Description

https://testing.hpdd.intel.com/test_sessions/93d0b46a-0a02-11e7-9053-5254006e85c2

In test_log, I'm seeing the following error:

error: set_param: setting /sys/fs/lustre/ldlm/namespaces/lustre-OST0000-osc-ffff880051347000/lru_size=clear: Invalid argument

This is followed shortly afterwards with a test failure:

CMD: onyx-32vm4 /usr/sbin/lctl set_param -n obdfilter.lustre-OST0000.lfsck_verify_pfid 1
fail_loc=0x1619

The set_param failure above may also cause this:
