Hi & thanks, Well, obviously my intention is not to create a mess, but the reason for redundancy is probably that servers may disappear from the cluster for a while. In case I run any glusterfs commands related to the volume definition at that time, those changes will not reach the unavailable

glusterd should handle syncing any changes you make with the "gluster" command to the peers, obviously if you make local changes to the volume file on one server you are likely to break things unless you copy rsync the changes to the other server. On 22 September 2015 at 04:02, Andreas Hollaus w

Hi Pranith,I’m sorry but I cannot bring you any comparison because comparison will be distorted by the fact in my HPC cluster in production the network technology is InfiniBand QDR and my volumes are quite different (brick in RAID6 (12x2TB), 2 bricks per server and 4 servers into my pool)Concerning

hi Geoffrey, Since you are saying it happens on all types of volumes, lets do the following: 1) Create a dist-repl volume 2) Set the options etc you need. 3) enable gluster volume profile using "gluster volume profile start" 4) run the work load 5) give output of "gluster volume
