I'm getting confused, 120 mb/s is less that 20 MB/s unless you mean 120MB/s? On 16 October 2015 at 16:26, Kandalf ® wrote: > No, is real speed. From any computer linux or esxi if I write via NFS with > dd utility I have this speed. But if I try to write to one raw file like >

No, is real speed. From any computer linux or esxi if I write via NFS with dd utility I have this speed. But if I try to write to one raw file like esxi does in vmdk, than the speed drops to 20-40mb/s. So my issue is low speed when I write into raw image file (using losetup and DD on linux , or

I believe if this is replica 3 then you would expect 40 MB/s, as the client has to write to 3 bricks. You only mentioned 2 servers so I assume this is at most replica 2, so 60 MB/s would be what I would expect. This is still 1.5-3x the numbers you are reporting though. On 16 October 2015 at

Hi, I have 2 server with centos 7 and I want to make a replicate storage cluster for the esxi.In both server I have 4 disk in raid 5 mdadm. The write speed on that device is ~250-300MB/s all the time.I create xfs file system on the mdadm and I exported that gluster volume via native fuse nfs v3

I use Vsphere and I have replica 2. I share the image via gluster nfs-fuse.I have 2 dedicate LANs one to esxi and another for gluster cluster replication thats why I have 120MB/s when I create a new file onto the gluster cluster. But when I try to use that file like vmdk, the speed drops to
