GlusterFS 3.1.5 now available

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



That was to clear page-cache on the client side, usually some of the issues
related to cache-coherency with stat-prefetch, quick-read and io-cache get
resolved temporarily.

In general this is not a good practice since the application has to
invalidate it caches proactively and keep track of them as necessary.

James, i need to know the reason behind doing it.  Was it just a hunch or is
there any specific errors you are seeing after the upgrade?
