Raspberry Pi SD Card wear out?

[napo7]

Yes, I know that fsck repair the partition, but it's not really convenient to run a fsck at 4' AM because the server has crashed and doesn't want to startup because of corrupted FS ;)

@napo7 That is true with any server. So if you want to prevent those things from happening when there is a power failure, you put a UPS on it. Otherwise you live with the FSCK option. Simple math.

Has anyone looked at using f2fs? Support is supposedly available for Raspberry pi now. It's on my list of things to investigate, but I haven't gotten aroud to it yet.

Try using Berryboot on SD card with a USB /pen drive. It will help in SD card wear out and power out cases. I am running multiple Raspis with multi boot option on Berryboot (added advantage ) for the last 2+years. Not much of a problem till date. Lots of power outages here... No UPS support!

Do you mean to have all the operating system on the USB drive?

[vikasjee]

@gohan Yes!

BTW, I noticed dietpi already has a 460MB tempfs mounted as /tmp so I changed domoticz script to use that for log and it is working

After a failure with a cheap sd card, I've been running Domoticz for around 3 years on a Sandisk SD card with strictly no change to file system/partitions/..., I've probably had around 100 power cuts during that time (it's Vietnam...) and everything is still fine.
I think it's related to the fact that's it's a Pi 1 Model B, so it's still using SD card and not micro SD, I'll soon move to a Pi3 so it might not end up with the same experience :)

There are adapters from microsd to standard SD if you feel a little nostalgic 😁

Perhaps not the best solution but easy for a beginner.
It's possible to use "Win32 Disk Imager" to make an image of the a RPi SD card and save on e.g. Windows PC. Explained here: https://computers.tutsplus.com/articles/how-to-clone-your-raspberry-pi-sd-cards-with-windows--mac-59294
If you make an image, e.g. after changes in openHAB or at selected times, can't this be used to restore the system?
I'm aware of that data colected since the last made image will be lost and the system is down during the process.

[gohan]

Actually yes, if you make an image from a SD card and you flash it back you get a system working at that previous state. I actually use dietpi that has a built in backup/restore feature that I already used few times and it even worked to restore to another RPI also running the same dietpi
