Weiß jemand, wie ich damit umgehe. Muss ich bei einem bestehendem Dateisystem Änderungen/ Anpassungen vornehmen? Reicht es die Option im kernel einzubinden? Ist das ausgreift oder kann ich mein Filesystem schrotten?

Mounting with the option journal_checksum should be sufficient. I use it since ages. I had some problems with the filesystem, but I doubt that this option was related. Of course, nobodoy can say for sure...

edit:

na prima - da hab ich doch glatt journal mit metadata verwurstelt 8O


das letzte Mal, als ich über metadata checksums und ext4 gelesen hatte, war noch davon die Rede, dass e2fsprogs das vernünftig unterstützen müssen

ist das mittlerweile der Fall ?
