some problems with live migration

[Andrey Prokopenko]

I can't migrate VM form one node to another, RGmanager in running on both nodes.

error is
Executing HA migrate for VM 101 to node proxmoxtwo
Trying to migrate pvevm:101 to proxmoxtwo...Temporary failure; try again
TASK ERROR: command 'clusvcadm -M pvevm:101 -m proxmoxtwo' failed: exit code 250

provide more details about your cluster, e.g. post your cluster.conf

you cannot run HA with two nodes, you need at least 3 nodes, and also fencing.

see http://pve.proxmox.com/wiki/High_Availability_Cluster#System_requirements

thanks a lot. Can I organize migration whithout HA?

 

[tom]

central management and live-migration works without HA (no rgmanager!).

HA is just for automatic restart of CT/VM.

I can't start VM after migration :

TASK ERROR: volume 'local:100/base-100-disk-1.qcow2/102/vm-102-disk-1.qcow2' does not exist

looks like a linked clone. how do you live migrate VMs with local storage? cannot work.

pls tell in detail what you do now.

I did live migration , HDD image on NFS, cd image on NFS, NFS is shared , VM migrated, but can't start Syslog message is:

Seems you use SATA devices? Live migration with SATA does not work.
