i have a corrupt btrfs in which my / resides. I can't mount it anymore. System does not boot, it resides in a very limited shell. This is my first corrupt linux filesystem, i was lucky all the years doing system administration :-)) So i'm a bit nervous and don't know exactly what to do. Who has experience with corrupt btrfs ? Shall i try to repair with the SLES installation cd or prefer a knoppix ? Or from this limited shell ?

Thanks for any tip.
