[SOLVED] /dev/sdb1 is apparently in use by the system

[tatyrza]

Hello, I have brand new Proxmox server with subscription (latest 4.4 version). The system is on volume1 (hardware raid) as /dev/sda. Volume2 (hardware raid) /dev/sdb is empty. I want to place lvm volume on it, but I can't even format this drive. I can partition this drive in fdisk. Pvcreate returns error
"/dev/sdb1 is apparently in use by the system". Help me please!

Success! I've found the problem. It Was multipath. I had to add line
devnode "^(sd)[a-b]"
in blacklist section of multipath.conf then restart multipath daemon and thats it! Now /dev/sdb is fully available.
