Hi All,<div><br></div><div>Trying to wrap my head around GlusterFS (pretty new to clusterd/distributed file storage systems) but am unsure on a few things that I can't seem to find the answers to.. Hopefully the members of the list don't mind clearing it up for me..</div>
<div><br></div><div>Firstly am I on the right track with my understanding of the storage methods.. This is how I read it and relate it to RAID terminology..</div><div>Distributed = JBOD</div><div>Replicated = RAID1</div><div>
Striped = RAID0</div><div>Distributed Striped = JDOD/RAID0??</div><div>Distributed Replicated = JBOD/RAID1??</div><div><br></div><div>If I had 10 bricks in a replicated volume would the the effective storage capacity be half the total storage capacity as is the case with RAID1?</div>
<div><br></div><div>Next area I am not sure of.. Does GlusterFS only store complete files or chunks of files on bricks?</div><div>I am looking to store Virtual Machine image files of anything up to 100GB.. Would the whole 100GB file be resident on one brick? or stored over a number of bricks?</div>
<div><br></div><div>If running a replicated volume and a brick is removed permanently, will the data that now is not replicated be automatically replicated to another brick?</div><div><br></div><div>Sorry for the simplistic questions but these things weren't obvious in the docs..</div>
<div><br></div><div>Thanks in advance..</div>
