Re: [ovirt-users] How to disconnect hosted-engine NFS storage pool?
Hello Ryan and Doron, Indeed a useful feature, I ran into this issue but forgot to mail. I think in reality it is already best practice to put hosted engine on its own NFS share (iSCSI LUN, Gluster-Vol in the future). Should we make this an requirement?

The ideal is to have it as every other VM, so I'd rather not add requirements. Hello Doron, makes absolutely sense (at least for developers who need to test things a lot ;) From a practical point of view though it will always a bit different as long as you do not plan major design changes with hosted-engine because of the potential lockout problem (engine-ha and shutdown / reboot, IIRC right now no management other then migration from within ovirt). I know you will have engine more 'manageable' form oVirt itself in the future, but for the following reasons this is not very important for me: Since in a worst case scenario engine is crustal getting tings working again, 'users' (at least me) would tend to use a much simpler/robust setup for engine storage (for instance, plain nfs, gluster 'local' cluster - one replicated brick per host, no dm-multipath ect.). As for the storage of 'production' VMs other points tend to be more crucial (performance, multiple pathes, easy provision and administration ...). My point being, common sense suggests you setup engine storage different from 'production' storage.
