Hi guys:
I have just installed gluster on a single instance, and the command:
gluster volume create gv0 replica 2 server.n1:/export/brick1
server.n1:/export/brick2
returns with:
"Failed to perform brick order check... do you want to continue ..? y/N"?
What is the meaning of this error message, and why does brick order
matter?
The second half of that question that I neglected to answer is that
brick order matters due to establishing replica sets.
A replica set, "replica N" is each N bricks listed in order. So for this
command:
gluster volume create myvol1 replica 2 s1:/brick s2:/brick s3:/brick
s4:/brick s5:/brick s6:/brick
There would be three replica sets, s1:/brick+s2:/brick,
s3:/brick+s4:/brick, and s5:/brick+s6:/brick, that will be combined
using distribute to create the volume myvol1.
If you wanted a little more redundancy, then:
gluster volume create myvol2 replica 3 s1:/brick s2:/brick s3:/brick
s4:/brick s5:/brick s6:/brick
Would create 2 replica sets, s1:/brick+s2:/brick+s3:/brick, and
s4:/brick+s5:/brick+s6:/brick. Again they will be combined using
distribute to create the volume myvol2.
