Master node migration failed with on 'lvcreate os -n root -L 9,77g'

[Egor Kotko]

Baremetal. Master node migration failed with on 'lvcreate os -n root -L 9,77g'

Steps to reproduce:
1. Deploy environment 3Controllers, 2Computes
2. Migrate master node on one of the Compute nodes:
#fuel-migrate <ip_of_compute_node>

Actual result:
failed with error message:

Warning: Permanently added '172.16.39.131' (ECDSA) to the list of known hosts.
Create VM fuel_master on 172.16.39.131

But if go on created VM and create lv volume with different size it will pass:

root@bootstrap:~# lvcreate os -n root -L 8g
Logical volume "root" created
