Hi,
it's a bit weird, but it seems, Resolve doesn't like my stripe.
It's a direct attached external stripe (raid0) with two SSHDs.
I didn't really find a solution, but I found out the moment, the optimized media and render cache goes offline.
It's the moment, Resolve does an autosave.
Normal saving doesn't have the effect. Only autosaving.
So as a workaround, I turned off autosave.
For the moment, it works.
Thanks
Peter
