Hi Vince for the weewx directory, your NOAA reports will disappear every time you reboot, so wouldn't weewx (very slowly) regenerate them every reboot ? I didn't notice where your archive directories are located. Do you copy the old one back into place via rc.local or something on every reboot ? We did not use NOAA reports on these raspberries. The raspberries we use only collect data and send to our servers. Archive - the weewx.db is still on the SD Card in standard path /var/lib/weewx
we run jessie on the raspberries with no problem running this fstab. Maybe /var/run to tmpfs causes problems on other systems - here no problems Does a 'systemctl' command on your system show a couple failed processes ? No :-) - frank -- Dipl. Met.

Cool. I did this in a vagrant vm and it's making systemd rather unhappy, although the system seems to run ok: initial login after bootup is 'very' slow systemctl reports user@MYUID.service failed systemctl reports systemd-update-utmp.service failed systemctl reports 'Failed to start System Logging Service' every 90 secs or so systemctl reports watchdog timeout for systemd.logind systemctl reports watchdog timeout for systemd.journald I did a little more research with some controlled reboots and found that systemd really doesn't like /var/run in tmpfs. not putting /var/run into tmpfs made the problems above go away, and 'systemctl' is clean Does a 'systemctl' command on your system show a couple failed processes ? tmpfs /var/www/weewx tmpfs defaults,nosuid,mode=0755,nodev,noatime 0 0 tmpfs /var/log/nginx tmpfs defaults,nosuid,mode=0755,nodev,noatime 0 0 for the weewx directory, your NOAA reports will disappear every time you reboot, so wouldn't weewx (very slowly) regenerate them every reboot ?

Cool idea putting that stuff in tmpfs rather than hard-allocating a ramdisk and maybe not using it...that'll give me more free space on the pi that does my weathercam.
