Description
This issue was created by maloo for James Nunez <james.a.nunez@intel.com>
This issue relates to the following test suite run: http://maloo.whamcloud.com/test_sets/92e7707e-f4b3-11e2-b8a2-52540035b04c.
The sub-test test_116a failed with the following error:
test_116a returned 1
When an OST fills, test 116a looks for the OST with the minimum size available and tries to fill 25% of the remaining space, but it never checks to see if there is any space available.
This test should check if the minimum size available on an OST is zero and, if so, exit/skip.
The client test_log looks like:
