@olivierlambert said in [SOLVED] XO From source restore backup fails with VDI_IO_ERROR:

So this is likely not an XO issue

Any ideas how I might manually try moving the VMs?

@chevybeef Using XCP-ng Center 8.0.1 the move also fails with: "The VDI copy action has failed"

@Danp @ronivay So here's what I tried. I moved the XO VM to another machine where I could give it more resources, 2 vCPUs and 4GB RAM. I couldn't give these resources on the main machines without over-committing. Then I tried to migrate the 24GB VM I want to backup onto the second machine but unfortunately that didn't work and it failed at 45% with "VDI_COPY_FAILED(End_of_file)". I thought perhaps it's corrupt so tried migrating another 16GB VM and that also failed with the same error. Any ideas how I might manually try moving the VMs?

@Danp @ronivay Thanks I'll try both of those things as soon as I can get passed "Job canceled to protect the VDI chain"

@ronivay, @Danp Yes, 2 different install scripts, 2 different distros and 2 different remotes, NFS and SMB, same results. They are always the same ones failing, the commonality being they are not running VMs, they are larger that the others i.e. 40GB and 16GB, and they are located on a HD not SSD, the HD also being used by another VM to capture CCTV. Transfer speed is 1Gbps, SMB share is on same HD as well.

I'm running version 8.0.0. and the latest XO running on updated version of Debian 9 with your latest version of the script (a note here is that it hadn't installed cifs-utils but even after installing that manually it didn't help). Debian is running with a single CPU and 2GB of RAM.

The host itself is a relatively low spec machine, G4600 (2c4t) with 16GB, 2 x SSDs and 1 x HD.

Issue 3242 looks interesting.

@Danp Unfortunately this didn't resolve the problem in my case. Both SMB (Windows) and NFS (FreeNAS) Delta Backups fail with VDI_IO_ERROR with "some" but "not all" VM backups. I'm using Debian 9 and the XenOrchestraInstallerUpdater script to build XO. Also tried Ubuntu 1804 with the xenorchestra_installer script with the same results, gets to 44% and then gives the VDI_IO_ERROR. Anyone know what XOA is built on, Debian, Ubuntu, other, what version?
