i have similar issue like this too. I'm using ext4 and it was perfectly fine when i'm using 7.6. After upgrading to ext4 and 8.2 fresh install. The CR dont work anymore.

I just tried installing Xen Orchestra from the sources on Debian 11. The same CR works well.

My previous Xen Orchestra from the sources ubuntu 18 having issue with VDI ERROR. Will do more testing.

Note: XOA is only the version distributed by Vates. Everything else is "Xen Orchestra from the sources"

@olivierlambert Thanks Corrected. I'm so happy for XCP-NG. I'm one of the early backers in Kickstarter. Hang the shirt up in our office.

Good Morning guys,

it looks like I'm having the same issue on a host that I'm doing replications. On the normal Delta Backups I'm not getting this error. But I'm getting it on the schedule Replication for only 1 of the vm's. Here is what comes on the log for that VM.

Device I/O error isn't a good sign. Check dmesg and the disk health.

rauly94

@olivierlambert sorry to ask, but where should I do this at?

AtaxyaNetwork

@rauly94 Hi !

You can type "dmesg" directly in your host.
You can check your disk's health with the command "smartctl", directly on the host too

@olivierlambert said in VDI_IO_ERROR(Device I/O errors) when you run scheduled backup:

dmesg

that's what i got. I'm I doing it correctly.

The issue is happening on 1 VM. i tried doing a copy of the same vm and same error. just FYI

@rauly94 Hello everyone.
Anyone can help me on this issue. Now it started happening on 2 vm's instead of 1 vm. It is happening on the backup replication.
