setup using your scripts and my station is now live. Only one query though - how do I use GUI now? Previously lxterminal worked now I get error at boot that unable to lock .Xauthority file. -- You received this message because you are subscribed to the Google Groups "weewx-user"

Re: [weewx-user] Re: Rpi read-only SD card system usage

weewx should retrieve logger data from the last timestamp in the archive table - so as long as the data is in the logger weewx should update/reconstruct the archive database. On Sunday, 14 January 2018 08:46:32 UTC+2, Glenn McKechnie wrote: > > On 14 January 2018 at 16:13, Praveen

Re: [weewx-user] Re: Rpi read-only SD card system usage

Regarding 3 the data logger does have the data. So why can't the sql database be reconstructed? One (hopefully last!) Question. Does the script you have for rorpi setup work with stock systemd. In preinstall step if I don't replace systemd with sysV does it still work ? -- You received this

Re: [weewx-user] Re: Rpi read-only SD card system usage

Hi Praveen, 1) It will keep increasing in size as data is accumulated - the size will be dependent on archive interval and time (measured in years usually!) I wouldn't sweat on the size increasing to the point where it would be a serious problem though, or at least not before you became aware of

Re: [weewx-user] Re: Rpi read-only SD card system usage

Thanks Glen for such a detailed reply. A few more questions as i m doing my homework :) 1) The SQL database has data for how many days? 1 day? Wondering how it's size doesn't just keep increasing 2) If i do rapidfire on WU, WU would also maintain its own archive from live data i assume

Re: [weewx-user] Re: Rpi read-only SD card system usage

Hi Praveen, It's on the first page, but I agree that it probably doesn't leap out at you. You can put it anywhere you like but the default is in memory. The filesystem layout is defined around an apt install of weewx. The directory /var/lib/weewx is moved into RAM and mounted as a tmpfs with a

Re: [weewx-user] Re: Rpi read-only SD card system usage

Also Vince, your approach looks lot more simpler than Glenn's approach. But is there any downside to it? On Saturday, 13 January 2018 21:38:21 UTC+5:30, Praveen Chandrasekaran wrote: > > Again the same question as to Glenn. Where are the SQL databases stored? > Are they still on the SD card? >

Again the same question as to Glenn. Where are the SQL databases stored? Are they still on the SD card? On Saturday, 4 February 2017 05:26:34 UTC+5:30, vince wrote: > > On Friday, February 3, 2017 at 2:42:09 PM UTC-8, Glenn McKechnie wrote: >> >> The read-only pi that vince refers to is a HowTo

Hi Glenn, Where are the SQL databases stored? Are they still stored on the SD card? I could not get that reading your page or maybe I missed it. Regards, Praveen On Saturday, 4 February 2017 04:12:09 UTC+5:30, Glenn McKechnie wrote: > > The read-only pi that vince refers to is a HowTo at >

Re: [weewx-user] Re: Rpi read-only SD card system usage

The read-only pi that vince refers to is a HowTo at https://github.com/glennmckechnie/rorpi-raspberrypi/wiki/Rorpi-Home It covers installing weewx on a stock Raspian installation and then converting that to a read only configuration It's a long read, for what turns out to be a simple conversion,
