Still migration problems

[Antonino89]

Hi Guys,

i'm still trying to figure out why i can't migrate CT from one server to another.

VMs migrate perfectly:

2017-08-23 11:28:53 starting migration of VM 100 to node 'Server3' (192.168.100.13)

TASK OK

But containers do not:

I also tried to check differences between CTs config files, but i can't see any significant things:

Any idea, please?

2017-08-23 11:30:29 volume 'LVM1:vm-103-disk-1' is on shared storage 'LVM1'

Any idea, please?

You marked your (local?) LVM1 storage as shared, thus Proxmox VE doesn't triggers a offline storage migration – which makes sense for storages that are really shared.
Tick of the shared flag in Datacenter -> Storage for the LVM1 one and please try again
