I have an XCP-NG/Xen Server running with about 10 CentOS 7 (FreePBX) VM's. I want to run those VM's on my Unraid server disks so I setup a new share and made sure "NFS" was on and available on my network. I then went to Xen Server and setup a new NFS storage and right away Xen connected to the new share/storage. I started to move one VM to the new share/storage and after about 5% I got an error "VDI_COPY_FAILED(End_of_file)". Tried a few other VM's with the same error.

 

Has anyone successfully setup an Unraid server connected to an XCP-NG/Xen Server as a storage for their VM's?

I have not tried to use NFS for VDIs, but as a "Remote", which is what is a share for backups in XCP-ng.

The backup writing works, but the health checks fail in the most cases with:

Error: SR_BACKEND_FAILURE_47(, The SR is not available [opterr=[Errno 116] Stale file handle

 

I have not idea why this happens. If I remove the Remote and re-create it, the back works with health check for once. Next time when scheduled the problem re-appears.

 

If someone has a solution, please step forward.

I had used a disk share for the XO backup remote. remote encryption does NOT work with disk shares, but it does work with user shares. Time will tell whether the "stale file handle" problem also appears with user shares, more testing is required on my end.
