A wiki is a repository of dynamically created and managed content, or content created or edited by multiple users collaboratively. This article is about using the wiki service in macOS Server 5.2 (the Apple Server app running on 10.12/Sierra). I reference file services with WebDAV because it is a very nice integration piece that I think a lot of people will find pretty beneficial. To get started with the Wiki service, first turn it on. This one isn’t heavily dependent on host names (other than being able to access the server from a browser) or directory services (other than being able to authenticate users, but local accounts are perfectly functional) and…

Clear Squid Proxy Caches
Every now and then you run into a problem with a caching server that causes you to need to clear out the cache. If running Squid, you can look in the /etc/squid/squid.conf configuration file and find a setting in that file called the cache_dir, which is a path.

You can clear the cache of a Squid proxy then, by deleting that directory: rm -Rf /var/squid/cache Then recreate the cache directory: mkdir /var/squid/cache Then run squid with a -z option: squid -z Then fire up squid again: squid

Dealing with Xsan Latency
In Xsan, the PIO HiPriWr shows you how latent the connection to your LUNs is. If the connection to any of your LUNs is too high then it can cause instability and worse, potential volume integrity issues. If you run into issues with this kind of latency then you should fix it. But if you can’t, then you can deal with it programatically using the Buffer Cache Size. Increasing the buffer will allow for more caching, which will in turn allow for more latent LUNs to have less effect on the overall performance, health and viability of the SAN. Additionally, the iNode Cache should be increased for the same purpose…
