glusterfs.git/tests/basic/afr/sparse-file-self-heal.t, branch v3.6.3 afr: Don't write to sparse regions of sink. 2015-02-03T13:24:56+00:00 Ravishankar N ravishankar@redhat.com 2015-01-23T05:42:54+00:00 f397d7edb85c1e4b78c4cac176dc8a0afe8cf9a8 Backport of http://review.gluster.org/9480 Problem: When data-self-heal-algorithm is set to 'full', shd just reads from source and writes to sink. If source file happened to be sparse (VM workloads), we end up actually writing 0s to the corresponding regions of the sink causing it to lose its sparseness. Fix: If the source file is sparse, and the data read from source and sink are both zeros for that range, skip writing that range to the sink.

Backport of http://review.gluster.org/9480

Problem:
When data-self-heal-algorithm is set to 'full', shd just reads from
source and writes to sink. If source file happened to be sparse (VM
workloads), we end up actually writing 0s to the corresponding regions
of the sink causing it to lose its sparseness.

Fix:
If the source file is sparse, and the data read from source and sink are
both zeros for that range, skip writing that range to the sink.
