To remove the storage domain, you need to detach the domain from the Data
Center sub tab of Storage Domain. Once detached, the remove and format
domain option should be available to you.
Once you detach - what is the status of the storage domain? Does it show as
Detached?

What's the output of "lsblk"? Is it consistent across all 3 nodes?
