It's not clear what happens.

fuel-agent log stops at

any 'lvs'/'pvs'/another lvm related command gets stuck.

[root@bootstrap ~]# pvs

Also noticed that if 'provision' is executed in background just as 'provision &' it will fihish proreply.

I'm not sure how to properly reproduce lvm deadlock and how to avoid it.
