    Tweaking VZDump with Ceph Backend

    I've actually read just about everything that Mr. Han has written so far. Many of his tweaks and hints are what led to the performance we can get out of ceph today. Allow me to clarify the issue further: When vzdump runs a backup of a running VM, it uses qemu directly, and through it, the...

I've seen as...

    mir, I saw this post this morning and have been testing using this option. It "appears" that vzdump ignore this when running against KVM VMs, as opposed to VZ containers like in your example. This is the new setup with 10Gbe and ceph -> 2 -> 10Gbe NFS: root@Cloud01:/etc# vzdump 1062 --remove...
