With this scheme, self-healing (and rolling checksum computation thereby) happens only on those fragments that undergo changes when one of the nodes in a replicated set is offline. This has shown nice improvements in gluster's resource utilization during self-healing. Does it effect read speed and random i/o? I guess that would depend on the methodology used to calculate shard location for a given block. Could be quite interesting on top of zfs, love to test.
Krutika has been working on several performance improvements for sharding and the results have been encouraging for virtual machine workloads.
Testing feedback would be very welcome! Thanks, Vijay _______________________________________________ Gluster-users mailing list Gluster-users@gluster.org http://www.gluster.org/mailman/listinfo/gluster-users
