Hello,
Short way: Is there any way to define a preferred Gluster server ?
Long way:
I have the following setup (version 3.6.3) :
Gluster A <==> VPN <==> Gluster B
Volume is replicated between A and B.
They are in same datacenter, using a 1Gb/s connection, low latency (0.5ms)
I have gluster clients in lan A & B.
When doing a "ls" on big folder (~60k files), both gluster node are
used, and so it need 9mn instead on 1mn if only the local gluster is
reachable.
Lookups (and writes of course) from clients are sent to both bricks
because AFR uses the result of the lookup to select which brick to read
from if there is a pending heal etc.
If the file is clean on both A and B, then reads are always served from
the local brick. i.e. reads on clients mounted on A will be served from
the brick in A (and likewise for B).
Hope that helps,
Ravi
It's HA setup, application is present on both side. I would like a
master/master setup, but using only local node as possible.
