[Gluster-users] Max recommended brick size of 100 TB

Hello, I read in the Gluster Getting Started leaflet (https://lists.gnu.org/archive/html/gluster-devel/2014-01/pdf3IS0tQgBE0.pdf) that the max recommended brick size should be 100 TB. Once my storage server nodes filled up with disks they will have in total 192 TB of storage space, does this

[Gluster-users] How to convert from 2 node replicated to 4 node distributed-replicated

Hi, Is it possible to convert a 2 nodes replicated volume to a 4 nodes distributed-replicated volume? If yes, is it as simple as just issuing the add-brick with the two additional nodes and then start a rebalance? And can this be repeated ad infinitum? Let's say I want to add again another 2

[Gluster-users] Guideline for Gluster hardware

Hello, I am currently testing GlustserFS and could not find any guidelines or even rules of thumb on what kind of minimal hardware requirements for a bare metal node. My setup would be to start with two Gluster nodes using replication for HA. For that I have two 4U SuperMicro storage servers

[Gluster-users] GlusterFS with FUSE slow vs ZFS volume
