Hello,
Is see my original post is locked...
If you want me to continue there, please unlock it.
I have only today seen your last reply there and investigated.
I upgraded first successfully to 'fvdw-sl-16.1-upgrade-patch-21dec2018.zip'.
Then I ran 'e2fsck -n /dev/sda2' (output attached).
There still were issues.
I managed to fix those issues running 'e2fsck -c /dev/sda2', see attachment (Output e2fsck -c _dev_sda2).
However, (manual) update to V17 still failed (upgrade output to v17.png) with the same error.
Do you have other suggestions?
Can I provide more logs?
I also attached the "SMART" output and the output of the short test/long test/general condition test.
