Apologies for the late reply. Further to this, if my Linux clients are connecting uing glusterfs-fuse and I have my volumes defined like this: dc1srv1:/gv_fileshare 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?
