Extreme high load on vzmigrate

Good Morning


every time I do a vzmigrate I face system loads steadily increasing (easily going up to >100)


I did not face the same issue beforehands with proxmox. I have the gut feeling that it has something to do with my raidcontroller

03:00.0 RAID bus controller: 3ware Inc 9650SE SATA-II RAID PCIe (rev 01)

I'm running

pve-manager: 2.1-1 (pve-manager/2.1/f9b0f63a)
running kernel: 2.6.32-11-pve
proxmox-ve-2.6.32: 2.0-66
pve-kernel-2.6.32-10-pve: 2.6.32-63
pve-kernel-2.6.32-11-pve: 2.6.32-66
lvm2: 2.02.95-1pve2
clvm: 2.02.95-1pve2
corosync-pve: 1.4.3-1
openais-pve: 1.1.4-2
libqb: 0.10.1-2
redhat-cluster-pve: 3.1.8-3
resource-agents-pve: 3.9.2-3
fence-agents-pve: 3.1.7-2
pve-cluster: 1.0-26
qemu-server: 2.0-39
pve-firmware: 1.0-15
libpve-common-perl: 1.0-27
libpve-access-control: 1.0-21
libpve-storage-perl: 2.0-18
vncterm: 1.0-2
vzctl: 3.0.30-2pve5
vzprocps: 2.0.11-2
vzquota: 3.0.12-3
pve-qemu-kvm: 1.0-9
ksm-control-daemon: 1.1-1


When I do a vzmigrate pveperf shows read speeds of 0.8mbyte or similar, so it *really* goes down the drain.


This high load does not happen under normal circumstances, regular system load are around 1.5 (I have a 6core xeon so 12 threads, so a load higher than 1 should be nothing to worry about I guess)


Anyone have a clue why I have problems with this raidcontroller? Unfortunately we have this controller like 50times already since it worked flawless before
