Message-ID: <20100426225627.GA7106@esri.com> MIME-Version: 1.0 Content-Disposition: inline List-Id: XFS Filesystem from SGI List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: xfs-bounces@oss.sgi.com Errors-To: xfs-bounces@oss.sgi.com To: xfs@oss.sgi.com End-user question: NFS client accessing an NFS export on an XFS based filesystem via "sync" (O_SYNC) mode. Will write confirmation be sent back from the NFS server when the data is written to the xfs journal, or not until it is actually written to disk (assuming in this case the journal is on a separate SSD device or something similar)?
