Raspberry Pi SD Card wear out?
-
@gohan If you are using dietPi, you just have to run the command "dietpi-drive-manager" (sorry not sure of exact spelling, I'm not near a dietpi !)
Then, you'll have a menu that will allow you to choose per-partition read only or read-write.@dbemowsk That's a good point to avoir SD wear-out, but it didn't avoided me the corrupted ext4 partition on a power-fail.
That's why I did choose to set the root partition as RO, so I'm sure the system will not hang at startup because of "partition not clean, cannot mount it" ;)@napo7 corrupted ext4 on what? the SD card or the HDD? If it is just a corrupted sd card, all you need to do is create another one and point it to the HDD for boot and you should not loose anything. If it is an ext4 on the HDD that is corrupted from a power failure, there are ways of repairing it e.g. fsck.

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 ;)

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!

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 :) -
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. -
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
