Very interesting - had not come across that - thanks
That is why it was doing nothing.

so I can "simulate" an issue now - with echo "test error" >
/sys/fs/ext4/nvme0n1p2
very correct with tune2fs -l /dev/nvme0n1p2 | grep Last
and it shows corrupt

then I reboot - and it just boots - I presume it fixed the error...
how do I simulate with an error that makes the console prompt ?
so I know for sure anything I change is indeed a fix to just repair the
filesystem.

Thanks

Jerry
