I have 2 data centers in two different region, each DC have 3 severs, I
have created glusterfs volume with 4 replica, this is glusterfs volume info
Volume Name: test-halo
Snapshot Count: 0
Number of Bricks: 1 x 4 = 4
bricks with ip 10.0.0.1 & 10.0.0.3 are in region A and bricks with ip
10.0.0.5 & 10.0.0.6 are in region B
when I mount the volume in region A, I except the data first store in
brick1 & brick2, then asynchronously the data copies in region B, on brick3
Am I write? this is what halo claims?
If yes, unfortunately, this not happen to me, no differ I mount the volume
in region A or mount the volume in region B, all the data are copied in
brick3 & brick4 and no data copies in brick1 & brick2.
ping bricks ip from region A is as follows:
ping 10.0.0.1 & 10.0.0.3 are bellow time=0.500 ms
ping 10.0.0.5 & 10.0.0.6 are more than time=20 ms
What is the logic that the halo select the bricks to write to?if it is the
access time, so when I mount the volume in region A, the ping time to
brick1 & brick2 is bellow 0.5 ms, but the halo select the brick3 &
glusterfs version is:
I really need to work with halo feature, But I am not successful to run
this case, Can anyone help me soon??
