How to create Oracle RAC with Proxmox?

[ksun]

Greetings,
I am new to Proxmox world. I believe oracle RAC is a good place to evaluate the capabilities of Proxmox.
In particular I like to set up shared storage accessible in parallel by two or more VMs to eventually create ASM inside RAC.
The cluster file system that I read is for small configuration file and is apparently not for ASM.
Is there any video or tutorial that demonstrates the creation of Oracle RAC?
Thank you!

That depends on the backend storage type. If you use iSCSI, there is no problem installing the clusterware and everything is as it would be on real hardware. If you don't have iSCSI, the easiest method is to run a additional iSCSI portal as backend storage for your cluster.

Keep in mind that PVE or more precisely KVM is not a supported environment for Oracle software (as is VMware and everything besides Oracle VM). If you run into a problem, Oracle support can say that you're running in an unsupported configuration and that you replicate your problem on hardware. I've never seen this, but it is a noteworthy potential risk. Licensing can also be a problem (or just darn expensive), please consolidate with the Oracle LMS before running into licensing issues.

Thank you for the suggestion and warning.
I have not tried inode yet.
Is any other disk type support "concurrent access"?
In VMWare term, the disk mode should be shared and independent-consistent.
Any equivalent disk type/mode in Proxmox world?
Thanks!

Rather than retyping, I'll just use the link to point to the other thread with the same question:

This way those who come across this thread and not the other can find the reference.

I would suggest the use of CephFS if the OS of the VM's has a client for it. Think of it as a highly available, replicated and redundant "NFS". You could create a Ceph cluster with Proxmox, provision some CephFS and give permisions to your VMs to use CephFS. It does work quite well for me as a shared storage for web apps and file servers, albeit it may not be performant enough for your workload.
