the correct way to do a bulk migration is either via the webinterface or

pvenode migrateall

see man pvenode for details and options

i use web bulk migrate,after migrate successful, vm is lock,i don't know what happen,so i use command "qm migrate",lock too;
 
can you post the task log of the migration from the locked vm ?
 
no i meant the task log

each migration has a task log in the webinterface, when you double click on it , you should see some the migration output

maybe the node where you want to migrate to is not in the ha group for this vm ?
 
I test 15 vm migrate，in active-backup mode network ，about 10 vm were lock，another，about 5 vm were lock
 
it sounds like your cluster network is overloaded, what does pvecm status ha-manager status say?
how does your network setup look like?

maybe you can try to reduce the ha workers (see man datacenter.cfg for that)

i think /etc/pve/datacenter.cfg maybe unuseful,i echo 'bwlimit: migration=142' in it ,but speed also more than 200M/s
 
Hey guys,

I am encountering the same error with a much up-2-date version of pve.

Environment details:
  • 7 prox nodes running the same version
  • each prox node connects via dual 10 Gbit NIC with 2 switches and forms an MLAG Po
  • each traffic type (also cluster -corosync vlan) separated/designated on each vlan
  • use of openvswitch 2.7.0-3 with balance-tcp and lacp rate set to fast

Note: the hagroup is created to have all nodes included, restricted is unchecked and nofailback is checked.

The VM migration is done via the GUI using bulk migrate action, selecting the specific instance IDs and settings 2+ parallel migration jobs.
I am under the impression that running more bulk migrations on the same time for ha-managed vm id cause the vms to enter stall state, somehow like the VM get's on the node and the config is left behind :)

Let me know if I can provide you with more information.

Thanks,
Alex
 
I have a cluster with a large amount of VM's and I also hit issues on large bulk migrates were some VM's end up in a "freeze" state and stay that way until I hit resume. Running a dedicated 10G backend network as well, only traffic on it is the cluster.
