Assume I have 4 bricks in a replica (count=2) volume:

Volume Name: data-vol

Number of Bricks: 2 x 2 = 4

Brick1: 192.168.1.101/brick

Brick2: 192.168.1.102/brick

Brick3: 192.168.1.103/brick

Brick4: 192.168.1.104/brick

Something happens to Brick3 and I want to replace it by 192.168.1.105/brick

What command should I use to replace 192.168.1.103/brick by 192.168.1.105/brick?

Can I use:

gluster volume replace-brick data-vol 192.168.1.103/brick 192.168.1.105/brick commit force?

This is the correct choice. Since you have replaced a replica brick, you will have to follow up with 'gluster vol heal data-vol full` to restore data from 104/brick to 105/brick.

Or I have to start _replace-brick_ first then commit it?

Thanks,
