Hello, I got Error, no valid host was found while trying to provision and I could in nova-scheduler.log see that the DiskFilter failed to find a compute host. My OS is CentOS7/ running Liberty.

If I'm not mistaken, it is a bug that DiskFilter checks space available on compute-host / partition even when I'm using iSCSI and RBD backends. The / is no way near full. https://bugs.launchpad.net/nova/+bug/1358566 (https://bugs.launchpad.net/nova/+bug/...)

Can anyone confirm whether it is fine to disable DiskFilter if I'm using iSCSI and RBD backend or would anything else brake? thx will
