After running root.sh on node1 of the cluster you attempt to run root.sh on node 2 of the cluster and it fails stating that the disk is in use.

You check and find that reserves have been placed on the disks that were used to create the initial diskgroup which houses the spfiles, OCR and the voting disks for the cluster.

You verify that the disks are visible cluster wide and that they were created with the reserve_policy set to no reserve.
