test: Fix sparse file self heal test
This patch solves problems caused by XFS with speculative preallocation feature on : Test EXPECT "1" has_holes $B0/${V0}0/big2bigger would fall when XFS has not freed the preallocated blocks. It is caused by XFS speculative preallocation feature. The test would pass if this feature is disabled. Speculative preallocation can speed up under linux 3.8(and later). Otherwise, the test would pass by dropping cache manually to speed up speculative preallocation. As in http://review.gluster.org/#/c/10411/, using "( cd $M0 ; umount $M0 )" to drop caches, which is better than "echo 3 > /proc/sys/vm/drop_caches". drop caches operation was added in test: tests/basic/afr/sparse-file-self-heal.t BUG: 1206461 Change-Id: Ie2c9d1b92fa8307c44498752fdd100eb86f9689c Signed-off-by: zhoushicheng <madaozhou@gmail.com> Reviewed-on: http://review.gluster.org/10253 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-by: Ravishankar N <ravishankar@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
