<div>Most probably you use sharding , which splits the files into smaller chunks so you can fit a 1TB file into gluster nodes with bricks of smaller size.</div><div>So if you have 2 dispersed servers each having 500Gb brick-> without sharding you won't be able to store files larger than the brick size - no matter you have free space on the other server.</div><div><br></div><div>When sharding is enabled - you will see on the brick the first shard as a file and the rest is in a hidden folder called ".shards" (or something like that).</div><div><br></div><div>The benefit is also viewable when you need to do some maintenance on a gluster node, as you will need to heal only the shards containing modified by the customers' data.<br></div><div><br></div><div>Best Regards,</div><div>Strahil Nikolov<br></div><div><br></div><div><br></div>
