I have great problem with raspberry and domoticz and mysensors gateway !

[tbowmo]

@Reza

In it's default setup, domoticz writes log files and other data to the SD card all the time, and this can (over time) wear the SD card down, and eventually make it fail!

F.ex. everytime my domoticz instance receives a message from the MySensors gateway, it writes a log entry, describing which node it received the data from. (I have my log file stored on a ram disk though, so not writing directly to the SD card)

@tbowmo
now you use a external memory for log ? and have not any problem ?
can you give me a Training link for setup step by step usb memory for write log ?

[tbowmo]

No, I do not use external memory.. I have a ram disk (I take some of the RAM memory of the RPI and converts it into a "disk")

See this link for more info http://bfy.tw/Dlkf

@tbowmo you was helper for me always . thank you for this .
i found this :
https://www.domoticz.com/wiki/Setting_up_a_RAM_drive_on_Raspberry_Pi
this is help me for dont happen fail again ?
again thank you for help

[tbowmo]

@Reza

It will not totally prevent these things of happening, but it might help reduce the risk of it happening again..

[Reza]

@tbowmo thank you again my dear friend.

[gohan]

@tbowmo How big did you make the RAMdisk?

[tbowmo]

@gohan

63Mb. The sd card was made for my old 512Mb RPI B, now it runs on my 1024Mb RPI2, and have been working fine for more than a year.

@tbowmo do you know how i can stop domoticz.sh (after i compile source domoticz) for change log...
i see this topic. (https://www.domoticz.com/wiki/Moving_Log_and_Temporary_Files_To_a_RAM_Drive)
but this is for standard install. i use source and i can not how stop and change and start again....

[tbowmo]

@Reza

I think you can find information here http://bfy.tw/Dn2q

[Reza]

@tbowmo i search about this and i test this code before:
Start Domoticz
sudo service domoticz.sh start

Stop Domoticz
sudo service domoticz.sh stop

Check if Domoticz is running
sudo service domoticz.sh status

but this is dont work for domoticz that compile from source.
this is result:

pi@raspberrypi:~ $ sudo service domoticz.sh stop
Failed to stop domoticz.service: Unit domoticz.service not loaded.
pi@raspberrypi:~ $ sudo service domoticz.sh status
● domoticz.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)
pi@raspberrypi:~ $

for this i had to question from you :(

[sundberg84]

@Reza you can run ps to see current services running. Maybe its named something else when compiled from source - or its not just running? Did you try to start it before stopping it?

[gohan]

@Reza why are you running it from source and not from standard install?

[Reza]

@sundberg84

[Reza]

@gohan because i wanted change some things. for example font , theme , icons and etc...

[tbowmo]

@Reza

Once again, try this link http://bfy.tw/DnCc

(Hint.. try looking for answers by using google!)

[Reza]

@tbowmo thank you . i will search about this issue

[Reza]

@tbowmo thanks for all guide. i could do it. thank you
My friend just one question . i want know if i choose for example 20mb for ram driver (tmpfs). after full this memory (if i dont clear this), so what happen ? raspberry will be crash ? or not happen and I dont have any new log and report ? or again write on ago log ? thank you for all help

[tbowmo]

I restart domoticz every night, and delete the log file. If you don't do this regularly, the disk will fill up, and domoticz will not be able to write any logs. I don't know what will happen with domoticz in that case

[Reza]

@tbowmo
every night !! :O you do with hand or auto with a program? if you have a program for this can you share this ?
i test with 1mb memory, i see after full , domoticz dont work and have some problem. so we must clear ...
can you help me for build a program for this ? for example when this is 90% memory (tmpfs) so clear this...
