How to clean (dump, remove) flash cache contents? Seems flash cache was enabled during testing phase and filled with a lot of useless data. I want to dump the content and start caching real production data.
The content on the card ages itself out and gets replaced by the new content automatically like any other cache you can see the speed it inserting new and deleting old content with the "stats show -p flexscale-access" there are metrics about invalidates and evictions per second as well as information on your hit and miss ratio
If you wanted to force it you could ether disable the cards or probably the safer option would be to do a takeove and giveback of each head. The Cache flushes and has to re-warm after a takeover and giveback.
