Re: [ovirt-users] VM Live Migration issues

2016-08-29 Thread Anantha Raghava 

Hi,

Unfortunately not. Engine log may be there, if it is not rotated 
already. But VDSM logs are not there at all.


I have two more servers of the same configuration. Let me try & simulate 
the same situation.

Hi,

The migration is working fine with Cluster Switch set to "Legacy"
Mode.

But I have run into a different problem. Yesterday, for some
reason, I had to restart the hosts. But the Hosts never came
online. Hosts were constantly in Non Responsive state. I manually
fenced it, and Vds command timed out.

I found that NIC was down for some reason. I brought it up and
again fenced the hosts. Again the Vds command timed out. I
manually attempted to restart the VDSM service, but host reported
there is no such service. Starting VDSMD service resulted in failure.

Finally, I had to forcefully remove the hosts, reinstalled base
(CentOS 7) on hosts and re-added them to oVirt with the storage
domain intact. All hosts, storage domains went online and all VMs
were intact.

Post reinstallation, I set the Cluster Switch mode to "Legacy" and
tried migration and it worked fine.

I fail to understand what went wrong while rebooting the hosts.

Re: [ovirt-users] VM Live Migration issues

2016-08-27 Thread Anantha Raghava 

Hi,

The migration is working fine with Cluster Switch set to "Legacy" Mode.

But I have run into a different problem. Yesterday, for some reason, I 
had to restart the hosts. But the Hosts never came online. Hosts were 
constantly in Non Responsive state. I manually fenced it, and Vds 
command timed out.


I found that NIC was down for some reason. I brought it up and again 
fenced the hosts. Again the Vds command timed out. I manually attempted 
to restart the VDSM service, but host reported there is no such service. 
Starting VDSMD service resulted in failure.


Finally, I had to forcefully remove the hosts, reinstalled base (CentOS 
7) on hosts and re-added them to oVirt with the storage domain intact. 
All hosts, storage domains went online and all VMs were intact.


Post reinstallation, I set the Cluster Switch mode to "Legacy" and tried 
migration and it worked fine.


I fail to understand what went wrong while rebooting the hosts.
