<div class="moz-cite-prefix">Hi all,<br>
<br>
It's been a while and I have been doing tests in the background.<br>
<br>
I found some issues were related to faulty drives, but after
removing them migration issues continued. I had the same issues
with PVE 3.2, nfs, rbd and local storage.<br>
<br>
I also noticed that out office production cluster doesn't seem to
suffer this problem (PVE 3.3) .<br>
<br>
Today I found this post on the forum:<br>
<a class="moz-txt-link-freetext" href="http://forum.proxmox.com/threads/19733-storage-migration-virtio-failed">http://forum.proxmox.com/threads/19733-storage-migration-virtio-failed</a><br>
<br>
Short is that in /usr/share/perl5/PVE/QemuServer.pm<br>
changing:<br>
---<br>
<pre class="bbcode_code" style="height:84px;"> if ($vmiddst == $vmid) {
# switch the disk if source and destination are on the same guest
vm_mon_cmd($vmid, "block-job-complete", device => "drive-$drive");
}
---
</pre>
with<br>
---<br>
<pre class="bbcode_code" style="height:84px;"> if ($vmiddst == $vmid) {
sleep 10;
# switch the disk if source and destination are on the same guest
vm_mon_cmd($vmid, "block-job-complete", device => "drive-$drive");
}
---
</pre>
<br>
So adding a sleep, seems to have fixed all the migration problems
so far (I continue testing while I write this email).<br>
<br>
The problem seems related to performance. The problem-suffering
cluster has 3 nodes each with 1 desktop CPU, 2 GB RAM, 2
relatively old hard disks (~60MB/s write on NFS). Network is
1x1Gbit on each node, all on the same HP 1gbit switch.<br>
<br>
Although a work-around, maybe putting a sleep 1 could help some
users while not being noticeable for the rest?<br>
<br>
Cheers<br>
Eneko<br>

Does anyone with PVE 3.3 have working online storage migration

Yes doing it with VM off works, but I can't make
it work with VMs on. It used to work in 3.2 and
before, something must be broken.

I tried local to RBD storage migration

does with NFS:<br>

I noticed that during migration HTML5

work (VM doesn't receive keys).<br>

Is storage migration working for you
in PVE 3.3?<br>
