[LU-2899] OSTs can't be used correctly after running sanity test_27y

Tue, 12 Mar 2013 01:49:33 +0000

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
