Virtual Disk Corruption Question

I have a small Microserver N40L server at home that I plan to use for mostly storage and light VM service for the house.

My Setup:

* ESXi is setup to boot from a internal thumbdrive.
* I have a OpenIndiana VM running off of a 250gig drive.
* I have two 2tb drives installed.
* Since this will not allow me to present the 2tb drives as a pass through (controller doesn't support it), I provisioned them as VMDK disks to the OpenIndiana VM
* OpenIndiana sees them and I create a ZFS Mirror with them

My Question:
So my question is around corruption. I'm not too worried about ZFS within as a file system. I'm curious though about what sort of risk am I looking at for corrupted the entire VMDK blob file? I'm concerned about not being able to mount it for whatever reason or if there is a unforeseen risk I am taking.
 
Sorry to bump but I'm curious if anyone has any experience or knowledge in this.
 
No clue, but it would be nice if you could keep us updated on how well it works. I would suggest that in your case it is a "forseen" risk 8)
 
Not sure what you mean by 'provisioned them as VMDK disks'. If you mean you created separate datastores on both drives, and then create vmdks in each datastore and presented those to the VM, there is no 'VMDK blob file', but two discrete VMDKs. I have seen people get corruption (like me) by trying to set up a physical RDM for each drive and pass them through, but it doesn't sound like you are doing that. If you are passing separate VMDKs to the VM, there is no reason inherently that you should get corruption.
 
Sorry that is what I meant by a blob file. I was trying to convey that the ZFS file system is contained inside a VMDK (one on each disk) which in my mind if the VMDK where to suffer from some sort of corruption, my fear is being unable to present that VMDK back to the VM.

Anywho...

I appreciate the input. I'll continue forward with this build (it is my home file/vm server).
