[Opensim-users] What is the best way to manage asset cache on an OSgrid set of regions

[AJLDuarte]

Hi,
	A) yes it is good idea to share assets cache
	B and C)
	Cache will grow for ever taking 2 much disk space possible with useless entries.
	Using one instance to do expires is a option, it will even try to not delete assets in use, but just on that instance, so not that useful in this case, just waste of cpu.
	Using a external tool (both windows cmd and bash have usable commands) to delete files modified long ago is another option.
	Wrong deletes should not be a major issue, assuming all assets are on grid databases, if not you are in trouble anyways :)

Ubit

Subject: [Opensim-users] What is the best way to manage asset cache on an OSgrid set of regions

I run three servers each have a few instances of opensim running on them and all of the regions are on OSgrid.

I have a common asset cache  for each servers, that all the instances use.  Maybe that is not a good idea, but I thought it might help keep it’s size smaller than every instance having it’s own asset cache.

Up to now I have not expired any items in the cache.  Yes, they are massive in size.

I have been thinking about having one instance expire the cache and using a retention time of 48 hours.

Is that a good or bad idea?

I do have a fair amount of activity on each server as I run free home sites for many OSgrid users.

I am wondering a few things:

- Is running a single cache for several instances of opensim a good or bad idea?
- Is not expiring the cache a good or bad idea?
- Can one instance do the expiring of the cache for all instances since they all share the same cache?
