Replace brick code has some issues. Hence there are plans to retire
replace brick for cases where data migration is required (there was a
discussion in gluster-devel about it). However we can use add brick and
remove brick in a way which will work as a replacement for
replace-brick. Below are the steps.
* Add new brick
# gluster volume add-brick <VOLNAME> [<replica>
<COUNT>] <NEW-BRICK> ...
* *Do not**run rebalance*
* Remove old brick
#gluster volume remove-brick <VOLNAME> [replica <COUNT>]
<BRICK> ... start
* #gluster volume remove-brick <VOLNAME> [replica <COUNT>] <BRICK> ...
status
* Once status shows all completed,
* #gluster volume remove-brick <VOLNAME> [replica <COUNT>] <BRICK> ...
