Description
This problem was found during LU-2871 auto test https://maloo.whamcloud.com/test_sessions/3d87c328-832e-11e2-98f5-52540035b04c .
In that test we have 7 OSTs, but after running sanity test_27y, only 2 OSTs were available.
This problem is easy to reproduce by adding some scripts in sanity test_27y
