Quota: fix testcases not to send parallel writes for accurate
quota enforcement Currently quota enforcer doesn't consider parallel writes and allows quota to exceed limit where there are high rate of parallel writes. Bug# 1223658 tracks the issue. This patch fixes the spurious failures by not sending parallel writes. Using O_SYNC and O_APPEND flags and block size not more that 256k (For higher block size NFS client splits the block into 256k chinks and does parallel writes) Change-Id: I297c164b030cecb87ce5b494c02b09e8b073b276 BUG: 1223798 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/10878 Tested-by: NetBSD Build System Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Tested-by: Raghavendra G <rgowdapp@redhat.com>
