...it seems recommended to use XFS over LVM before creating & using gluster volumes.

For example , on a dedicated server with disks & partitions that will not change of size, it doesn't seems necessary to use LVM. I can't understand clearly wich partitioning strategy would be the best for "static size" hard drives :...

As far as I understand the documentation the answer in your case is "5". See: https://docs.gluster.org/en/v3/Administrator%20Guide/Managing%20Volumes/#expanding-volumes "... When expanding distributed replicated and distributed dispersed volumes, you need to add a number of bricks that is a multiple of the replica or disperse count. ..." One suboptimal idea could be: divide the new device in 5 partitions and add these 5 partitions a...

Is possible to create a dispersed volume 1+2 ? (Almost the same as replica 3, the same as RAID-6) If yes, how many server I have to add in the future to expand the storage? 1 or 3? -------------- next part -------------- An HTML attachment was scrubbed...

This recommendations was added after gluster-snapshot. Gluster snapshot relays on LVM snapshot.

We have a Gluster setup with 2 nodes (distributed replication) and we would like to switch it to the distributed mode. I know the data is duplicated between those nodes, what is the proper way of switching it to a distributed, we would like to double or gain the storage space on our gluster storage node. what happens with the data, do i need to erase one of the nodes? Jose

...ch I want to discard. I don't want to reconnect it right away because I'm not sure what's the state of the data on this brick for Gluster, I'd just like to discard everything and sync from the running brick. I red http://docs.gluster.org/en/latest/Administrator%20Guide/Managing%20Volumes/#replace-faulty-brick but my setup has some differences (I'm in pure replication mode, no distribution, and I'm not replacing a brick, I just want to bring back a previously existing one, I just want to be sure Gluster will discard its data and sync from the other, and not create a spli...
