Here’s an anecdotal data point: I’ve been running with the same SD Card in the same Pi since January 2019 - almost two years. I know others have even longer working setups. I take care to save logs to a USB stick, and don’t pull power from the Pi without shutting it down properly first.
Anyway, slightly off topic I guess, but don’t be afraid to use what you’ve got already: just take care not to fill up the SD card, use a good quality SD card, don’t pull the power whilst it’s on, and regularly backup! That should be enough to get you running until ZRAM becomes an option on the 8GB version.
How about just mount log folders in tmpfs?
I did so for my Pi3 and it’s work perfect. The only note you should do as described in my post here /var/log on tmpfs - openhab2 directory issue.
Also ALWAYS use UPS for raspberry and you will not have any problems with SD cards.
No. It’s a Linux kernel issue but I doubt kernel devs are really aware of it.
Use the 64bit openHABian or restrict your mem to 4GB via kernel parameters.
Or sell your big iron on *bay, get a 4G one and sponsor the openHAB foundation with the net profit.
Wishing to start exploring OpenHAB, I read some articles in this community (on which I subscribed today) in order to determine the best hardware to start with. When searching for a Raspberry PI 4 in the, to me available online, shops I discovered that the 4 GB RAM versions are all sold out. The 8 GB version is available. While i do understand that this is a waste of memory and buck I wonder whether there is a negative effect on OpenHAB installation and running on this (too large RAM’med) platform?
