Hi,
One of my users is preparing an exam but can't load an image because
Luwak is serving it broken (i.e. responds with HTTP 200; 0 bytes)
Visibly caused by a non-existing chunk of that file on that partition.
I would've expected read-repair to kick in and update the value. But
it keeps on serving 0 bytes.
Why is this happening and how can I fix it?
Thanks,
Francisco
