I appreciate your help.That's all for now.Second thing is I was thinking about going a step forward and use NFS4 for the exports. However from what I have read about NFS4 it does locking by default and there is no way to disable them. Does that mean NFS4 is not suitable in this case at all ?Now I'm wondering about the NFS. RedHat documentation is a bit conflicting or rather unclear in some places and I found quite few manuals on the internet about similar configuration and generally some of them suggest to mount the NFS share on the clients with nolock option RH docs mention local flock and I got confused about what supposed to be where. Of course I don't know if my understanding is correct but the reason to "disable" NFS locking is because GFS2 is already doing it anyway via DLM so there is no need for NFS to do same thing what eventually mean that I will have some sort of double locking mechanism in place. So first question is where I suppose to setup locks or rather no locks and how the export should look like ?First of all I need to build a POC for the shared storage cluster which initially will contain 3 nodes in the storage cluster. This is all going to run as a VM environment on Hyper-V. Generally the idea is to share virtual VHDX across 3 nodes, put LVM and GFS2 on top of it and then share it via NFS to the clients. I have got the initial cluster built on Centos 7 using pacemaker. I generally followed RH docs to build it so I ended up with the simple GFS2 cluster and pacemaker managing fencing and floating VIP resource.Hi guys,I need some help and answers related to share GFS2 file system over NFS. I have read the RH documentation but still some things are a bit unclear to me.
