Unable to mount FSx as PV from a peered VPC

[satishpasumarthi]

/kind bug

What happened?
Hi, I've been looking into getting the PV and PVC setup for pods using the FSx in a peered account. I am unable to get the FSx mounted as PV:
Currently the aws-fsx-csi-driver helps with PV and PVC setup -- It takes dnsname into account for Mounting. But we can't mount FSx (peered vpc) using dnsname, but rather IP address of FSx should be used because we can't use dnsname for FSx (From a peered vpc)
What's the recommended way to accomplish this?
What you expected to happen?
Consume FSx ip address and mount the volume
How to reproduce it (as minimally and precisely as possible)?
Try PV and PVC for static FSx volume using the dnsname. The FSx volume should be from a peered VPC.

Anything else we need to know?:

Environment: AWS EKS

• Kubernetes version (use kubectl version): 1.27
• Driver version: 1.0

specifying ip address in the place of dnsname worked. Please improve the documentation.

yea I had the same issue with DNS, just changed to the FSX -> ESI -> IP address and all worked well. you can find this IP from a simple nslookup in the same vpc.

changing to the IP address in the mount command worked perfectly

In short , use IP instead of DNS.
