Adding note information for SD card use on Zabbix Requirments pages

[CorentinL]

Hello,

Firstly I tried to install zabbix on a Rock 5b first,in a second time on a Raspberry and get the same result for both installations on a SD card, the SD card get stuck with no access to the little computer(see the screenshot below). I think it may be a good idea if a note could be write for this behavior in Zabbix Requirments Page. According to some sources this behavior is due to the read/write approximatively permanently on the database and the advice I found is to installed zabbix in a separated USB drive/M.2 disk.

Thank for your reading

It's a pity you had to learn it the hard way, but it is not Zabbix fault as it has a lot to do with common sense imho. Many products use a sql instances as a backbone but they almost never mention not to use a sd card driven device as it is considered, again, common sense.What does help is the fact that you created this post mentioning the issue so others will hopefully see your post before installing Zabbix (and especially sql) on a sd card. So in short, thanks for mentioning it

I agree with you in the fact that many products use a sql instances but for compatible product with arm architecture such as Raspberry, the only way to install it is on a SD card. Furthermore, Zabbix software is perfect for lightweight computer which for the majority have only a SD card slot.

I agree with you that the Zabbix server can be lightweighted, but it still does depend on a database. And databases are a no go on sd cards.You can stick your head in the sand and ignore it but the truth is databases tend to be disk i/o hungry. Now that you mention the Raspberry, you can use and build a setup using a nvm on your pi. You can use this advice or just ignore it and destroy an other sd card.
