Description

This issue was created by maloo for Andreas Dilger <[e-mail]>

This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/7cec4ac6-4f04-11e5-bc53-5254006e85c2.

The sub-test test_78 failed with the following error:

CMD: shadow-21vm3 lctl set_param ost.OSS.ost_io.nrs_policies=orr
CMD: shadow-21vm3 lctl set_param ost.OSS.*.nrs_orr_quantum=1
shadow-21vm3: error: set_param: setting ost.OSS.ost_io.nrs_orr_quantum=1: No such device
ost.OSS.ost_io.nrs_orr_quantum=1
 sanityn test_78: @@@@@@ FAIL: Expected set_param to return 0 or EAGAIN

This may relate to the recently landed patch:
http://review.whamcloud.com/15104 "LU-6673 ptlrpc: Forbid too early NRS policy tunings"

This just started on Aug 30, and all patches failing so far are based on either:
LU-6667 llite: improve ll_getname
LU-6903 lov: call lov_object_find_cbdata() inside lock
