VDI_COPY_FAILED: Failed to find parent

[kagbasi-ngc]

Good-day Folks,

Today I attempted to move a VDI from one NFS SR to another NFS SR and it failed with the following error:

Is this 30d873a3-3523-1952-e923-bcaa02b9255a the UUID of the parent being referenced in the error message? If so, I can manually browse through the NFS path and see if I can find it. That said, I can confirm that both SRs are online and working, and I have completed other VDI migrations without much issue.
