Create disk snapshot for VolumeSnapshot object too slowly(> 5min)

[borgerli]

What happened: We have lots of existing volume snapshots(> 15,000) in our cluster. Sometimes we created a VolumeSnapshot object , the real snapshotting operation took place after a long time, such more than 5 minutes.

What you expected to happen: no delay or very short delay How to reproduce it: This issue needs lots of snapshot objects and not easy to reproduce in test clusters. Anything else we need to know?: cause by unnecessary k8s cache resync Environment:

• Driver version:

• OS (e.g. from /etc/os-release):
