Interesting table Karan!, Could you please tell us how you did the benchmark? fio or iozone orsimilar? thanks Arman.

...re dc2srv1:/gv_fileshare dc1srv2:/gv_fileshare dc2srv2:/gv_fileshare (replica 2) How do I ensure that clients in dc1 prefer dc1srv1 and dc1srv2 while clients in dc2 prefer the dc2 servers? Is it simply a matter of ordering in /etc/fstab?

Hi all I've googled but can't find an answer to my question. I have two data centers. Currently, I have a replica (count of 2 plus arbiter) in one data center but is used by both. I want to change this to be a distributed replica across the two data centers. There is a 20Mbps pipe and approx 22 ms latency. Is this sufficient? I really don't want to do the geo-replication in its

Hi gluster users, I've spent several months trying to get any kind of high performance out of gluster. The current XFS/samba array is used for video editing and 300-400MB/s for at least 4 clients is minimum (currently a single windows client gets at least 700/700 for a single client over samba, peaking to 950 at times using blackmagic speed test). Gluster has been getting me as low as

...t. The files and directories were there, however, if you accessed them directly. Server are 3.10.5 and the clients are 3.10 and 3.12. Any ideas?

Hello To my two node replica volume I have added an arbiter node for safety purpose. On that volume I also have geo replication running and would like to stop it is status "Faulty" and keeps trying over and over to sync without success. I am using GlusterFS 3.8.11. So in order to stop geo-rep I use: gluster volume geo-replication myvolume gfs1geo.domain.tld::myvolume-geo stop but it
