feature: size limit on caching filesystem

[majidaldo]

It would be nice to set a limit on the size of the caching filesystems. This would truly enable 'set and forget' kind of work instead of having to manually go into the cache location to clear things out.

I can imagine such a feature, and wouldn't be too hard to implement. You would clear old files by timestamp, oldest first. On simplecache, it would mean having to list files occasionally; on other ones to keep the metadata up to date.

Hi, is there any solution available now for limiting the cache size?

[martindurant]

I'm afraid it seems no one has had a go at this yet.

I agree that this would be very nice. I would like to add that in simple caching (so not block caching), it should also not even attempt to cache a file that is in itself larger than the cache size.
