[LU-7105] sanityn test_28 fails with 'error() without useful message, please fix'

• Type: Bug
• Resolution: Unresolved
• Priority: Minor
• Affects Version/s: Lustre 2.8.0
• Labels: always_except easy tests
• Environment: autotest
• Severity: 3
• Bugzilla ID: 9,977
• Assignee: Fred Dilger
• Reporter: James Nunez (Inactive)

Description

sanityn test 28 was recently removed from the ALWAYS_EXCEPT list by accident and is still failing. There is no real error message, but the output from the test on failure is

'error() without useful message, please fix' 

Recently, there are many examples of this test failing and, thus, many logs of the failures. Here are just a couple:
https://testing.hpdd.intel.com/test_sets/d0ec87b2-530f-11e5-8228-5254006e85c2
https://testing.hpdd.intel.com/test_sets/7a462a70-5301-11e5-b798-5254006e85c2

From the test log output, it’s clear that this test needs to be updated; newdev was removed as an option to lctl many years ago:

Until we fix the obvious issues, we don’t really know if the original bug/reason for ALWAYS_EXCEPT test 28 is still valid.

In sanityn, the reason for putting this test on the ALWAYS_EXCEPT list is due to bz=9977.
