Trouble to add brick

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

Thx for your help.

I finaly could add the last brick .

I now have a Distributed-replicated volume

> gluster volume info
>
> Volume Name: dccbackup
> Type: Distributed-Replicate
> Status: Started
> Number of Bricks: 2 x 2 = 4
> Transport-type: tcp
> Bricks:
> Brick1: mysqldccbackup:/export
> Brick2: mysqldccbackupmirror:/export
> Brick3: gfsbrick1:/brick1
> Brick4: gfsbrick2:/brick2

On the client side though  I don't see any increasing in storage size.
I tried to rebalance

gluster volume rebalance  dccbackup fix-layout start

and got .

> starting rebalance on volume dccbackup has been unsuccessful

I'm kind of stuck here.

Thank you

KL
