Re: [ovirt-users] ovirt engine upgrade

2016-06-10 Thread Nathanaël Blanchet 
I don't advice you to do a yum update -y on your hosts if you are in 
production, because, vdsm upgrade will break your qemu process.
The best way of upgrading if you have enough ressources on the other 
hosts is to live migrate each vm from a host, so as to put it into 
maintenance.
Then, you can freely upgrade. When it's finished, activate it and do the 
same host by host.

Well the only way for you to figure out why it fails is to look at 
/var/log/vdsm/vdsm.log on the SourceHost (Host-1) and DestinationHost (Host-2) 
and see what the logs are saying, you should be finding there some ‘ERROR’ or 
at least ‘WARNING’ entries.

 Hi Anantha,
 it’s part of ovirt-guest-tools. See  
 http://lists.ovirt.org/pipermail/users/2016-May/039779.html

 There should be more details in the events at the bottom of the webadmin 
 page (just make it a bit bigger it may not be te last message)
 If they are busy VMs then you may have issues migrating them. There is 
 some simple tuning available and it may help. You can increase the maximum 
 downtime in VM properties dialog (500ms by default, you can go up to 
 whatever is feasible for your VM, seconds, tens of seconds)
 Bandwidth is limited to work on 1Gb network, if you have 10Gb availabl you 
 can also tune /etc/vdsm.conf on each host and increase the maximum 
 bandwidth 10 times
 
 Thanks,
 michal

Re: [ovirt-users] vds.dispatcher ERROR SSL in ovirt 4.0

2016-06-10 Thread Piotr Kliczewski 
Claude,

Please look for "ProtocolDetector.AcceptorImpl::(handle_accept)
Accepting connection from ". The last part of this log message
contains peername.
I should help to understand which client is connecting.

>From the message I see that the client is disconnecting and as a
result we get: 'Connection reset by peer'

Please let us know about your findings.

Thanks,
Piotr
