Hi All, Can anyone give me a recommendation for a good shared-storage cluster filesystem? I am running kvm-libvirt and would like to enable live migration.
I have a number of hosts (up to 16) each with 2xTB drives. These hosts are also my compute/network/controller nodes. The three I am considering are: GlusterFS - I have the most experience with this, and it seems the easiest. CephFS/RADOS - Interesting because glance supports the rbd backend. Slightly worried because of this though "Important: Mount the CephFS filesystem on the client machine, not the cluster machine." (I wish it said why...) and "CephFS is not quite as stable as the block device and the object storage gateway." Lustre - A little hesitant now that Oracle is involved with it. If anyone has any advice, or can point out another that I should consider it would be greatly appreciated. Thanks! Sam
