Subject: [patch] xfsqa - 008 is unreliable on 64k page size
Date: Tue, 8 Apr 2008 11:38:33 +1000 [thread overview]
Message-ID: <20080408013833.GN108924158@sgi.com> (raw)
Test 008 is unreliable on 64k page size. The I/O size is large
enough that the probability of extent merging results in intermittent
failures due to fewer extents that the +/- 10% tolerance allows.
Fix by making the files larger.
