Hi Gluster Users,
I am hoping that someone can help me put me on the right track maybe ..
Objective is to have a high available, extensible storage cluster with a
fair rate of redundancy.
I was thinking of a cluster of multiple machines, starting with 2
servers, 2 disks each and a config of
Volume Name: originals
Type: Distributed-Replicate
Volume ID: xx
Status: Started
Number of Bricks: 2 x 2 = 4
Transport-type: tcp
Volume: originals
Brick srv1:/srv/vol1 (/dev/sdb1 500GB)
Brick srv1:/srv/vol2 (/dev/sdc1 500GB)
Brick srv2:/srv/vol1 (/dev/sdb1 500GB)
Brick srv2:/srv/vol2 (/dev/sdb1 500GB)
Now I would like to add another server with JUST 1 500GB disk, peer
probe and everything is fine so far, but when it comes to adding the brick:
root@srvdst01:~# gluster volume add-brick videos srv3:/srv/vol1
volume add-brick: failed: Incorrect number of bricks supplied 1 with count 2
Ok, trying to change the num of replica's or whatever just results in
root@srvdst01:~# gluster volume add-brick videos replica 3
srv3:/srv/vol1 (or vol3 or vol4, this doesnt matter)
volume add-brick: failed: Operation failed
No way to get around this .. What do I have to do ? Add two bricks in 1
command ? How would it work in the future when I gets to production
machines with each 2 or even more disks ?
Were great someone could gimme a hint.
Its gluster 3.4.2-1ubuntu1 amd64 on ubuntu 14.04 LTS.
regards, Oliver
