Let's assume a 100GB virtual machine image (qcow2 or whatelse) with 64MB shards One users does this: "touch /tmp/test" inside this virtual machine, during the node downtime. Gluster will "update" only the involved shard, right ? Thus, when node comes back, only that single shard must be healed, maybe a 64MB shard on a 100GB image. Without sharding, a single "touch" would require the whole 100GB to be sharded ? What happens to the virtual machine, during the shard healing? Only files included in that shard are set as read-only? Or all files included in that shard are hidden ? What if a file is spread across multiple shards and one of these shards need healing ? _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-users
