Hi
Is there a way to clear the dirty data corresponding to a damaged backend?
I checked the code and found that only the dirty data that was successfully written back will be cleared of the dirty mark, but the backend has been damaged and it is no longer possible to write to the disk.
Consider a scenario where multiple backends use one SSD as a cache. If one of the backends is damaged, its dirty data cannot be cleared, which will reduce the available cache space.
