Description
Fixed the issue where a Bound PVC could get stuck in the cache due to the LVGCacheWatcher executing earlier than the PVCCacheWatcher, causing the PVC to be updated to status Bound after the clearing operation.
Now, there is a special algorithm that monitors for expired and Bound PVCs in the cache and removes them. Users can specify the desired expiration time through the sds-local-volume-scheduler configuration.
Why do we need it, and what problem does it solve?
Due to this bug, some Pods might not have been scheduled correctly due to inaccurate node free space counting.
What is the expected result?
No freezed PVC in the cache, everything works fine.
