Hi, We have been thinking of exploiting GPU capabilities to enhance performance of glusterfs. We would like to know others thoughts on this. In EC, we have been doing CPU intensive computations to encode and decode data before writing and reading. This requires a lot of CPU cycles and we have been observing 100% CPU usage on client side. Data healing will also have the same impact as it also

It is disappointing to see the limitation being put by Nvidia on low cost GPU usage on data centers. https://www.theregister.co.uk/2018/01/03/nvidia_server_gpus/ We thought of providing an option in glusterfs by which we can control if we want to use GPU or not. So, the concern of gluster eating out GPU's which could be used by others can be addressed. --- Ashish ----- Original

After adding 3 more nodes you will have 6 nodes and 2 HD on each nodes. It depends on the way you are going to add new bricks on the existing volume 'vol" I think you should remember that in a given EC sub volume of 4+2, at any point of time 2 bricks could be down. When you make 6 * (4+2) to 12 * (4+2) you have to provide path of the bricks you want to add. Suppose you want to add 6
