@olivierlambert our opnsense resets the TCP states so the firewall block packet because it forgot about the tcp session.

And then, a timeout occured in the middle of the export.

Hello @olivierlambert

I confirm my issue came from my Firewall so, not related to XO.

However, it could be great to make logs more "clear", i mean:

Error: read ETIMEDOUT" 

Become

Error: read ETIMEDOUT while connect to X.X.X.X:ABC

That would permit to understand more quickly my "real and weird" issue

Best regards,

Hello, @olivierlambert

Latest version,

XCP-NG 8.3 latest version, i'm trying to perform disaster recovery backup,

I think the problems seems to come from my firewall which "cut" the TCP session.

@henri9813 I found this in my logs don't know if it's related

Hello,

I have this error in xen-orchestra.

Currently, my xen orchestra is in a different network than my hypervisors.

My backup target is in another DC of course thought NFS ( via Wireguard VPN ).

Usually, it's doens't cause issue, but now, i have this error

xen-orchestra  | 2025-04-30T16:01:03.955Z xo:backups:AbstractVmRunner WARN writer step failed {
xen-orchestra  |   error: Error: read ETIMEDOUT
xen-orchestra  |       at TLSWrap.onStreamRead (node:internal/stream_base_commons:218:20)
xen-orchestra  |       at TLSWrap.callbackTrampoline (node:internal/async_hooks:130:17) {
xen-orchestra  |     errno: -110,
xen-orchestra  |     code: 'ETIMEDOUT',
xen-orchestra  |     syscall: 'read'
xen-orchestra  |   },
xen-orchestra  |   step: 'writer.transfer()',
xen-orchestra  |   writer: 'IncrementalRemoteWriter'
xen-orchestra  | }

It's problematic because, here, i think the issue is between Xen-orchestra and the final hypervisor, right ?

( it could be great to add some details on the error to ease the diagnostics )

thanks !

Thanks !

Hello,

I created some VMs using fast clone.

I also saw on forums, GitHub and documentation that It could impact on IO performance for the VM.

How could I "unlink" the VM from the template vm ?

Best regards,

Hello,

Thanks for your answer @nikade

I migrate both storage and vm.

I have 25Gb/s nic, but I have a 5Gb/s limitation at switch level.

But I found on another topic an explanation about this, this could be related to SMAPIv1.

Best regards

Hello,

So, does someone know why I can't go over 145MB/s and how to increase the vdi speed transfert ?

( I have 5Gb/s between nodes )

Thanks !

@Danp Okay, you're a genius, I upgrade this morning after my backup.

So that could explain my issue.

the mentioned thread is exactly my issue, but I didn't find it when I was searching about my issue.

Thanks for all !

@Danp i have 17 commits lates

I'm running https://github.com/vatesfr/xen-orchestra/commit/f9220cd272674ef2f0403c9b784c955783fae334 ) ( 12 July )

If it's XO related, why in xcpng I also see the blocked operation ?

Hello,

I try to migrate a VM between two host but I got:

Indeed, in can see this from xe cli:

migrate_send: VM migration is blocked during backup; pool_migrate: VM migration is blocked during backup

But ... I have no running operation

[14:19 cloud-01-rbx-002 ~]# xe task-list
[14:19 cloud-01-rbx-002 ~]# 

Do you have any idea ? ( I'm running 8.2.1 ).

Thanks !

Hello,

Could it be possible to allow show graphs in others units than MiB?

Units that could be printed:

• bit/s
• Bytes/s

however, I don't know where this should be configurable on XO

That's stupid, but i spend to much time to realize that was 2Gb/s ( I look the graph 5s and I say to myself, okay, I'm stuck at 200Mb/s, whereas .... ^^'

Best regards,
