Today got this error when trying to import a virtual machine on my newly rebuilt Hyper-V VM host running Windows Server 2019:
0x80070780: The file cannot be accessed by the system
I tried playing with permissions but it kept erroring out saying that it couldn't access the vhdx files. Finally, I realized that when I rebuilt the VM host, I forgot to install the data deduplication feature and thus the system could see the file names, but not access the deduplicated data.
After I enabled the data deduplication role service and rebooted, the system recognized the drives had deduplicated data and could access the files without issue.
You absolute beauty. This just saved me while trying to recover a couple of VMs from a failed S2D cluster
ReplyDeleteYou have saved me from losing 25TB of data after months of heartache and searching re 0x80070780. I could see it but couldn't use it. A simple OS upgrade caused so much grief. Date dedupe - so simple, and worked first time. Thank you so much!
