Hi,

I'm trying to expand my replicated volume but am getting an error. My goal is to double my capacity by adding new volumes.  Any suggestions?

# gluster volume info

Volume Name: eproduct

Type: Replicate

Volume ID: 1325b138-9777-4d76-9701-6410c0ff35d9

Status: Started

Number of Bricks: 1 x 2 = 2

Transport-type: tcp

Bricks:

Brick1: staging1:/export/brick1

Brick2: staging2:/export/brick1

(I created a new volume /export/brick2 on each of the two servers)

# gluster volume add-brick eproduct staging1:/export/brick2 staging2:/export/brick2

volume add-brick: failed: /export/brick2 or a prefix of it is already part of a volume

Looks like export brick "/export/brick2" was part of some other gluster volume before. Brick has some xattrs which needs to be cleared before adding them to the gluster volume.

This should help you.

Note that you will have to run rebalance after adding new bricks.

Would appreciate suggestions as to what I need to do to add new volumes to give me larger storage capacity.

Thanks!

WILL
