Stefania commented on CASSANDRA-9686:
-------------------------------------
Yes a disk corruption due to a power cut would explain it. I don't think we
should delete corrupt sstables though, but we could maybe move them somewhere
else - where they wouldn't be automatically loaded. Then the scrub tool could
copy the fixed version back into the right folder, but this is kind of opposite
of what it does at the moment (save a backup and then fix the original).
I need someone a bit more experienced to comment on this. I'll ask on the IRC
channel.
