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

[Reza]

@sundberg84
i buy a new sd card and write again os and domoticz and gateway...
now LED is ok and i have a ip for raspberry. but i think my raspberry's hardware is failure because now my commands send with a lot delay or can not send. or save and send all commands together suddenly . Do you know why?

but about read only. thank you . i read this. but i have question. with this work after power off/on my sd card will not fail , is this true ? but when i do to read only , there is not any problem in Performance domoticz and my sensors and gateway? for send and receive commands ?after setup domoticz and my sensors gate way i can change to read only ? thank you

[sundberg84]

@Reza -I dont use read only because I wish to log. Instead I backup my database every day... preparing for a SD-card failure.

I have bought a class 10 8gb SanDisk and this has lasted me 2 years now with standard settings. First one was about 6-8 months with another brand.

Use Berryboot AND fast USB drive to solve most of the problems related to corruption on SD card due power failures and number of write cycles. I have been using it for 2+ yrs now...

@sundberg84 my new sd card is sandisk. setup again domoticz and mysensors gateway...
now os is ok even with power off/on. but i think my raspberry is fail . i think cpu is fail. before i compile domoticz with -j4 without any problem . but now with -j4 after 10-20% rpi is freeze. even when i compile with just make, when i want use domoticz for send command for relay , this have a a lot delay , or command can not send , or save command and after 1 min send all command. i think cpu can not work correct and have a hardware problem ! but i dont know why happen this ! after 7 month rpi was on the table and power was ok and i dont install any new software on the rpi ! suddenly happen...

[Reza]

@vikasjee thank you . but my main problem is not sd card . after 8 month my Rpi is fail suddenly :( i want found why...

@Reza

Continuous writes to a SD card, will make it fail at some point in time, it's just a question of time!.. And thus it will make the rpi fail.
Another thing can also be powering issues. (and even combined with a failing SD Card..)

[Reza]

thank you dear @tbowmo
so this (fail cpu or rpi board) can related to write in cd card ? because i am confused .i can not found why suddenly... . i tested power and didn't have problem(if power of my house have problem so first power supply of raspberry should to fail). my rpi was working for 7-8 month without any access people to it and i dont any install new app or program. just power on rpi and put on my table !
in rpi was just domoticz and mysensors gateway. i used this just for smart home.
now i want just found reason of problem and solve this :(
do you think this problem (rpi fail) can related to sd card ? (According to the above description)
if yes , so for resolve , what is your suggest ? use a usb memory ? or read only (i want use rpi just for domoticz and mysensors gateway and devices)?with read only i can not see any report in domoticz log ?
thank you

@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)

[Reza]

@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")

@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.

[Reza]

@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?
