Node x.x.com holds the SCSI PR on Test Disk 4 and brought the disk online, but failed in its attempt to write file data to partition table entry 1. The disk structure is corrupted and unreadable

i have the following windows 2012 r2 setup:

Hv1 - hyper-v installed with failover clustering on SAS- hosting virtual DC on SAN

hv2 - Hyper-v installed with FC + DC on sas

hv3 Hyper v + FC on SAS

When running the failover clustering wizard i get the following on each node:

"Node x.x.com holds the SCSI PR on Test Disk 4 and brought the disk online, but failed in its attempt to write file data to partition table entry 1. The disk structure is corrupted and unreadable."
