[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).
