From: =?utf-8?Q?Stefan_Bauer?= To: =?utf-8?Q?linux-nfs=40vger=2Ekernel=2Eorg?= Date: Tue, 28 Jul 2015 13:17:18 +0200 Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Message-Id: Sender: linux-nfs-owner@vger.kernel.org List-ID: Hi, I'm evaluating filesystems for concurrent access(rw) from different hosts and came across cluster file systems like GFS2 and OCFS2. Is NFS in a way also able to deal with concurrent reads / writes ? I have two hosts that need to share a single storage. Access to this storage can be concurrent and to the same files at the same time. What are the limitations / advantages on NFS compared to cluster file systems? NFS looks like a simple solution for this to me. Cluster file systems require locking and fencing with addiontional components. I want to keep it as simple as possible. I would be happy to get your ideas and thoughts on this. Thank you. Kind regards, Stefan
