I am planning to set up a 2-node RAC using VirtualBox.
We are going to use OpenFiler as the storage appliance. So, totally 3 VMs (2 RAC Nodes + 1 OpenFiler VM)
Once the LUNs are available , should we be running losetup command ?
losetup /dev/loop1 /disk1
as mentioned in Re: iscsi or SAN
Isn't partition creation using fdisk enough ?
If we use shared LUNs created from withing VirtualBox , should we be running losetup ?
There is insufficient information to provide you with an answer. You are going to need to test your proposed configuration. Hopefully this is just a proof-of-concept or test environment. You have to take leave of all rational thinking to try to use this in a production environment.
You could have probably tested it (installed/tore down/resinstalled) many times over while waiting for an answer.
Same advice I give to everyone that tries to build highly available environments on unsupported operating systems and hardware ... why?
Dropping a brick on your foot is equally painful and wastes less time.
