Re: [Xen-users] XCP and Gluster


I would really recommend against using Gluster or any filesystem based
method of providing VM storage, you are much better off using a block
based storage system. iSCSI is many times more efficent and fault
tolerant than Gluster.
My recommendation is to use the FUSE driver within the VMs to connect
to Gluster volumes if you require them.
