About the following issue, anyone could help us? Why using VM mounted by NFS V3(which is also provided by gluster) could approach full bandwidth(100MB/s),while VM mounted by gluster only reach half of bandwidth (50MB/s). The following is the mount command: 1)gluster native client: mount -t glusterfs server1:/test-volume /var/lib/nova/instance/ 2) NFS V3: mount -t nfs -o vers=3 server1:/test-volume /var/lib/nova/instance/ /var/lib/nova/instance/ is the file directory storing VMs Thanks. zhxue ------------------------------ Message: 6 Date: Mon, 14 Jan 2013 23:13:30 +0800 From: glusterzhxue <glusterzhxue at 163.com> To: gluster-users <gluster-users at gluster.org> Subject: Re: Gluster-users Digest, Vol 57, Issue 31 Message-ID: <201301142313289494315 at 163.com> Content-Type: text/plain; charset="gb2312" Thanks all the responses. It seems that I need to furtherly describe our question. If our VM is mounted on gluster via NFS(V3), writing big data on VM reach the full bandwidth. However, if VM is mounted by gluster client, it has half bandwidth when writing data on VM (mounted on gluster). Considering we don't want VM users see our gluster file system, mount gluster file on VM is not allowed. By the way, Where can I get the 3.4a version of Gluster?
