Hi Mauro, what would you like to store on the clustered file system ?
If you want use it for virtual machine disks I think nfs is a good
solution.
Clustered file system could be used if your virtualization nodes have
a lot of disks.
I usually I prefer use a nas or a San.
If you have a San you can use iscsi with clustered logical volumes.
Each logical volume can host a virtual machine volume and clustered
lvm can handle locks.

Hi,
We are trying to make a lab with ACS 4.16 and Linstor. As soon
as we
finish the tests we can give you some approach for the
results. Are
someone already try this technology?.
