hi,
cvm offer support for raw devices(raw logical volume) and for cfs.rigt?if we have raw logical volume only,then we need to install cfs foundation as in the case that we use only cfs?
raw logical volume option is better than cfs when there is a very large I/O.right?So when is better to chose cfs over raw logical volume?beside the case that the application not support raw logical volume.
let`s say we have 2 nodes vcs with cfs on it(so parallel cluster),one instance(of the same DB) runs on node a and one instance(of the same DB) on node b.The 2 nodes share the same dg.
If node a has problem with path disks and is not able to access anymore the whole dg,what happens next?
What happens if the dg come online next?
In HA failover vcs is there a way to automatically fail back a service group,who failed over on other node?
thank so much,
marius
