Yes, now I install the 2 new Slackware machines and I want to setup gluster + iscsi. I hope that will work as I expected. Do you know to be some issues if I use multipath to the both gluster servers from esxi?

 From memory, nfs doesn't play very well with vSphere. Are you able to try iSCSI over gluster?

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 ~20-40MB/s.

But if I try to mount an raw file image with losetup, or use vmdk files, and if I write to them, the speed is 20-40MB/s and I see 12 load on linux.

What VM hosting are you using? KVM/Qemu? vSphere?

How is the image shared out? gfapi? nfs?
