Gluster users - Feb 2015 - What's the best volume type for VM

Hello?

Can anyone help me  and  give me some advice?


I have been using GlusterFS for about two years, We use Distributed Replicated
volumes to hold files as NAS, Now I want to hold some VM images (KVM/Vmware). I
am interested in Striped volume to improve IO performance.

But I found in admin guide, There are notes: "In this release,
configuration of this volume type is supported only for Map Reduce
workloads" both for Distributed Striped Replicated and Striped Replicated
volume.


Dose this mean those two kind volumes can't use for VM and other
application?



Which kind of volume is the best practise for hold VM.

Best Regards

Young

Distributed Replication is still the recommended volume type for holding 
virtual machine images.

The planned support for sharding in GlusterFS 3.7 [1] will most likely 
deprecate striping for all use cases.
