UPDATE: I have ordered a 8TB drive to be delivered tomorrow. My working theory is while Windows Server let me backup to the FreeNAS CIFS share, that on restoration Windows is being finicky about the CIFS and wants NTFS. I'll check that theory by formatting the 8TB drive when it arrives to NFTS and then copying the over 6TB system image from FreeNAS onto it. Plug it the drive direct into the server and attempt the restore again. Still looking for any other thoughts or confirmations.
ORIGINAL POST I have a complete system image of my Windows Server 2012 system. This image is on my FreeNAS server.
I updated my RAID 5 on my Windows Server with larger disks from a 4 x 4TB to 4 x 8TB and got caught flat with the whole over 16TB limit due to drives being made with 4K clusters and needing to be 64K clusters to expand beyond 16TB. So I made sure my backup images were good and started to restore the system image, which would then reformat the volume at the larger cluster size.
Booted up the Windows 2012 disk into repair mode and set it to restore the image. No problems getting it to see the path to the FreeNAS server. No problems with it finding the backup image.
I start the re-image and the system says it is preparing and then about 30 seconds in it says:
Restoring Disk (EFI System Partition)
Then I get the below error:
The system image restore failed. Error details: Incorrect function. (0x80070001)
I've looked up this error code and can't really find anything relevant to my issue.
And, of course, the system image ran just enough to so that I can't reboot my server.
I don't want to mess with anything further until I get some advice. I'm stuck with what to do here.
Any help/advice/idesa are appreciated!
