[ovirt-users] Slow storage migration towards nfs

2015-02-20 Thread Tobias Fiebig
Heho, I currently move some vms from fcal-store to nfs, so i can restructure the fcal storage. However, i noticed, that dd is running with oflag=direct. I/o is currently very slow (~160mbit) on the nfs-servers network. Starting dd without oflag=direct leads to link-speed transmission (~1gbit/s).

Heho, i could establish that this only happens when CustomVdsFenceOptionMapping is not set. So probably a bug. With best Regards, Tobias On Mon, 2015-02-09 at 17:24 +0100, Tobias Fiebig wrote: Heho, Currently there is four active hosts in the cluster. With the pre-existing fence

[Users] Attach NFS storage to multiple datacenter

2014-01-16 Thread Tobias Fiebig
Heho, for some reason i currently have two active datacenters in ovirt 3.3 which should be cold migrated to one new datacenter. Is there a simple way to attach an nfs-storage to all datacenters, so it can be used to migrate the virtual machines? I was sadly unable to find documentation on this

[Users] Intel Modular Server Powermanagement

2014-01-14 Thread Tobias Fiebig
Heho, we are using an intel modular server (IMS) as virtualization center in our university chair. These systems should now be migrated to ovirt. However, apparently fencing/power management via /usr/sbin/fence_intelmodular can not be configured in ovirt 3.3. Does anyone have an idea how to
