*Hello Everyone,*
*Good day to you !!!!*
I am currently facing an issue where a volume cannot be
attached to an instance, and I am seeing the following error logs (attached
below). I have tested this with multiple CloudStack versions from *4.20.1.0
up to 4.22.0.0*, and the same error occurs in all versions.
My environment is *vSphere 8.0.3.0* running on a *vSAN cluster*.
Could anyone please help or advise on how to resolve this issue? Thank you.
