Gluster users - Apr 2013 - Gluster volumes with different size

Hi!

We have "problems" with size of volumes after replace three bricks,
our
farm of gluster it's configured with Stripped-Distributed-Replicate
scheema with 8 bricks of 2TB.

Brick 1 	/gfs	Used 70%
Brick 2		/gfs	Used 47%
Brick 3 	/gfs	Used 60%
Brick 4		/gfs	Used 52%
Brick 5		/gfs	Used 25%
Brick 6		/gfs	Used 16%
Brick 7		/gfs	Used 15%
Brick 8		/gfs	Used 52%

The new bricks after replace process without problems are, 5, 6 and 7.

Our question is...it's normal? Have we to do something? Rebalance volume
it's secure and necessary?

Version of gluster 3.3.0 with Infiniband Network.


Thanks!

Rebalance is a safe thing to do - but could cause a lot of heavy IO.

I'm curious on your Infiniband setup, I'm using Infniband as well but
using IPoIB. When I've tried native RDMA I've had extremely poor
performance. Can you show me your gluster volume and how you are
mounting over fuse? Want to see if I'm missing something major.
