Content Caching

[awginger]

Hi all, we have content caching enabled on Mac minis in schools, however keep getting an issue where software updates can't install as there is not enough free disk space.

When this happens I try to run AssetCacheManagerUtil flushCache from a policy to clear the cache and make some room but I get the following error from that command:

2020-10-12 12:01:28.762 AssetCacheManagerUtil[59888:582539] Content caching did not flush its cache: Error Domain=ACSMErrorDomain Code=9 "required by your system administrator" UserInfo={NSLocalizedDescription=required by your system administrator}

Should probably point I have no access to these Macs other than with Jamf so looking for idea on how I can do it, without just reducing the amount of disk space I allow for cached content.

Reset the cache and then set the amount of space that can be used for cache. This is the script I used to reset the cache.

#!/bin/bash
serveradmin stop caching
sleep 5
rm -rf /Library/Server/Caching/Data/
sleep 30
serveradmin start caching
serveradmin settings caching:CacheLimit = 450000000000

Hi @ChrisTech , Thanks for this!

We are currently turning on, and configuring, Content Caching with a config profile - will trying to change the settings via this script, I am particularly thinking he limit piece, not get 'trumped' by the setting in the config profile?

@ChrisTech Your script won't work on Mojave+ since Server.app (and therefore serveradmin) does not contain Content Caching anymore. And since the OP is using a profile to configure, that means he's on Mojave+.

@patgmac We are indeed on Mojave+, Catalina in fact
