As ext4 introduced more reliability than ext3 with block journals, is there any chance to suppose it 100% reliable? What if enabling block journaling on it, which is disabled by default?
I have an embedded linux device, after installation keyboard and monitor is detached and it works standalone.
My duty is to make sure it has reliable file-system so with errors there is no way for manual correct faults on device. I can't force my customer to use a ups with each device to ensure no fault by power-failure.
what can you offer me more than enabling block journaling?
