glusterfs.git/tests/basic/afr/durability-off.t, branch v8.1 cluster/afr: Delay post-op for fsync 2020-07-28T13:21:05+00:00 Pranith Kumar K pkarampu@redhat.com 2020-05-29T08:54:53+00:00 e8aedcd40f9f24e5b821e1539275e40ebfccca94 Problem: AFR doesn't delay post-op for fsync fop. For fsync heavy workloads this leads to un-necessary fxattrop/finodelk for every fsync leading to bad performance. Fix: Have delayed post-op for fsync. Add special flag in xdata to indicate that afr shouldn't delay post-op in cases where either the process will terminate or graph-switch would happen. Otherwise it leads to un-necessary heals when the graph-switch/process-termination happens before delayed-post-op completes.

Problem:
AFR doesn't delay post-op for fsync fop. For fsync heavy workloads
this leads to un-necessary fxattrop/finodelk for every fsync leading
to bad performance.

Fix:
Have delayed post-op for fsync. Add special flag in xdata to indicate
that afr shouldn't delay post-op in cases where either the
process will terminate or graph-switch would happen. Otherwise it leads
to un-necessary heals when the graph-switch/process-termination
happens before delayed-post-op completes.
