[ovirt-users] Fw: Data Operations On Any Host

[Cryptic]

Hi Fred,


Thanks for the reply and information. When you say all testing flows were done with this option do you mean with this option disabled it is possible I could have issues that would not have been identified during the testing of this version?


Thanks.

Jeremy

Jeremy,

There is currently no option to restrict the data operations to specific hosts.

You can disable this feature in the DB, disable "DataOperationsByHSM" in the vdc_options table.

Note that since it is enabled by default since 4.1, all testing flows were done with this option.

Regards,
Fred

Hi to all,

In relation to the changes made to distribute data operations between all the hosts in a data center rather than burden the SPM. I am very new to oVirt and am having troubles finding information on this and need assistance to prevent this happening on my development oVirt 4.2 system. The issue I have is that I have a cluster which hosts all the storage volumes using gluster and they have 10G NICs. I also have a separate cluster which is virtualisation only and each host only has 3 x 1G aggregated NICs. When I perform disk moves between storage domains it often uses one of the virtualisation hosts which drastically increases the time taken to move the disk. Can I restrict these types of operations to a set of hosts or turn it off altogether so that it just uses the SPM like it used to in the past. Distributing it is a great feature but unfortunately is no good in my current setup.

Regards,
Jeremy
