From: javocado To: freebsd-fs@freebsd.org Content-Type: text/plain; charset=ISO-8859-1 X-Content-Filtered-By: Mailman/MimeDel 2.1.14 X-BeenThere: freebsd-fs@freebsd.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: Filesystems List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 16 Jul 2013 20:26:10 -0000 I have a couple questions: - what does it look like when zfs needs more physical memory / is running out of memory for its operations? - what diagnostic numbers (vmstat, etc.) should I watch for that? swapinfo shows zero (basically zero) swap usage, so it doesn't look like things get that bad. Thanks
