Hi everyone, I've read on the gluster & redhat documentation, that it seems recommended to use XFS over LVM before creating & using gluster volumes. Sources : https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3/html/Administration_Guide/Formatting_and_Mounting_Bricks.html http://gluster.readthedocs.io/en/latest/Administrator%20Guide/Setting%20Up%20Volumes/ My point is : do we really need LVM ? For example , on a dedicated server with disks & partitions that will not change of size, it doesn't...

Hi I'm looking for an advise to configure a dispersed volume. I have 12 servers and would like to use 10:2 ratio. Yet RH recommends 8:3 or 8:4 in this case: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Administration_Guide/chap-Recommended-Configuration_Dispersed.html My goal is to create 2PT volume, and going with 10:2 vs 8:3/4 saves a few bricks. With 10:2 I'll use 312 8TB bricks and with 8:3 it's 396 8TB bricks (36 8:3 slices to evenly distribute between all servers/bricks)...

Hi all. I'm looking to see if anyone can tell me this is already working for them or if they wouldn't mind performing a quick test. I'm trying to set up a geo-replication instance on 3.2.5 from a local volume to a remote directory. This is the command I am using: gluster volume geo-replication myvol ssh://root at remoteip:/data/path start I am able to perform a geo-replication
