[Gluster-users] how 'diff' cluster.data-self-heal-algorithm works?
if cluster.data-self-heal-algorithm set to ?diff?,just copies to sinks only those blocks whose checksums don't match with those of source. my questions: 1.how to know the block size? 2.blocks? checksums was stored when writing files or not stored and just need to be computed when self-healing? Thank you! Best Regards, David -------------- next part -------------- An HTML attachment was scrubbed...
