Hi,
I created an new lvm-thin storage (connected via FC + multipath) and migrate an 20GB-Volume online to the storage.
The migration process show many times no real process (same percentages are repeaded).
First, after app. 53% the nodes freezed an only roll+capslock-Leds on the server-keybors are blinking...
(the same like here https://forum.proxmox.com/threads/node-freezed-shortly-after-update-to-kernel-4-4-8-51.27740 )

After reboot the lvm-thin was damaged!

For test I use an empty server to reproduce this with an copy of the VM - and the same behavior occour.
In this case the kernel pve-kernel-4.4.6-1-pve was running, but after reset I can reproduce the same with kernel 4.4.13 (the same freeze).

Unfortunality I need the storage and I switched back to lvm. With normal lvm I have migrate the VM twice without issue!
